Listeriosis, the illness caused by the bacteria, presents symptoms such as fever, muscle aches, nausea, abdominal pain, and diarrhea.
It poses a significant risk to individuals aged 65 and older, those with weakened immune systems, and pregnant women. In severe cases, it can lead to debilitating headaches, confusion, seizures, or loss of balance.
Health officials urge anyone experiencing these symptoms after consuming the recalled prepared meals, whether frozen or ready-to-eat, to contact a healthcare provider immediately.
Federal health agencies and public health officials have been investigating Listeria monocytogenes infections since August 2024 linked to the prepared meals.
So far, the Centers for Disease Control and Prevention (CDC) reports 27 cases across 18 states, with six deaths.
Listeria bacteria are found in the environment and can spread from contaminated food to surfaces. Listeria can grow on foods kept in the refrigerator for several days.
To prevent Listeriosis infection:
- Avoid unpasteurized (raw) milk or foods made from unpasteurized milk.
- Thoroughly cook raw meat, such as beef, pork, or poultry.
- Wash raw vegetables thoroughly before eating.
- Keep uncooked meats separate from vegetables and from cooked foods and ready-to-eat foods.
- Wash hands, knives, and cutting boards after handling uncooked foods.
