On Jul. 26, 2024, the Maryland Department of Health advised consumers not to eat certain deli meats produced by Boar’s Head because of potential contamination with Listeria bacteria.

A sample collected by the Department tested positive for Listeria monocytogenes. In collaboration with the Baltimore City Health Department, the Department collected an unopened liverwurst product from a retail store for testing as part of an outbreak investigation of Listeria monocytogenes infections. Whole genome sequencing results showed that a liverwurst sample collected by the Maryland Department of Health tested positive for the outbreak strain of Listeria monocytogenes.

Marylanders were advised to avoid Boar’s Head ready-to-eat liverwurst products produced between June 11 and July 17, 2024. Anyone concerned about an illness should contact a health care provider.
