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.
