March 17 (UPI) -- A California meat company recalled 10 tons of frozen pizza because of possible listeria contamination, the U.S. Department of Agriculture announced.
About 21,220 pounds of pizzas shipped by RBR Meat Company Inc. of Vernon, Calif., to retailers in California, Nevada, Utah and Washington, are included in the recall. The products were produced on Feb. 23 and sold as 16-inch shrink-wrapped pizzas in 50.6 oz. corrugated boxes identified as "Marketside Extra Large Supreme Pizza," with a lot code of 20547. Within the USDA mark of inspection on a label is the phrase "EST. 1821."
The company discovered the problem during routine sampling of the product. A statement issued by the USDA's Food Safety and Inspection Service on Wednesday rated the health risk as "high" and warned customers not to consume the product. The agency suggested it should be discarded or returned to the place of purchase.
No adverse health reactions from eating the food have been reported.
The agency said the products could be contaminated by listeria monoctyogenes, bacteria which can cause listeriosis, an infection which can cause fever, headaches, loss of balance and convulsions. Listeriosis is generally caused by eating contaminated food and can spread beyond the gastrointestinal tract to cause birth defects and deaths in those with weakened immune systems.
