Millions of pounds of ready-to-eat chicken and turkey products sold at places like Aldi, Kroger, Trade Joe’s and Walmart, have been recalled.

Last week’s nationwide recall of ready-to-eat meat and poultry has expanded to nearly 12 million pounds and now includes products sent to U.S. schools, restaurants, and several major retailers.

The nationwide recall includes more than 500 types of frozen waffles sold at Target, Walmart and other grocery chains.
