At Least 9 Dead In Listeria Outbreak, Largest In U.S. In Over A Decade

At least nine people have died after being infected with listeria from Boar’s Head deli meats tied to a massive recall last month, federal health officials said Wednesday.

The new food poisoning toll includes two deaths in South Carolina plus one each in Florida, New Mexico, Tennessee and New York, the U.S. Centers for Disease Control and Prevention said. Three deaths were previously confirmed in people who lived in Illinois, New Jersey and Virginia.

At least 57 people have been sickened and hospitalized in the outbreak. Illnesses were reported starting in late May and have continued into August, the agency said. It is the largest listeria outbreak in the U.S. since 2011, and Boar’s Head has recalled more than 7 million pounds of deli products.

Listeria infections are caused by a hardy type of bacteria that can survive and even thrive during refrigeration. An estimated 1,600 people get listeria food poisoning each year and about 260 die, according to the CDC. Infections can be hard to pinpoint because symptoms may occur quickly — or up to 10 weeks after eating contaminated food.

The infections are especially dangerous for older people, those who are pregnant or those with weakened immune systems.

The problem was discovered when a Boar’s Head liverwurst sample collected by health officials in Maryland tested positive for listeria. Further testing showed that the type of bacteria was the same strain causing illnesses in people.

Boar’s Head officials originally recalled liverwurst and other products meant to be sliced in retail delis with sell-by dates from July 25 to Aug. 30. On July 29, the recall was expanded to include all foods produced at the firm’s plant in Jarratt, Virginia. The products included those sliced at
