HVP Salmonella recall adding more companies, products

At least eight more companies, including McCormick's, have recalled their products since the U.S. Food and Drug Administration acknowledged on Friday that an obscure ingredient, Hydrolyzed Vegetable Protein, could be tainted with Salmonella -- creating a chain-reaction of recalls of foods using the flavor-enhancer.

HVP is similar to Monosodium Glutamate (MSG) and can lead to similar issues for those sensitive to MSG, including headaches. Salmonella was discovered in the Las Vegas plant of Basic Food Flavors, a major HVP supplier.
