Sixty people were hospitalized and 10 are known to have died last year in the largest listeria outbreak since 2011.

The USDA said inspectors found product residue in the form of meat and fat from the equipment left over from the previous day.

According to a press release, a thorough review found multiple violations of food safety protocols — including the presence of mold, insects, and other unsanitary conditions — in the site of the outbreak at a Boar Head’s plant in Virginia to be the main cause of the outbreak.

Government inspectors documented unsanitary conditions at several Boar’s Head deli meat plants, not just the factory that was shut down last year after a deadly outbreak of listeria poisoning, federal records show.
