Safely handle raw flour and dough
Centers for Disease Control and Prevention (CDC)
For food safety when cooking or baking, wash your hands, bowls, utensils, and countertops before and after handling raw flour, eggs, or dough, and carefully follow the recipe or package directions. Uncooked flour and raw eggs can contain germs that can make you sick. tasting or eating raw (unbaked) dough or batter can put you at risk for food poisoning.
Risks of raw dough
Flour doesn’t look like a raw food, but most flour is raw. That means it hasn’t been treated to kill germs that cause food poisoning, such as Escherichia coli (E. coli) and Salmonella. These harmful germs can contaminate grain while it’s still in the field or flour while it’s being made. Steps like grinding grain and bleaching flour don’t kill harmful germs — and these germs can end up in flour or baking mixes you buy at the store. You can get sick if you eat unbaked dough or batter made with flour containing germs. Germs are killed only when flour is baked or cooked.
CDC investigated outbreaks linked to raw flour or cake mix in 2016, 2019, 2021, and 2023. Some of these investigations led to recalls. Flour and baking mixes containing flour have long shelf lives, meaning they do not go bad quickly. It’s a good idea to check your pantry to see if you have any flour or baking mixes that have been recalled in recent years; search the FDA’s recall list at www.fda.gov/safety/recalls-market-withdrawals-safety-alerts. Throw away any recalled flour or baking mixes you have.
Raw eggs are another ingredient in dough and batter that can make you sick if eaten. Raw and lightly cooked eggs can contain Salmonella.
Some companies make edible cookie dough and brownie batter that you can find in stores. These products are made with heat-treated flour and pasteurized eggs or no eggs. Before enjoying, read the label carefully to make sure the dough is meant to be eaten without baking or cooking.
