A California-based company recalled 21,200 pounds of frozen pizzas that were sold at Walmart after a sample of Marketside Extra Large Supreme Pizza tested positive for the food poisoning bacteria Listeria monocytogenes.
They were sold in California, Colorado, Nevada, Washington state, Idaho, Montana, Oregon, Utah, Wyoming, Alaska, and Hawaii.
The pizzas came in a 50.6-oz. cardboard box containing a single shrink-wrapped 16-inch pizza. It was labeled with Lot Code #20547 and produced on February 23, 2017 by RBR Meat Company Inc.
Anyone who experiences flu-like symptoms within two months of eating this product should seek emergency medical attention.
No illnesses were reported as of March 15, but some people keep frozen pizzas for years. The “Best-Before” date is August 22, 2017.
Listeria can take up to 70 days to cause symptoms. It can survive in a freezer and grow in a refrigerator. Cooking the pizza to 150ºF should be enough to kill Listeria, but bacteria may survive if the food heats unevenly, a common problem in microwaves.
Food poisoning with Listeria can cause fever, muscle aches, headache, stiff neck, confusion, loss of balance, or seizures. These symptoms may come after diarrhea or intestinal symptoms.
Pregnant women may not have any symptoms of Listeria, but suffer a miscarriage, premature delivery, stillbirth, or deliver a baby that is born with a life-threatening Listeria infection.
