How Salmonella Gets into Ice Cream
Salmonella can enter ice cream through contaminated raw eggs, milk, or cream. Poor sanitation during mixing, pasteurization failures, or cross-contamination from equipment can also introduce the bacteria into the final product.
Notable Outbreaks Linked to Ice Cream
Several large outbreaks have been tied to ice cream. In 2015, Blue Bell Creameries recalled products after listeria and salmonella concerns, and earlier outbreaks have been linked to homemade ice cream using raw eggs. The CDC tracks these events to identify contamination sources and issue warnings.
Prevention and Safe Handling
Manufacturers reduce risk by pasteurizing dairy and eggs, testing ingredients, and maintaining strict sanitation. Consumers should buy from reputable brands, store ice cream at safe temperatures, and avoid homemade recipes with raw eggs unless the eggs are pasteurized.
