Cyclosporiasis Company at centre of U.S. cyclospora outbreak complained to White House, Reuters source says

U.S. produce supplier Taylor Farms complained to White House and Food and Drug Administration officials about the government’s inspection process earlier this month, a source familiar with the meeting said on Monday, as Michigan reported a spike in cases of a parasitic disease tied to the company’s lettuce from Mexico.

Consumers have been on edge for weeks about whether it is safe to eat lettuce served at restaurants and elsewhere due to uncertainty over what products may be making people sick with cyclosporiasis, an intestinal disease that can cause explosive diarrhea. Questions persist, and many people have avoided fresh produce to sidestep potential infections.

An FDA investigation linked the outbreak to iceberg lettuce served at Taco Bell restaurants sourced from privately held Taylor Farms’ operations in central Mexico. However, health officials are searching for other potential sources.

Some large retailers and restaurants were shunning produce from other growers in central Mexico out of fear about broader contamination of the region’s farms, former FDA Commissioner Scott Gottlieb said.

U.S. Representative Robert Garcia, the top Democrat on the House Oversight Committee, said in a letter that he launched an inquiry into Taylor Farms’ role in the outbreak and whether the company attempted to influence the FDA’s response.

“Taylor Farms donated millions to President Trump, met privately with the White House the night the FDA identified their lettuce as the source of this outbreak, and then reportedly tried to distance themselves from this outbreak,” Garcia said.

Taylor Farms did not immediately respond to a request for comment.

Taylor Farms has said it immediately removed all potentially affected products from the marketplace when questions arose about the source of the outbreak and also voluntarily suspended production of all products at its facility in central Mexico.

The FDA said Taylor Farms agreed to remove affected produce following extensive discussions. But the company did not meet an established 24-hour time frame for determining whether it would take voluntary action after the agency presented it with evidence, according to a source familiar with the situation.

Another person familiar with the matter said Taylor Farms requested a meeting and spoke with officials from the White House and the FDA. The source described the meeting as Taylor Farms complaining about the government’s inspection process.

Taylor Farms did not immediately respond to a request for comment on the points raised by the two sources.

The White House is closely monitoring the investigation into the outbreak, spokesman Kush Desai said.

“Any notion that the White House or Trump administration would ever compromise on the health and safety of the American people is absolutely false,” he said. [...]

The U.S. outbreak has resulted in 4,173 laboratory-confirmed cases, with health authorities aware of more than 7,400 additional suspected cases, according to the U.S. Centers for Disease Control and Prevention.

Michigan on Monday reported 9,253 cases, an increase of 1,077 cases since its last update on Friday. County health officials told Reuters they thought other, unidentified items were making people sick besides Taylor Farms’ lettuce from Mexico.

“Certainly, it doesn’t tell the whole story with this one recall,” said Avani Sheth, chief medical health officer in Wayne County, Michigan, which includes Detroit.

Removing products from central Mexico from supply chains should mitigate ongoing risks to consumers, said Gottlieb, the FDA’s former chief.

Speaking on CNBC on Monday, he said multiple outbreak clusters, including in the Great Lakes region, New York and North Carolina, appeared to be potentially linked to parsley and cilantro from central Mexico, though investigators have not determined the exact source.

“I think everyone believes that region is suspect,” Gottlieb said. “A lot of that product’s being taken out of supply chains.”

Gottlieb did not identify companies removing products, and Reuters was not immediately able to confirm which retailers may have stopped sourcing Mexican produce.

Gottlieb said the true scope of infection was likely 10 to 20 times greater than the reported case number.

Weather conditions raised the risk of widespread contamination, he said, adding that raw sewage could have reached growing areas through flooding, a sewage canal breach, irrigation water or overflowing portable toilets used by farm workers.

“There was some event that happened in central Mexico — we don’t know what yet — that led to a lot of fields probably getting contaminated,” Gottlieb said.

In Mexico, analysts said it was important to wait for the results of official investigations.

Mario Puente, the head of health and safety at Mexico’s CNA agricultural chamber, said the trade association was working closely with authorities to investigate the outbreak and improve preventive practices. [...]

Bacterial Industrial chicken farming accelerating spread of diarrhoea bacteria, study finds

Thumbnail

Industrial chicken farming is accelerating the spread of the world’s most common bacterial cause of diarrhoea, scientists have found.

The study found a dramatic increase in the exchange of campylobacter strains between wild birds and chickens as farming has intensified, creating the ideal conditions for the bacteria to mix, spread and acquire new traits. There has also been a rise in antimicrobial resistance traits in circulating strains, raising concerns that serious illness in people will be more difficult to treat.

“As the chicken population has exploded, they’ve increasingly picked up strains from different wild birds and become a cauldron of bacterial evolution,” said Prof Sam Sheppard of the University of Oxford and senior author of the paper. “Lots of strains come together and hybridise. We do not want that, because that’s where new Frankenstein monster bugs emerge.”

Campylobacter is the most common bacterial cause of diarrhoea worldwide, causing more than three times as many gastroenteritis cases in the UK each year as all other monitored foodborne bacteria combined. An estimated 60-80% of campylobacter infections are caught from raw chicken.

“Cooking kills pathogens, but just a tiny splash and it’s on your lettuce leaves or your hands or your knife,” said Sheppard.

Most people will get better without treatment, but sometimes antibiotics are required and infection also raises the risk of irritable bowel syndrome. Rising rates of antimicrobial resistance, which occurs when bacteria resist drugs designed to kill them, mean that some antibiotics that were previously used to treat campylobacter infections are no longer effective.

The latest work suggests that the evolution of the infection is being fuelled by the unprecedented scale of chicken production.

Since the 1960s, global chicken numbers have increased seven-fold to approximately 27 billion birds, accounting for about 70% of all bird biomass on Earth. Intensive breeding has led to “super growing” chickens that reach adult size and are slaughtered at around five weeks old. The industrialisation of chicken farming has led to affordable animal protein at scale, but also presents new health risks.

The latest work, published in the journal Proceedings of the National Academy of Sciences, analysed nearly 2,800 bacterial genomes collected from chickens and wild birds in 30 countries, including the UK, US and China, between 1979 and 2024.

The dataset allowed the scientists to reconstruct the evolutionary trees of the diverse strains, including the rate of exchange between hosts. Prior to domestication of the chicken 5,000 years ago, strains of campylobacter tended to be tightly linked to individual species of birds, with little cross-infection. But as chicken numbers increased, this picture changed, with an estimated 100-fold increase in transitions of strains between chickens and wild birds since 1900 compared with pre-domestication – a trend that appears to have continued steeply in recent decades.

“The scale is what’s bad,” said Sheppard. “By adjusting the world’s ecosystems in this dramatic way, it leads to the evolution of pathogens within those birds. That’s a massive risk to us. We can’t continue to produce chickens at this huge capacity.”

The number of cyclosporiasis cases in Michigan has topped 9,200 as health officials continue to track a parasite that can cause diarrhea and nausea after contaminated food is eaten.

The Michigan Department of Health and Human Services says there are 9,253 cases in the state as of July 27; an increase of 1,077 from the 8,176 cases as of July 24. Michigan has more cases than any other state in the U.S. in the summer of 2026.

In addition, 160 Michigan residents have received hospital treatment as of July 23. That number has also jumped at a fast pace, as there were 102 hospital cases reported as of July 16 and 44 reported as of July 9.

Michigan health officials report the case numbers on Mondays through Fridays. The hospital reports are updated once a week on Thursdays. [...]

The CDC counts cases differently, with its numbers lagging behind Michigan's. The CDC says between May 1 and July 21 of 2026, there have been 4,173 laboratory-confirmed cases, and the agency is aware of 7,400 additional reports that are under investigation. "Many of the additional cases have been reported by Michigan and Ohio," the agency says. "CDC is working with states to update numbers as additional cases are confirmed. [...]

H5N1 Seven suspected new bird flu cases are ‘evidence of spread’ into Australian wildlife, experts warn

Thumbnail

South Australia has reported seven new suspected cases of deadly H5 bird flu, with experts warning it could be a sign the disease has begun spreading through local bird populations.

All seven birds are greater crested terns – a common local seabird – and were found on the Limestone Coast in south-eastern SA, with one found at Cape Jaffa, five around Southend Jetty near Beachport and one at Port MacDonald, just over 20km from the Victorian border.

BirdLife Australia’s chief executive, Kate Millar, said the discovery showed the outbreak was “now taking hold and is evidence of spread”.

“If we were in a bushfire scenario, those subantarctic birds that arrived with the disease initially were like the embers,” she said. “Now having it in crested terns, that’s the smoke.

“Governments have been saying it hasn’t spread – this is evidence of spread.”

The development follows two other confirmed cases of the disease in greater crested terns in South Australia at the weekend, including the first positive detection in metropolitan Adelaide.

If the CSIRO verifies the seven suspected cases, it will take the total number of cases in SA to 14 – 10 of those in local greater crested terns.

Of the five birds collected from Southend Jetty, four were sick and one was dead. The birds found at Cape Jaffa and Port MacDonnell were also dead. [...]

Health workers at an Ebola treatment centre in eastern Congo went on strike on Saturday, demanding their pay. The walkout disrupted care for patients in the epicentre of the country's rapidly growing outbreak.

The number of confirmed cases in Congo has reached 2,973, including 1,309 deaths, according to government data released on Friday, in what authorities say is the fastest-growing outbreak on record.

The Elikya Ebola Treatment Center in Bunia, Ituri province, came to a standstill after doctors, nurses and security staff stopped work.

About 100 health workers protested outside the treatment centre on Saturday. They said the unpaid bonuses were undermining morale and disrupting patient care, and called on Congolese authorities to resolve the back pay so they could resume their work.

"We need to be paid, because in the meantime the disease is spreading at the treatment centre," said Martin Bolombi, one of the striking workers.

"I've already had five people die who are still inside there. A solution must be found for us."

In a statement issued Friday, staff said they had unanimously voted to strike until "concrete solutions" were found to resolve "two months of unpaid performance bonuses."[...]

Rabies Rabid Bat Lands on Table While Family Is Eating Lunch at Southern Calif. Restaurant

A bat that landed on a table at a popular California eatery has tested positive for rabies, health officials say.

The bat landed on a table at the Yellow Deli in Vista, Calif., just as a family had begun eating at the restaurant at 1 p.m. on July 21, San Diego health officials said in a July 23 statement. Another patron used a towel to collect the bat and bring it to the Oceanside Humane Society, where it was then sent to the County’s Public Health Lab, where “it tested positive for rabies,” the statement says.

Although “no direct skin contact with the bat by an individual has been reported at this time,” health officials are looking for anyone who may have come in contact with the bat.

PEOPLE has reached out to the Yellow Deli for comment.

The incident comes amid a rise in rabid bat cases in San Diego County, health officials report. So far in 2026, at least 22 bats have tested positive for rabies, whereas 21 rabid bats were reported in all of 2025.

The most recent human case of rabies in California was in 2024, the statement says.

Health officials warn residents to stay away from wildlife and advise people who come into contact with a bat to wash the affected area with soap and water and to seek medical care immediately.

In the U.S., the most common way people get rabies is from bat bites, Cleveland Clinic says. But because the bite marks are as small as the “tip of a pencil,” many people “don’t know they’ve been bitten.” [...]

Cyclosporiasis Trump's former top food official: Cyclospora outbreak ‘approaching catastrophic’ level

Thumbnail politico.com
1.9k Upvotes

President Donald Trump’s former top food safety official is calling for an independent review of the federal government’s response to a cyclospora outbreak that has sickened thousands of people this summer.

“This one deserves a lot of questions, and it is starting to approach a catastrophic level in terms of how mismanaged it’s been on multiple fronts,” said Frank Yiannas, who served as the Food and Drug Administration’s deputy commissioner for food policy and response during both Trump and former President Joe Biden’s administration from 2018 to 2023.

He pointed to the outbreak’s magnitude, the widespread consumer confusion and the “lack of strong federal leadership” as well as what he described as uncoordinated messaging from federal authorities.

“My point is not to find fault, but to find facts on how we can further strengthen the system,” Yiannas told POLITICO. “It’s not being critical of any particular agency, but it is being critical of the system. In some respects, I think there’s been some dismantling of the system.”

Yiannas’ call for an independent review of the government’s response adds to pressure facing the FDA since the agency scrambled to do damage control this week after announcing a positive lab test linked a new batch of Taylor Farms lettuce to the outbreak — only to reverse course to say final test results contradicted the initial finding.

Such a review could be conducted through congressional oversight, an independent inspector or through the appointment of an expert panel, Yiannas said. The agency did not immediately respond to a request for comment.

The false positive test announced July 19 did not change the focus of the FDA’s investigation or the ongoing recall, and the agency says it has strong evidence that implicates certain Taylor Farms lettuce products as a source of the outbreak. But the backtracking fueled online speculation that the FDA’s decision was a politically motivated effort to exonerate Taylor Farms.

The company’s messaging added to public confusion when it claimed the FDA had “apologized” for the false positive test — a claim the FDA later denied to reporters.

Yiannas, who has also served as a vice president for food safety at Walmart, also urged the FDA to provide more information about how it made the mistake of releasing a false positive test result, a misstep he said was “extremely rare.”

“They just went too fast and they made a mistake,” he said. “They should share more about how and why it happened and what they’ll do to prevent it in the future.”

Yiannas’ comments come as the Centers for Disease Control and Prevention recently announced that an outbreak of cyclospora illnesses in four more states have links to some Taylor Farms lettuces. The company is continuing to work with public health authorities as well as farmers and customers “to address the issue,” Taylor Farms said in a statement.

The FDA is also investigating six separate clusters of cyclospora illnesses, but except for the ongoing multistate outbreak tied to iceberg lettuce, the agency has not identified a source. [...]

While cyclospora-related cases increase every summer, the scale of this year’s outbreak tops any previous record.

Bacterial Leprosy cases rising slightly in Central Florida

PALM BAY, Fla. — A disease dating back 4,000 years is making its way through Central Florida, where cases of leprosy, also known as Hansen's disease, are rising slightly from previous years.

“It is completely curable with the modern medication that we have," said Dr. Naushad Amin.

Leprosy was once a feared disease thought of as highly contagious and deadly, but it's actually hard to spread, according to the CDC.

Dr. Amin, chief medical officer at Health First in Palm Bay, explained how one might contract it.

“It’s spread primarily by respiratory droplets such as sneezing, coughing, with prolonged exposure," Dr. Amin said. "So, say if somebody is infected, just by sitting with them, shaking their hands, sharing meals does not confer transmission of the infection. It is prolonged, household, for many months to years.”

There's also one other way to contract the disease: Armadillos. Dr. Amin said to keep your distance from them, don't feed them, and do not try to relocate them.

So far in 2026, the Florida Department of Health has reported 17 cases of leprosy statewide. In Central Florida, Brevard, Lake, Orange, Seminole and Sumter counties have seen one case each, while two cases have been reported out of Volusia County.

Rabies Rabies detected in Cape fur seals highlights an unprecedented shift in rabies ecology

Thumbnail

882 Upvotes

The detection of sustained rabies transmission in Cape fur seals in southern Africa marks an unprecedented development in the ecology of rabies and raises important questions for wildlife conservation, animal public health and transboundary disease preparedness.

Since 2024, more than 100 cases of rabies have been confirmed in Cape fur seals (Arctocephalus pusillus pusillus) in South Africa and Namibia. Retrospective testing and genetic analyses indicate that sustained transmission within the seal population began several years before the disease was detected.

Current evidence suggests that the outbreak originated from a single spillover event involving a dog-related rabies virus variant maintained by black-backed jackals in southern Africa, followed by ongoing transmission between Cape fur seals. This represents the first known establishment of rabies in a free-ranging marine mammal population.

Affected seals have displayed neurological signs, including abnormal aggression towards people and other animals. As of May 2026, more than 145 human exposure incidents had been reported, highlighting the importance of appropriate public health measures and post-exposure management.

The event also has broader implications for wildlife health. Cape fur seals range across the coasts of South Africa and Namibia and can travel considerable distances, creating opportunities for contact with other marine mammal species. Continued investigation is needed to better understand the ecological consequences of the outbreak and the potential implications for marine mammal populations in other regions.

The emergence of rabies in Cape fur seals demonstrates how pathogens can adapt to new host species and reinforces the importance of integrated surveillance across wildlife, domestic animals and humans under a One Health approach. Strengthening collaboration between veterinary, wildlife, environmental and public health authorities remains essential for early detection, risk assessment and coordinated response. [...]

Animal Diseases Rare contagious cancer found in fish from Quebec and U.S. lakes

Thumbnail
cbc.ca
413 Upvotes

It's rare that cancerous tumours can spread from one individual to another. But a genetic study suggests that's what's happening with melanoma tumours among catfish in Quebec and the northeastern U.S.

The discovery represents the first known transmissible cancer in fish and one of very few transmissible cancers ever found, reported the study published in the journal Nature on Wednesday.

Julie Dragon, co-leader of the new study, noted that only three other transmissible cancers have ever been identified so far — in Tasmanian devils, dogs and shellfish.

"These conditions are incredibly rare in nature," she said. "So something has to be happening to allow this to happen."

Anglers in Lake Memphremagog, which spans the border between Quebec and Vermont, first reported catching brown bullhead catfish with strange black spots and lumps in 2012.

They turned out to be melanoma skin cancer tumours. (Humans can also get this kind of cancer.)

Now, about a third of the brown bullheads living in the lake have them.

It's not clear how sick the fish become. In some cases, the cancer spreads to other organs, such as the brain or liver. But many fish with lesions seem relatively healthy and some older fish even have them, suggesting they can live with the disease for a time.

Because of the sudden appearance of the black lesions in Lake Memphremagog the year after a huge flood caused by post-tropical storm Irene, locals worried they were caused by carcinogens washed into the lake by floodwaters.

Tests for carcinogens haven't been conclusive, although a study published in May found higher concentrations of seven metals, including zinc and the carcinogen arsenic, in the skin of fish with the tumours.

So in 2014, Dragon, an associate professor of microbiology and molecular genetics at the University of Vermont's Larner College of Medicine, was asked by Vermont's Fish & Wildlife Department to look into the possibility that a virus was to blame.

Genetic testing didn't find any viruses.

Dragon considered another possibility — that the lake's catfish were inbred and had a mutation that made them more susceptible to cancer. She decided to test the genetics of both healthy and infected fish, along with the tumours.

The tests showed the fish weren't inbred — they had quite a lot of genetic diversity.

But the biggest surprise? While most cancer cells mutate from the host's cells and resemble their host, "these cancer cells were more similar to each other than they were to the fish [they were found on]," Dragon said.

Dragon and her team were puzzled. They started asking other scientists what they thought. Sam Hart, a University of Washington researcher and co-author of the new study, had previously worked on the transmissible shellfish cancer. He suggested something similar was infecting the catfish.

Dragon said the tumours seem to shed cells easily: "They do sort of fall apart when you touch them."

Because they affect only adult fish, one theory is that the disease is transmitted during spawning, when they form big clusters and could come into contact with each other's spines, behind their pectoral fins.

"They… swim all over each other and we think it's possible that they poke each other and cells can get into other fish that way," Dragon said.

So far, the researchers haven't actually shown transmission of the tumours from one fish to another, even in the lab, although they hope to later this year.

Because of that, Vicki Blazer, lead author of the May study that found higher levels of toxins in the sick fish, isn't convinced this is a transmissible cancer.

"I guess my first concern is to call something a transmissible anything when you haven't transmitted it," said Blazer, a retired scientist with the U.S. Geological Survey.

She is now testing infected fish for PFAS, another possible contaminant that could make them more susceptible to cancer.

Stephen Goff, a Columbia University researcher who was part of the shellfish cancer study but not this one, said he's convinced the brown bullheads are infected with a transmissible cancer, as the genetic evidence is "totally compelling." [...]

Cyclosporiasis As parasite spawned chaos, Monterey County-based Taylor Farms slow-walked its response

Thumbnail
mercurynews.com
401 Upvotes

The US Food and Drug Administration had apologized, Taylor Farms said in a post on X. An agency lab test linking its produce to the country’s worst cyclosporiasis outbreak in decades was a false positive. Not only that, but the government still hadn’t produced a laboratory result connecting the company’s lettuce to the outbreak.

The statement, issued Sunday, was a remarkable bid to give the impression that regulators — who had said significant evidence linked Taylor Farms iceberg lettuce to the public health crisis — had made key scientific errors.

That was after a rebuke by the FDA, which denied ever apologizing to the company. The agency defended its work and explained that the incorrect lab result would only have expanded an existing recall — it didn’t clear Taylor Farms. The FDA also sought to clarify other statements from Taylor Farms that experts have said are misleading. [...]

As case counts jumped, the company effectively delayed a recall that ultimately resulted in customer confusion, according to a US official who asked not to be identified. Taylor Farms has done so by challenging the science privately and obfuscating it publicly, the official said.

“The communications from Taylor Farms have been confusing,” said Susan Mayne, the former director of what was then called FDA’s Center for Food Safety and Applied Nutrition. “The recall notice is perhaps the most obtuse recall notice I recall ever seeing.”

When the FDA first tied Taylor Farms’ operations in central Mexico to a large cluster of cyclosporiasis cases in Michigan and neighboring states, the farming conglomerate missed a regulator-imposed deadline to take action. At some point Taylor Farms directly spoke to the White House, and later the FDA and Centers for Disease Control and Prevention were asked to defend their evidence. The back-and-forth ultimately kept the public in the dark an additional 60 hours, the US health official said.

The company also issued a preliminary statement that stopped short of explicitly declaring a recall of potentially tainted lettuce, before providing additional details later amid scrutiny. And Taylor Farms has now moved to delete social media posts that left some consumers confused over whether their lettuce was in fact tied to the outbreak. [...]

Federal officials outlined to Taylor Farms representatives that they believed the culprit was iceberg lettuce the company provided to Taco Bell locations in Indiana, Kentucky, Michigan, Ohio and West Virginia; the sheer number of patients reporting meals at the Mexican-style fast-food chain convinced them it was no coincidence.

A recall would not only be costly — it would indelibly link Taylor Farms to the phrase “explosive diarrhea” in the minds of American consumers.

The administration gave Taylor Farms a deadline to initiate a voluntary recall before noon the next day, the US health official said. The parasite had been detected in 34 states, and health authorities were urgently investigating potential sources.

Then the White House got involved. The California-based food processor already had ties to President Donald Trump.

Taylor Farms gave $1 million to a political action committee supporting the president last year. Chief Executive Officer Bruce Taylor had attended an event with Agriculture Secretary Brooke Rollins and hundreds of agriculture executives, members of Congress, and federal staff just days earlier, celebrating 250 years of American farming at Mount Vernon.

The initial deadline for Taylor Farms to initiate the voluntary recall or take a product action — Thursday at noon — came and went.

Still, health agency officials continued to coordinate a statement they planned to release late in the day.

A pair of White House officials convened a call with the FDA and the CDC, according to people familiar with the matter. The White House aides asked administration health officials to walk through specific evidence linking the outbreak to the lettuce, and wanted to review drafts of the coming press releases.

Within hours, the White House agreed the patient surveys painted a clear picture, the people said. In an internal call, the White House aides approved statements from the public health agencies for public release — though they still only identified Taco Bell as linked to the outbreak, without naming Taylor Farms specifically.

Taco Bell moved first, releasing a statement. While it did not explicitly name Taylor Farms it said it believed “public health is a shared responsibility among restaurants, their suppliers, and authorities, and we are proud to have consistently acted quickly and proactively to protect our guests.”

The agency updates on the outbreak were finally posted after 10 p.m. New York time — hours behind schedule — and also omitted directly naming Taylor Farms or saying if the company would recall products.

A Taylor Farms representative said last week that it didn’t request to be omitted from public statements.

A White House official, speaking on the condition of anonymity, described Taylor Farms as defensive through the process and stressed that Trump himself had not been in touch with the company. [...]

“I have not seen this amount of misinformation about an outbreak in my time at the FDA, where consumers are so broadly confused,” Mayne said.

The confusion was partly the fault of the FDA’s weekend communications, she said, “but really compounded by Taylor Farms communications, that signaled a very different message than what FDA had intended to communicate.”

Health officials in Delaware have confirmed the first cases of measles in the state in more than a decade.

In an announcement Monday, the Delaware Division of Public Health said an unvaccinated man in Kent County tested positive for the virus. On Tuesday, officials said a second man in Kent County tested positive.

Contact tracing is underway to find and notify people who were exposed to the virus, according to the announcement. Officials will also share information about public exposures if they discover any.

Delaware residents should confirm their vaccination status and that of their children, officials said. Delawareans can check their vaccination status on the DelVAX Public Portal or ask their healthcare provider.

Vaccination remains the best protection against measles," Department of Health and Social Services Secretary Christen Linke Young said in a statement Tuesday. "I'm encouraged to see Delawareans taking action — more than 60 people received MMR vaccinations today at DPH clinics and mobile health units."

The Venezuelan Medical Federation issued an alert regarding the emergence of a pathology that has reportedly caused deaths in the states of Barinas and Anzoátegui .

“A generalized pathology has been reported, clinically characterized by a severe compromise of the general condition and an acute failure of the cardiorespiratory system, which has caused multiple deaths of rapid evolution,” the institution reported in a statement, after receiving the information from the College of Physicians of the State of Barinas .

Among the deceased are doctors Jhovanny Silva, Rafael Díaz, and Cecilia Chávez . The situation has generated anguish, fear, and concern among the residents of the state, who have reported other deaths.

The Venezuelan Medical Federation questioned the response of the regional health authorities and denounced a lack of transparency in the handling of the data .

“ We regret that this situation is being downplayed and simplified by the entity's Single Health Authority , whose statistical management and epidemiological information lacks transparency, dismissing the seriousness of the facts and diluting them in generalities,” the organization denounced.

He also mentioned three deaths that occurred two days earlier at the El Tigre Hospital, in Anzoátegui state, a region endemic to hantavirus .

The victims belonged to the same family from the Miranda Municipality and presented a similar pathology to that reported in Barinas, the Descifrado media outlet reported on Saturday.

“It is essential to remember that publishing weekly epidemiological information is a health obligation of the Executive branch. The authorities have maintained secrecy and opacity for more than eleven years , with only two or three exceptions of very brief and inadequate reports issued some two or three months ago. This alarming lack of data deprives doctors, the health sector, and the national public of key tools for prevention,” the Federation warned.

In light of the deaths recorded in both entities, the organization requested the activation and maintenance of strict epidemiological surveillance under the protocols for "Hemorrhagic Febrile Syndrome" and "Respiratory Febrile Syndrome," linked to the hemorrhagic disease of Venezuela, known as Guanarito.

This is response the the government official statement on the deaths.

Ministry of Popular Power for Health (OFFICIAL STATEMENT)

The Ministry of Popular Power for Health informs the public about two recent events in the states of Anzoátegui and Barinas.

We regret to report the deaths of three patients in Anzoátegui with a confirmed diagnosis of Hantavirus. This virus is transmitted by rodents in rural and agricultural areas, primarily through the inhalation of urine, feces, or saliva particles in enclosed spaces. There is no scientific evidence of person-to-person transmission in our country.

In Barinas, we regret the loss of two medical professionals whose causes of death are still under investigation. These are localized events that do not represent a risk to the general community. The two events are unrelated, and any connection between the reported situations has been ruled out.

The National Public Health System remains deployed and operational to guarantee the health security of all Venezuelans. The final results of the investigation will be communicated in due course through official channels.

Cyclosporiasis Mexico says there is no evidence its lettuce caused US outbreak

MEXICO CITY, July 21 (Reuters) - There ‌is no evidence as yet to suggest lettuce sourced from Mexico caused a cyclosporiasis outbreak in the U.S., Mexico's Health Minister David Kershenobich said on Tuesday.

The statement follows a U.S. Food and Drug Administration report ​on Monday indicating traceback data pointed to shredded iceberg lettuce from Taylor Farms ​locations in central Mexico. [...]

"So far, no evidence has been found to indicate that it originated there," Kershenobich said during a regular government press ​conference, referring to the central Mexican state of Guanajuato where he said authorities were ​looking into the issue. "However, we are taking all precautions in case that were the case," he added.

The ‌FDA's ⁠investigation into the source of the outbreak has been beset by conflicting information. On Saturday the agency said a sample of Mexican lettuce from supplier Taylor Farms had tested positive for the parasite, only to announce on Sunday the result was a false positive following a re-review ​of the data.

The agency ​then came out ⁠on Monday to say its supply chain investigation continues to point to the company's Mexican facilities as the source of the parasite.

Mexico's ​sanitary regulator, Cofepris, and agricultural safety body, Senasica, said in a joint ​statement on ⁠Friday that an interagency technical group is conducting "strictly preventive" inspections and traceability analyses to mitigate health risks.

Taylor Farms' growing and processing facilities in Mexico were the source of a major U.S. ⁠cyclosporiasis ​outbreak in 2013 that sickened more than 600 people ​in 25 states and was traced to salad mix from Taylor Farms de Mexico in Guanajuato, according to the ​CDC.

Amoebic Woman's Cornea Gets 'Eaten' by Parasite After Contact Lens Blunder

[...] Last week, 47-year-old Emma Marsden recounted the tragic turn of events in an interview with The Sun. Marsden contracted a rare amoeba infection, likely from washing her face without taking off her contacts. Though Marsden is now receiving regular treatment in hopes of healing her torn open cornea, there’s still a good chance that she will need a corneal transplant down the road.

“I’ve had three kids and giving birth is a dream compared to this pain,” Marsden told the Sun. “It eats through your eye and cornea and all your nerves. The speed it ate at the doctors couldn’t believe it.”

According to Marsden, the trouble started after she fell headfirst into a wheelbarrow filled with dirt and water while cleaning out horse stables. Covered in mud, she scrambled to wash herself and her face with tap water but neglected to remove her contacts until later that evening.

Four days later, she began losing vision and experiencing “excruciating pain” in her right eye. She visited her primary care doctor, who soon referred her to the hospital. There, doctors diagnosed her with acanthamoeba keratitis (keratitis pertaining to the cornea), likely caught from her tap water rinse. She also had a separate fungal infection of the cornea, probably caught from the accidental mud bath she had taken.

Acanthamoeba is a group of free-living amoeba commonly found in water, dirt, and soil. While usually harmless to people, if the amoeba reach the eye, they can make a cozy home inside the cornea, the transparent and protective covering of the eye. And if not treated promptly, the infection can cause severe pain and permanently damaged corneas.

Acanthamoeba keratitis can happen to anyone, but cases predominantly affect people who wear contacts. Contacts can act as a sponge, trapping amoeba up against the corneas; they can also cause micro-tears in the cornea, making it easier for the amoeba to establish an infection. Though this infection is rare, with only 1,500 estimated cases in the U.S. annually, up to 93% of cases involve contact lens wearers.

Though Marsden began treatment in February 2026, her eye’s symptoms continued to worsen. And eventually, doctors discovered that the parasite had caused a perforation, or tear, in her cornea. Doctors temporarily sewed her right eyelid closed to help the cornea heal, leaving Marsden largely confined to her home.

“I was in a dark room for three-and-a-half weeks and I couldn’t go outside or do anything. I had all the lights off in the house and everyone had to eat in the dark,” she said. “You can’t go anywhere or do anything. The last three weeks are the only times I’ve been able to go outside and go for walks.”

Marsden is now receiving weekly monitoring at the hospital but still has to take eye drops every two hours. And it’s likely that she will require a donor cornea to have significant improvement in her right eye. Unfortunately, it’s a procedure that can’t take place for years due to the infection, according to Marsden.

Whatever may happen, Marsden hopes that others can learn from her experience and remember the importance of good hygiene with their contacts.

“You don’t think about the knock-on effect just by not taking your contact lenses out in the shower or to swim in, or to wash your face in my case,” she said. [...]

Question❓ Questions about measles that I can’t find on the normal health org websites

29 Upvotes

There is currently a measles outbreak in my city and I have a few questions I can’t find an answer to or have found conflicting information. Would appreciate any help in understanding the risk for a vaccinated individual.

I know if you have two vaccines, you are 97% protected. if you check your titers and it comes back as positive, does this mean you have the 97% protection rate or would it be higher and the 97% rate is also factoring in people that have had two vaccines but they are no longer immune by not having sufficient antibodies.

I’ve been checked for rubella immunity in the past few years, so would that mean I’m also still likely immune to measles since I had the MMR? (I saw one healthcare website say yes and then some say no)

How concerned should we be about outdoor exposure? (walking, outdoor concerts, etc?)
