The Boar's Head deli-meat plant at the epicenter of a nationwide Listeria outbreak that killed nine people so far harbored the deadly germ in a common area of the facility deemed "low risk" for Listeria. Further, it had no written plans to prevent cross-contamination of the dangerous bacteria to other products and areas. That's according to a federal document newly released by Boar's Head.

On Friday, the company announced that it is indefinitely closing that Jarratt, Virginia-based plant and will never again produce liverwurst—the product that Maryland health investigators first identified as the source of the outbreak strain of Listeria monocytogenes. The finding led to the recall of more than 7 million pounds of Boar's Head meat. The Jarratt plant, where the company's liverwurst is made, has been shuttered since late July amid the investigation into how the outbreak occurred.

In the September 13 update, Boar's Head explained that "our investigation has identified the root cause of the contamination as a specific production process that only existed at the Jarratt facility and was used only for liverwurst. With this discovery, we have decided to permanently discontinue liverwurst."

The outbreak of H5N1 bird flu in US dairy cows has now spread to three herds in California, the largest milk-producing state in the country, with around 1.7 million dairy cows, federal and state health officials have confirmed.

Fourteen states and 197 herds have now been affected by the unprecedented outbreak in dairy cows, which was first confirmed by federal health officials on March 25.

In a statement, the secretary of the California Department of Food and Agriculture, Karen Ross, said the spread of the virus to California was not unexpected. "We have been preparing for this possibility since earlier this year when [Highly pathogenic avian influenza or HPAI] detections were confirmed at dairy farms in other states," Ross said. "Our extensive experience with HPAI in poultry has given us ample preparation and expertise to address this incident, with workers’ health and public health as our top priorities."

Federal inspections found 69 violations—many grisly—at the Boar's Head meat facility at the center of a deadly, nationwide Listeria outbreak that has now killed nine people, sickened and hospitalized a total of 57 across 18 states, and spurred the nationwide recall of more than 7 million pounds of meat.

The Jarratt, Virginia-based facility had repeated problems with mold, water leaks, dirty equipment and rooms, meat debris stuck on walls and equipment, various bugs, and, at one point, puddles of blood on the floor, according to inspection reports from the US Department of Agriculture's Food Safety and Inspection Services. The reports were obtained by CBS News through a Freedom of Information Act Request. In all, the reports outline 69 violations just between the dates of August 1, 2023, and August 2, 2024.

The findings in the reports reveal the perfect conditions for the company's meat to become contaminated with the germ behind the deadly outbreak, Listeria monocytogenes. This is a hardy germ that is ubiquitous in the environment, including in soil and water, and it spreads among people via the fecal-oral route. In healthy people, it usually only causes gastrointestinal infections. But for older people, newborns, and the immunocompromised, it can cause a life-threatening invasive infection with a fatality rate of around 17 percent. It's also a significant danger to pregnant people, causing miscarriage, stillbirth, premature delivery, and life-threatening infections in newborns.

A third person has died in a nationwide bacterial outbreak linked to Boar's Head brand deli meats. Last week, the company recalled more than 7 million pounds of its meats, which was in addition to a recall of over 200,000 pounds of meat from July 26. In all, 71 types of products made between May 10, 2024, and July 29, 2024, and sold nationwide have been recalled.

According to an update Thursday from the Centers for Disease Control and Prevention, the outbreak has now sickened a total of 43 people, an increase from 34 last week. There have been 43 hospitalizations, up from 33 last week. The illnesses are reported from 13 states. The three deaths in the outbreak include one from Illinois and one from New Jersey, and the newly reported death is from Virginia. The CDC expects the tally of illnesses so far to be a significant undercount of actual cases, and additional states may be affected.

The illnesses in the outbreak are caused by Listeria monocytogenes, a foodborne bacterium that is particularly dangerous to people who are pregnant, people age 65 years or older, and people who have weakened immune systems. In these high-risk groups, the bacteria are more likely to move beyond the gastrointestinal system to cause an invasive infection called listeriosis. During pregnancy, listeriosis can cause miscarriage, stillbirth, premature delivery, or a life-threatening infection in newborns. For non-pregnant people who develop listeriosis, nearly 90 percent require hospitalization, and 1 in 6 die.

Over 7 million pounds of Boar's Head brand deli meats are being recalled amid a bacterial outbreak that has killed two people. The outbreak, which began in late May, has sickened a total of 34 people across 13 states, leading to 33 hospitalizations, according to the US Department of Agriculture.

On June 26, Boar's Head recalled 207,528 pounds of products, including liverwurst, beef bologna, ham, salami, and "heat and eat" bacon. On Tuesday, the Jarratt, Virginia-based company expanded the recall to include about 7 million additional pounds of meat, including 71 different products sold on the Boar's Head and Old Country brand labels. The products were sold nationwide.

The meats may be contaminated with Listeria monocytogenes, a foodborne pathogen that is particularly dangerous to pregnant people, people over the age of 65, and people with compromised immune systems. Infections during pregnancy can cause miscarriage, stillbirth, premature delivery, or a life-threatening infection in newborns. For others who develop invasive illness, the fatality rate is nearly 16 percent. Symptoms of listeriosis can include fever, muscle aches, headache, stiff neck, confusion, loss of balance, and convulsions that are sometimes preceded by diarrhea or other gastrointestinal symptoms.

A second Colorado poultry farm has reported a case of bird flu in a worker, marking the state's seventh human case this month amid the ongoing outbreak among dairy cows.

Colorado health officials said the seventh case is, for now, a presumptive positive. That means that the person has tested positive at the state level while confirmatory testing is being carried out at the Centers for Disease Control and Prevention.

The presumptive positive worker was at a poultry facility in the state's northeastern Weld County. In recent weeks, six workers at another poultry farm in Weld also tested positive for bird flu. In that facility, a commercial egg layer operation with about 1.8 million birds, workers were infected as they culled chickens known to be infected with the highly pathogenic avian influenza. Genetic testing of the virus in the birds and the workers indicated that they were infected with a strain of H5N1 closely related to the virus found spreading in dairy cattle and to dairy farm workers.

The highly pathogenic avian influenza H5N1 virus that spilled from wild birds into US dairy cows late last year may have recently seeped from a dairy farm in Colorado to a nearby poultry farm, where it then infected five workers tasked with culling the infected chickens

In a press briefing Tuesday, federal officials reported that four of the avian influenza cases have been confirmed by the Centers for Disease Control and Prevention, while the fifth remains a presumptive positive awaiting CDC confirmation.

All five people have shown mild illnesses, though they experienced variable symptoms. Some of the cases involved conjunctivitis, as was seen in other human cases linked to the H5N1 outbreak in dairy cows. Others in the cluster of five had respiratory and typical flu-like symptoms, including fever, chills, sore throat, runny nose, and cough. None of the five cases required hospitalization.

The US government will pay Moderna $176 million to develop an mRNA vaccine against a pandemic influenza—an award given as the highly pathogenic bird flu virus H5N1 continues to spread widely among US dairy cattle.

The funding flows through BARDA, the Biomedical Advanced Research and Development Authority, as part of a new Rapid Response Partnership Vehicle (RRPV) Consortium. The program is intended to set up partnerships with industry to help the country better prepare for pandemic threats and develop medical countermeasures, the Department of Health and Human Services said in a press announcement Tuesday.

In its own announcement on Tuesday, Moderna noted that it began a Phase 1/2 trial of a pandemic influenza virus vaccine last year, which included versions targeting H5 and H7 varieties of bird flu viruses. The company said it expects to release the results of that trial this year and that those results will direct the design of a Phase 3 trial, anticipated to begin in 2025.

Four backyard alpacas in southern Idaho have tested positive for highly pathogenic avian influenza (HPAI) H5N1, marking the first time bird flu has been detected in members of the fleecy camelid family, according to the US Department of Agriculture.

On Tuesday, the USDA announced that the agency's National Veterinary Services Laboratories confirmed the infection on a farm in Jerome County on May 16. While the infections are a first for the spitting llama relatives, the USDA said they weren't particularly surprising. The alpacas were in close contact with HPAI-infected poultry on the farm, which were "depopulated" this month. Of 18 alpacas on the affected farm, only four were found to be infected. There were no deaths documented, according to a report the USDA submitted to the World Organization for Animal Health.

Genomic sequencing indicates that the H5N1 virus infecting the alpacas (B3.13) matches both the virus currently circulating among US dairy cows and the virus that infected birds on the farm.

Despite the delusions of the raw milk crowd, drinking unpasteurized milk brimming with infectious avian H5N1 influenza virus is a very bad idea, according to freshly squeezed data published Friday in the New England Journal of Medicine.

Researchers at the University of Wisconsin-Madison squirted raw H5N1-containing milk from infected cows into the throats of anesthetized laboratory mice, finding that the virus caused systemic infections after the mice were observed swallowing the dose. The illnesses began quickly, with symptoms of lethargy and ruffled fur starting on day 1. On day 4, the animals were euthanized to prevent extended suffering. Subsequent analysis found that the mice had high levels of H5N1 bird flu virus in their respiratory tracts, as well their hearts, kidneys, spleens, livers, mammary glands, and brains.

"Collectively, our data indicate that HPAI [Highly Pathogenic Avian Influenza] A(H5N1) virus in untreated milk can infect susceptible animals that consume it," the researchers concluded. The researchers also found that raw milk containing H5N1 can remain infectious for weeks when stored at refrigerator temperatures.
