WASHINGTON – RBR Meat Company, Inc. launched a recall of approximately 21,220 lbs. of its frozen pizza product that may be adulterated with Listeria monocytogenes, the Food Safety and Inspection Service (FSIS) of the US Dept. of Agriculture reported.

The Vernon, California-based company discovered the problem during routine sampling. There have been no confirmed reports of adverse reactions due to consumption of the products.

The supreme frozen pizza item was produced on Feb. 23. The following product is subject to recall:

• 50.6-oz. corrugated box containing 1 shrink wrapped 16” pizza labeled as “Marketside Extra Large Supreme Pizza,” with lot code 20547.

The products bear establishment number “EST. 1821” inside the USDA mark of inspection. RBR Meat Company shipped the items to retail distribution centers in California, Nevada, Utah and Washington.

Consumption of food contaminated with L. monocytogenes can cause listeriosis, a serious infection that primarily affects older adults, persons with weakened immune systems, and pregnant women and their newborns. Less commonly, persons outside these risk groups are affected.

FSIS and RBR Meat Co. are concerned that some product may be frozen in consumers’ freezers.
