A recall of Utz potato chips has been elevated to the highest level by the Food and Drug Administration due to concerns of potential salmonella contamination. This classification is used when there is a reasonable probability of serious adverse health consequences or death from using a product.

The recall affects some Dirty and Zapp's brand chips. The FDA's weekly enforcement report shows the recall has been classified as a Class 1 designation, but does not provide further explanation for this classification.

Further details on the recall are available from the FDA, including the reason for the classification and the initial voluntary recall by Utz in May.
