Utz Quality Foods is issuing a voluntary recall of certain potato chip varieties after concerns they may be contaminated with Salmonella. Multiple outlets report that the U.S. Food and Drug Administration announced the recall and that it covers specific Zapp’s and Dirty brand products sold nationwide. The recall is tied to a seasoning ingredient supplied by a third-party vendor, which Utz says may contain Salmonella. CBS News, Forbes, and other sources note that the affected products include particular flavors of Zapp’s chips and particular flavors of Dirty chips, with packaging sizes described in reporting (including 2-ounce bags for some Dirty products). The New York Post, The Hill, Mint, and the Washington Times characterize the action as a voluntary recall initiated in response to information about the potential contamination. The Guardian similarly reports that the concern involves seasoning used on the chips and that the FDA is involved in the notice. The reports consistently state that the recall is meant to reduce the risk of food-borne illness associated with Salmonella.
