Herr's is recalling two types of potato chips due to a potential salmonella risk.

The company, based in Nottingham, Chester County, said the voluntary recall was for smoked chipotle flavored kettle cooked potato chips, a Herr's brand product, and for the smoke dried chipotle flavored kettle cooked potato chips under the Peddler's Pantry brand.

Those chips were flavored with a chipotle seasoning that contained a milk ingredient that is being recalled due to possible salmonella contamination, Herr's said.

No tests have confirmed the potential salmonella and no illnesses associated with the chips have been reported.
