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."

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.

Five more people have died in a nationwide outbreak of Listeria infections linked to contaminated Boar's Head brand meats, the Centers for Disease Control and Prevention reported Wednesday.

To date, 57 people across 18 states have been sickened, all of whom required hospitalization. A total of eight have died. The latest tally makes this the largest listeriosis outbreak in the US since 2011, when cantaloupe processed in an unsanitary facility led to 147 Listeria infections in 28 states, causing 33 deaths, the CDC notes.

The new cases and deaths come after a massive recall of more than 7 million pounds of Boar's Head meat products, which encompassed 71 of the company's products. That recall was announced on July 30, which itself was an expansion of a July 26 recall of an additional 207,528 pounds of Boar's Head products. By August 8, when the CDC last provided an update on the outbreak, the number of cases had hit 43, with 43 hospitalizations and three deaths.

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.
