A single ingredient from a single dairy supplier has triggered one of the broadest food recall cascades in recent U.S. history — touching Zapp's and Dirty brand potato chips, Ghirardelli powdered beverage mixes, specialty snack mixes, cheese curds, pork rinds, and dozens more products sold at Walmart, Target, Kroger, Publix, Costco, and grocery stores across the country.
The source is a voluntary recall of bulk powdered milk and buttermilk by California Dairies Inc., a major agricultural cooperative that supplies approximately 40% of the U.S. market for dried milk powder. When California Dairies recalled more than 100 batches of its product on April 20, 2026, citing potential Salmonella contamination, every food manufacturer that had incorporated that ingredient into a seasoning, coating, mix, or finished product was affected.
