A listeria outbreak tied to Boar’s Head deli meats has resulted in nine deaths and 57 hospitalizations across 18 states, health officials reported Thursday. The U.S. Centers for Disease Control and Prevention (CDC) confirmed the outbreak, which began in mid-July, has expanded to include 14 new cases and six additional fatalities.

The outbreak has been linked to deli meats, particularly Boar’s Head liverwurst and products sliced at retail delis. Investigations revealed that the bacteria Listeria Monocytogenes was found on equipment used for slicing meats, including the Boar’s Head Strassburger Brand Liverwurst. Contamination can occur in refrigerated environments and spread easily among equipment and surfaces.

The recall, which covers products sold nationwide, includes Boar’s Head Ready-to-Eat Liverwurst produced between June 11 and July 17, 2024. Affected items have sell-by dates from July 25 to August 30, 2024. The recall also includes prepackaged and sliced deli products from the affected establishment. Consumers are advised to check for “EST. 12612” or “P-12612” on product labels.

Health officials urge consumers to avoid eating recalled deli meats and to thoroughly clean refrigerators and surfaces that may have come into contact with these products. Those at higher risk for listeriosis, including pregnant individuals, the elderly, and those with weakened immune systems, are advised to heat deli meats to an internal temperature of 165 degrees Fahrenheit to kill any potential bacteria.

The CDC noted that the true number of cases may be higher, as some individuals recover without medical attention and are not tested for listeria. The outbreak is ongoing, with delays in reporting potential further cases.

Boar’s Head has expressed regret over the situation, emphasizing their commitment to food safety and the well-being of their consumers.
