Two types of crackers were recently recalled due to Salmonella contamination from whey powder. While this was a voluntary recall by the whey powder supplier, it highlights another challenge in food manufacturing.
Crackers are baked and that heat will kill Salmonella. But the recalled crackers had a topping added after baking that contained the whey powder. Adding the whey after any baking or cooking has occurred, such as the application of seasoning powder, icing, or other topping components that include the whey powder can introduce pathogens such as Salmonella. Post-baking contamination has previously been associated with foodborne Salmonella outbreaks.
