Texas official warns against “measles parties” as outbreak keeps growing

Cook, along with Lubbock’s director of public health, Katherine Wells, said they see no end in sight for the outbreak, which now spans nine counties in Texas, many of which have low vaccination rates. “This outbreak is going to continue to grow,” Wells said, declining to forecast how high the final case count could go after a reporter raised the possibility of several hundred.

So far, 116 of the 146 cases are under the age of 18, with 46 being between the ages of 0 and 4. Only five of the 146 were vaccinated with at least one dose of the Measles, Mumps, and Rubella (MMR) vaccine.

Messaging

On a more positive note, Wells reported that the outbreak has seemed to sway some vaccine-hesitant parents to get their children vaccinated. Just yesterday in Lubbock, over 50 children came into the city’s clinic for measles vaccines. Eleven of those children had vaccine exemptions, meaning their parents had previously gone through the state process to exempt their child from having to receive routine childhood vaccines to attend school. “Which is a really good sign; that means our message is getting out there,” Wells said.

So far in the outbreak, which erupted in late January, messaging about the disease and the importance of vaccination has exclusively come from state and local authorities. The Centers for Disease Control and Prevention only released a brief statement late Thursday, which was not sent through the agency’s press distribution list. It did, however, note that “vaccination remains the best defense against measles infection.”

During a cabinet meeting Wednesday, US Health Secretary and anti-vaccine advocate Robert F. Kennedy Jr. responded to a question about the outbreak, offering a variety of inaccurate information. Kennedy downplayed the outbreak, falsely claiming that “it’s not unusual.” But, this is an unusual year for measles in the US. As epidemiologist Katelyn Jetelina noted on Bluesky, the number of US measles cases this year has already surpassed the total case counts from eight of the previous 15 years. And it is only February.

Trump admin. fires USDA staff working on bird flu, immediately backpedals

Over the weekend, the Trump administration fired several frontline responders to the ongoing H5N1 bird flu outbreak—then quickly backpedaled, rescinding those terminations and attempting to reinstate the critical staff.

The termination letters went out to employees at the US Department of Agriculture, one of the agencies leading the federal response to the outbreak that continues to plague US dairy farms and ravage poultry operations, affecting over 160 million birds and sending egg prices soaring. As the virus continues to spread, infectious disease experts fear it could evolve to spread among humans and cause more severe disease. So far, the Centers for Disease Control and Prevention has documented 68 cases in humans, one of which was fatal.

Prior to Trump taking office, health experts had criticized the country’s response to H5N1 for lack of transparency at times, sluggishness, inadequate testing, and its inability to halt transmission among dairy farms, which was once considered containable. To date, 972 herds across 17 states have been infected since last March, including 36 herds in the last 30 days.

In a statement to Ars Technica, a USDA spokesperson said that the agency views the response to the outbreak of H5N1—a highly pathogenic avian influenza (HPAI)—as a priority. As such, the agency had protected some positions from staff cuts by granting exemptions, which went to veterinarians, animal health technicians, and others. But not all were exempted, and some were fired.

“Although several positions supporting HPAI were notified of their terminations over the weekend, we are working to swiftly rectify the situation and rescind those letters,” the spokesperson said.

The USDA did not respond to Ars Technica’s questions regarding how many employees working on the outbreak were fired, how many of those terminations were rescinded, or how many employees have been reinstated since the weekend.

The cuts are part of a larger, brutal effort by the Trump administration to slash federal agencies, and the cuts have imperiled other critical government and public services. In recent days, several agencies, including the National Institutes of Health, the CDC, the National Science Foundation, and the Department of Energy, among others, have been gutted. At CDC, cuts devastated the agency’s premier disease detectives program—the Epidemic Intelligence Service—members of which are critical to responding to outbreaks and other health emergencies.

Measles outbreak in undervaccinated Texas area doubles—again

A measles outbreak in an area of Texas with abysmal vaccination rates continues to mushroom, with cases doubling since Tuesday and expanding into additional counties.

A week ago, officials reported nine confirmed cases in Gaines County, at the border of New Mexico, which has one of the lowest vaccination rates among kindergartners in the state at just about 82 percent. On Tuesday, the cases climbed to 24, all in Gaines. In Friday’s update, the state health department reports that the case count has now reached 48 and spread to three nearby counties, which also have vaccination rates below the 95 percent threshold that prevent vaccine-preventable diseases from spreading onward.

Gaines now reports 42 cases. There’s one case reported in Lynn County to the northeast, which has a 91 percent vaccination rate. Terry County, with a vaccination rate of 94 percent, reports three cases, and Yoakum County, with a vaccination rate of 92.5 percent, reports two cases. Terry and Yoakum are both directly north of Gaines.

As before, all cases are in unvaccinated people or people with unknown vaccination status. Of the 48 cases, 42 are in children, including 13 between the ages of 0 and 4. Thirteen people (27 percent) have been hospitalized.

Nine unvaccinated people hospitalized as Texas measles outbreak doubles

In an interview with Ars Technica last week, Zach Holbrooks, the executive director of the South Plains Public Health District (SPPHD), which includes Gaines, said that the area has a large religious community that has expressed vaccine hesitancy.

Additional cases likely

Pockets of the county have yet lower vaccination rates than the county-wide averages suggest. For instance, one independent public school district in Loop, in the northeast corner of Gaines, had a vaccination rate of 46 percent in the 2023–2024 school year.

Measles is one of the most infectious diseases known. The measles virus spreads through the air and can linger in the airspace of a room for up to two hours after an infected person has left. Ninety percent of unvaccinated people who are exposed will fall ill with the disease, which is marked by a very high fever and a telltale rash. Typically, 1 in 5 unvaccinated people with measles in the US end up hospitalized, and 1 in 20 develop pneumonia. Between 1 to 3 in 1,000 die of the infection. In rare cases, it can cause a fatal disease of the central nervous system called Subacute sclerosing panencephalitis later in life. Measles can also wipe out immune responses to other infections (a phenomenon known as immune amnesia), making people vulnerable to other infectious diseases.

“Due to the highly contagious nature of this disease, additional cases are likely to occur in Gaines County and the surrounding communities,” the state health department said.

While Gaines is remarkable for its low vaccination rate, vaccination coverage nationwide has slipped in recent years as vaccine misinformation and hesitancy have taken root. Overall, vaccination rates among US kindergartners have fallen from 95 percent in the 2019–2020 school year into the 92 percent range in the 2023–2024 school year. Vaccine exemptions, meanwhile, have hit an all-time high. Health experts expect to see more vaccine-preventable outbreaks, like the one in Gaines, as the trend continues.

Bird flu strain that just jumped to cows infects dairy worker in Nevada

However, the new Nevada case is notable because it marks the first time D1.1 is known to have jumped from birds to cows to a person. Moreover, D1.1 has proven dangerous. The genotype is behind the country’s only severe and ultimately fatal case of H5N1 so far in the outbreak. The death in the Louisiana case linked to wild and backyard birds was reported last month. The CDC’s statement added that the person had “prolonged, unprotected” exposure to the birds. The D1.1. genotype was also behind a severe H5N1 infection that put a Canadian teenager in intensive care late last year.

In a February 7 analysis, the USDA reported finding that the D1.1 strain infecting cows in Nevada has a notable mutation known to help the bird-adapted virus replicate in mammals more efficiently (PB2 D701N). To date, this mutation has not been seen in D1.1 strains spreading in wild birds nor has it been seen in the B3.13 genotype circulating in dairy cows. However, it was seen before in a 2023 human case in Chile. The CDC said it has confirmed that the strain of D1.1 infecting the person in Nevada also contains the PB2 D701N mutation.

The USDA and CDC both reported that no other concerning mutations were found, including one that has been consistently identified in the B3.13 strain in cows. The CDC said it does not expect any changes to how the virus will interact with human immune responses or to antivirals.

Most importantly, to date, there has been no evidence of human-to-human transmission, which would mark a dangerous turn for the virus’s ability to spark an outbreak. For all these reasons, the CDC considers the risk to the public low, though people with exposure to poultry, dairy cows, and birds are at higher risk and should take precautions.

To date, 967 herds across 16 states have been infected with H5N1 bird flu, and nearly 158 million commercial birds have been affected since 2022.

H5N1 bird flu spills over again; Nevada cows hit with different, deadly strain

The spread of H5N1 bird flu in dairy cows is unprecedented; the US outbreak is the first of its kind in cows. Virologists and infectious disease experts fear that the continued spread of the virus in domestic mammals like cows, which have close interactions with people, will provide the virus countless opportunities to spill over and adapt to humans.

So far, the US has tallied 67 human cases of H5N1 since the start of 2024. Of those, 40 have been in dairy workers, while 23 were in poultry workers, one was the Louisiana case who had contact with wild and backyard birds, and three were cases that had no clear exposure.

Whether the D1.1 genotype will pose a yet greater risk for dairy workers remains unclear for now. Generally, H5N1 infections in humans have been rare but dangerous. According to data collected by the World Health Organization, 954 H5N1 human cases have been documented globally since 2003. Of those, 464 were fatal, for a fatality rate among documented cases of 49 percent. But, so far, nearly all of the human infections in the US have been relatively mild, and experts don’t know why. There are various possible factors, including transmission route, past immunity of workers, use of antivirals, or something about the B3.13 genotype specifically.

For now, the USDA says that the detection of the D1.1 genotype in cows doesn’t change their eradication strategy. It further touted the finding as a “testament to the strength of our National Milk Testing Strategy.”

Biofilms, unwashed hands: FDA found violations at McDonald’s ex-onion supplier

Perhaps most concerning, FDA inspectors noted that employees were never seen washing their hands. Instead, they wore gloves, and if they touched dirty surfaces or items, they would simply put hand sanitizer on their dirty gloves and carry on. What they should have been doing was removing their dirty gloves, washing their hands, and getting clean gloves. However, the FDA inspectors never saw this happen, and managers confirmed that hand sanitizing gloves was common practice.

The inspectors also noted that the facility’s equipment was always wet. Employees applied sanitizing solutions on knives and other equipment used to dice and chop fresh produce. The sanitizing solution is meant to be air-dried before use, but Taylor Farms employees immediately used the equipment—still dripping with sanitizing solution—to cut RTE produce.

On one day of the inspection, FDA agents saw employees chop RTE lettuce with equipment that was wet with sanitizing solution at the maximum concentration, which was 200 ppm. In another instance, the inspectors saw an employee mix cleaning chemicals together to make a sanitizing solution, which the employee said was done “routinely.” When inspectors asked about the mixture, Taylor Farms “could not find the source of this recipe,” nor could they find the manufacturer label or other information stating the mixture was designed for use.

“Highest expectations”

In a statement to CBS, Taylor Farms said that it “immediately took steps to address” the problems found in the FDA’s inspection, which resulted in no “administrative or regulatory action” against the company.

“Taylor Farms is confident in our best-in-class food safety processes, and in turn, the quality and safety of our products,” the company said in the statement. “As is common following an inspection, FDA issued observations of conditions that could be improved at one of our facilities.” The company added that “no illnesses or public health threat has been linked to these observations” in the inspection.

McDonald’s, meanwhile, said it had stopped getting onions from the facility.

“We hold our suppliers to the highest expectations and standards of food safety. Prior to this inspection, and unrelated to its findings, McDonald’s stopped sourcing from Taylor Farms’ Colorado Springs facility,” McDonald’s said in a statement.

Teen in critical condition with Canada’s first human case of H5 bird flu

A British Columbia teen who contracted Canada’s first known human case of H5 bird flu has deteriorated swiftly in recent days and is now in critical condition, health officials reported Tuesday.

The teen’s case was announced Saturday by provincial health officials, who noted that the teen had no obvious exposure to animals that could explain an infection with the highly pathogenic avian influenza. The teen tested positive for H5 bird flu at BC’s public health laboratory, and the result is currently being confirmed by the National Microbiology Laboratory in Winnipeg.

The teen’s case reportedly began with conjunctivitis, echoing the H5N1 human case reports in the US. The case then progressed to fever and cough, and the teen was admitted to BC’s Children’s hospital late Friday. The teen’s condition varied throughout the weekend but had taken a turn for the worse by Tuesday, according to BC provincial health officer Bonnie Henry.

“This was a healthy teenager prior to this—so, no underlying conditions—and it just reminds us that in young people, this is a virus that can progress and cause quite severe illness,” Bonnie Henry said in a media briefing streamed by Global News on Tuesday.

Health officials in the province have opened an investigation to understand the source of the outbreak. Around three dozen contacts of the teen have been tested, and all have been negative. “The source of exposure is very likely to be an animal or bird and is being investigated by BC’s chief veterinarian and public health teams,” health officials noted in the announcement over the weekend. The teen was reportedly exposed to pets, including dogs, cats, and reptiles, but testing so far has been negative on them.

slivered-onions-are-likely-cause-of-mcdonald’s-e.-coli-outbreak,-cdc-says

Slivered onions are likely cause of McDonald’s E. coli outbreak, CDC says

Slivered onions are the likely source of the multi-state E. coli outbreak linked to McDonald’s Quarter Pounder burgers that continues to grow, the Centers for Disease Control and Prevention announced Wednesday.

Onions were one of two primary suspects when the CDC announced the outbreak on October 22, with the other being the beef patties used on the burgers. But onions quickly became the leading suspect. The day after the CDC’s announcement, McDonald’s onion supplier, Taylor Farms, recalled peeled and diced yellow onion products and several other fast food chains took onions off the menu as a precaution. (No other restaurants have been linked to the outbreak to date.)

According to the CDC, traceback information and epidemiological data collected since then have all pointed to the onions and, according to McDonald’s, state and federal testing of the beef patties has all come back negative.

In the CDC’s update Wednesday, the agency reported that 15 more people were identified as sickened in the outbreak, including five who were hospitalized. In all, that brings the outbreak to 90 cases, including 27 hospitalizations and one death, which collectively span 13 states.

All the newly reported illnesses had onsets prior to the October 23 onion recall. The most recent illness onset was October 16. Additional illnesses may be reported, as it can take three to four weeks to link illnesses to an outbreak.

“Due to the product actions taken by McDonald’s and Taylor Farms, the CDC believes the continued risk to the public is very low,” the agency said in a media alert.

McDonald’s says that Quarter Pounders—without onions—will return to the menus of affected restaurants this week. Prior to the recall, 900 restaurants had received onions from Taylor Farms, including in Colorado, Kansas, and Wyoming, as well as portions of Idaho, Iowa, Missouri, Montana, Nebraska, Nevada, New Mexico, Oklahoma, and Utah.

Person accidentally poisoned 46 coworkers with toxin-loaded homemade lunch

For some, microwaving fish in the employee lunch room is the ultimate work faux pas. But for one (likely mortified) employee of a seafood distribution plant in Maryland, it’s probably causing a mass poisoning with the homemade noodle dish they brought to share for lunch. The dish sickened 46 employees, spurring their employer to hastily release a statement assuring customers that it wasn’t the company’s food that caused the illnesses.

On October 21, first responders and paramedics arrived at the NAFCO Wholesale Fish Distribution Facility in Jessup, where dozens of employees had abruptly fallen ill about three hours after lunch. Helicopter footage of the event captured images of workers around picnic tables outside the plant, some doubled over and with their heads down.

Ultimately, 46 people were sickened, and at least 26 were treated at an area hospital with symptoms of food poisoning, according to The Baltimore Banner. They all recovered.

“NAFCO maintains the highest standards of food safety and regularly undergoes rigorous inspections by health authorities,” NAFCO said in a written statement. “Its products continue to be safely produced and consumed by customers nationwide, and there are no issues related to its supply chain.”

Enterotoxins

In an update on Tuesday, the Maryland Department of Health announced that testing found that Staphylococcus aureus was the cause of the illnesses. S. aureus is often thought of as a skin bacterium, but the pathogen can spread to food from unwashed hands, the Centers for Disease Control and Prevention notes. In food that isn’t thoroughly cooked or is held at warm temperatures (between 40° F and 140° F) conducive to bacterial growth, the germ can grow and produce toxins.

mcdonald’s-e.-coli-outbreak-grows-by-50%-in-3-days-as-lawsuits-mount

McDonald’s E. coli outbreak grows by 50% in 3 days as lawsuits mount

Twenty-six more cases have been identified in a multistate E. coli O157:H7 outbreak linked to McDonald’s Quarter Pounder burgers, the Centers for Disease Control and Prevention announced Friday.

The 26 new cases represent a 50 percent increase in the case count from October 22, bringing the total to 75 cases. With the new cases, health officials also reported 12 more hospitalizations, including one new adult case of hemolytic uremic syndrome (HUS), a severe complication to an E. coli O157:H7 infection. Three more states are also newly affected: Michigan, New Mexico, and Washington.

In all, the outbreak now stands at 75 cases, including 22 hospitalizations and two cases of HUS, across 13 states. The number of deaths linked to the outbreak remains at one. The most recent illness onset for the cases identified so far is October 10.

The states with cases now include: Colorado (26 cases), Montana (13), Nebraska (11), New Mexico (5), Utah (5), Missouri (4), Wyoming (4), and Michigan (2), and one case each in Iowa, Kansas, Oregon, Washington, and Wisconsin.

The source of the outbreak has not yet been confirmed, but investigators have focused on the beef patties and slivered onions used on McDonald’s Quarter Pounders. McDonald’s immediately pulled the popular burger off the menu and paused distribution of the slivered onions from affected restaurants when the CDC announced the outbreak Tuesday. McDonald’s considered the affected areas to be Colorado, Kansas, Utah, and Wyoming, as well as portions of Idaho, Iowa, Missouri, Montana, Nebraska, Nevada, New Mexico, and Oklahoma.

Onions recalled and destroyed

On Wednesday, one of McDonald’s onion suppliers, Taylor Farms, recalled peeled and diced yellow onion products. Taylor Farms told Bloomberg earlier this week that its testing had not turned up E. coli, but that it decided to issue the recall anyway.

Rare bear meat at gathering gives 10 people a scare—and parasitic worms

If you’re going to eat a bear, make sure it’s not rare.

You’d be forgiven for thinking that once the beast has been subdued, all danger has passed. But you might still be in for a scare. The animal’s flesh can be riddled with encased worm larvae, which, upon being eaten, will gladly reproduce in your innards and let their offspring roam the rest of your person, including invading your brain and heart. To defeat these savage squirmers, all one must do is cook the meat to at least 165° Fahrenheit.

But that simple solution continues to be ignored, according to a report today in the Centers for Disease Control and Prevention’s Morbidity and Mortality Weekly Report. In this week’s issue, health officials in North Carolina report that rare bear meat was served at a November 23 gathering, where at least 22 people ate the meat and at least 10 developed symptoms of a worm infection. Of the 10, six were kids and teens between the ages of 10 and 18.

The infection is from the roundworm Trichinella, which causes trichinellosis. While the infection is rarely fatal, the nematodes tend to burrow out of the bowels and meander through the body, embedding in whatever muscle tissue they come across. A telltale sign of an infection in people is facial swelling, caused when the larvae take harbor in the muscles of the face and around the eyes. Of the 10 ill people in North Carolina, nine had facial swelling.

Local health officials were onto the outbreak when one person developed flu-like symptoms and puzzling facial swelling. They then traced it back to the gathering. The report doesn’t specify what kind of gathering it was but noted that 34 attendees in total were surveyed, from which they found the 22 people who ate the rare meat. The 10 people found with symptoms are technically considered only “probable” cases because the infections were never diagnostically confirmed. To confirm a trichinellosis infection, researchers need blood samples taken after the person recovers to look for antibodies against the parasite. None of the 10 people returned for blood draws.
