Utz Quality Foods, LLC issued a voluntary recall in the US of certain varieties of Zapp's and Dirty potato chips in May after Utz learned that a seasoning used in the chips containing dry milk powder may contain the bacteria salmonella.

The dry milk powder was sourced from California Dairies, Inc. and supplied by an unspecified third-party vendor.

Last week, the FDA then upgraded the recall and classified it as a Class I, indicating 'a situation in which there is a reasonable probability that the use of or exposure to a violative product will cause serious adverse health consequences or death.'
