FDA issues most serious recall alert for potato chip brands over salmonella risk

An estimated 650,000 bags of potato chips are affected as US agency upgraded recall of several popular brands

The US Food and Drug Administration (FDA) has upgraded a recall of several popular brands of potato chips to its most serious level because of the risk of salmonella contamination.

Manufacturer Utz issued a voluntary recall in May for varieties of its Zapp's and Dirty potato chips products, citing the possible presence of salmonella in dry milk powder sourced from a third party used to make a seasoning ingredient.
