Listeria found in Walmart meatball meals may be linked to deadly fettuccine outbreak

Federal health officials are warning consumers not to eat certain heat-and-eat beef meatball pasta meals sold at Walmart stores because they may be contaminated with listeria bacteria previously linked to a deadly outbreak .

The U.S. Agriculture Department issued a public health alert late Thursday for Marketside Linguine with Beef Meatballs & Marinara Sauce sold in refrigerated 12-ounce clear plastic trays. The products have best-by dates of Sept. 22 through Oct. 1 and may still be in consumer's refrigerators.
