Fresh & Ready Foods has recalled several ready-to-eat foods that don’t need extra cooking, including certain sandwiches and snacks, due to potential listeria monocytogenes contamination, according to a recall notice from the Food and Drug Administration (FDA).

Listeria can survive and grow in refrigerated food. It can be killed by heating foods to “steaming hot,” or 165 degrees Fahrenheit, the CDC says. But that’s not always possible — or palatable — for foods that are made to be eaten cold.

U.S. health officials say a listeria outbreak linked to ready-to-eat sandwiches and snacks has sickened at least 10 people.
