New Jersey-based Jack Lambersky Poultry Company has halted operations and is voluntarily recalling 200,000 pounds of ready-to-eat chicken and turkey over concerns that it might be linked to a listeria outbreak.

Tests showed that a strain of listeria found in some of the meat matched a strain that sickened 50 people and killed seven in the northeastern US.

The USDA is urging consumers to check their refrigerators and freezers for the recalled products, a full list of which can be found on the Food Safety and Inspection Service’s website.
