The recall, upgraded on June 24, is due to potential Salmonella contamination originating from a dry milk powder seasoning ingredient supplied by a third party. Affected products have best-by dates ranging from July 27 through August 31, 2026, and can be identified by specific batch codes. Utz first issued a voluntary recall on April 28, acting out of caution despite initial seasoning tests returning negative results for Salmonella. Consumers who purchased the recalled chips are advised not to eat them and should discard them or return them for a refund; no illnesses have been reported to date.
