More than 200 companies use PCA's peanut butter and paste as ingredients. Pantry staples including cookies, crackers, cereal and candy are potentially contaminated. And ice cream's in trouble too.
The good news is that most major brands of jarred peanut butter sold in supermarkets aren’t affected. And only certain batches of plain-old peanuts are suspected carriers.
