A recall of ready-to-eat meat and poultry items made by BrucePac has been expanded to include nearly 1.8 million pounds of additional products, for a total of more than 11.7 million pounds of products recalled over possible listeria contamination, the US Department of Agriculture’s Food Safety and Inspection Service says.

The products were distributed to restaurants and institutions nationwide, including ready-to-eat items that are “on store shelves or in consumers’ refrigerators or freezers,” the agency says. It has released a preliminary list of schools that received the products in Delaware, Florida, Georgia, Illinois, Indiana, Iowa, Kentucky, Michigan, Missouri, New Jersey, New York, Ohio, Pennsylvania, Tennessee, West Virginia, Wisconsin and the District of Columbia.

The Food Safety and Inspection Service discovered the issue during routine product testing of finished poultry products, the agency said. BrucePac ready-to-eat chicken was identified as the source of the listeria bacteria, which may have affected other ready-to-eat meat and poultry items that were produced in Durant, Oklahoma, from May 31 to October 8.
