Amid an outbreak of listeria that has killed two people in the United States and sickened around three dozen others, Boar’s Head Products announced on Friday that it would recall more than 200,000 pounds of deli meat, including all liverwurst products currently available on the market.

The announcement came after the U.S. Department of Agriculture said that it had detected listeria bacteria in an unopened package of Boar’s Head liverwurst from a Maryland store.

Boar’s Head also recalled several other types of deli meat that were made on the same day, June 27, and on the same production line as the tainted liverwurst.

The company said it had immediately recalled the liverwurst in question, and made a decision to “voluntarily recall additional products” out of an abundance of caution. “We are cooperating fully with government authorities and conducting our own investigation into this incident,” a spokeswoman for Boar’s Head said in a statement on Friday.

Boar’s Head recalled multi-pound loaves of “Strassburger Brand Liverwurst MADE IN VIRGINIA” with sell-by dates ranging from July 25 to August 30. It also recalled several other meats intended to be sliced by delis that were stamped with an Aug. 10 sell-by date, including: Virginia ham, Italian Cappy Ham, Extra Hot Italian Cappy Ham, Pork & Beef Bologna, Beef Salami, Beef Bologna and Garlic Bologna. Steakhouse Roasted Slab Bacon, with a sell-by date of Aug. 15, was also recalled.

The U.S.D.A. said in its statement that the products had been distributed to retail deli locations nationwide. (Here are the labels).
