What You Need to Know

  • Don’t taste or eat raw (unbaked) dough or batter.
  • Don’t let children handle or play with raw dough, including play clay and dough for crafts.
  • Uncooked flour and raw eggs can contain germs that can make you sick if you taste raw dough.
  • Wash your hands, bowls, utensils, and countertops after handling raw flour, eggs, or dough.

Spending time with family while baking is a great way to celebrate special occasions. When making cookies, brownies, cakes, or bread, you might be tempted to taste a bite before it’s fully baked.

But you can get sick after eating or tasting raw (unbaked) dough or batter. Children can get sick from handling or eating raw dough used for crafts or play clay, too. Follow these safety tips to help you and your loved ones stay healthy when preparing and handling raw dough.

Raw Dough Can Contain Germs That Make You Sick

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). 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 food made with flour is baked or cooked.

CDC investigated outbreaks of E. coli infections linked to raw flour or cake mix in 20162019, and 2021. 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 FDA’s recall listexternal icon). If you have any recalled flour or baking mixes, throw them away.

Raw eggs are another ingredient in dough and batter that can make you or your loved ones sick. Raw or lightly cooked eggs can contain Salmonella, a germ that causes food poisoning. Find out how to handle and cook eggs properly.

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. Read the label carefully to make sure the dough is meant to be eaten without baking or cooking.

Stay Safe When Handling Flour and Other Raw Ingredients

Follow these practices to prevent food poisoning when you are baking and cooking with flour and other raw ingredients.

  • Do not taste or eat any raw dough or batter. This includes dough or batter for cookies, brownies, cakes, pie crusts, tortillas, pizza, biscuits, pancakes, or crafts made with raw flour, such as homemade play dough or holiday ornaments.
  • Do not let children play with or eat raw dough, including dough for crafts.
  • Bake raw dough, such as cookie dough, and batter, such as cake mix, before eating.
  • Follow the recipe or package directions for cooking or baking. Use the temperature and cooking time given in the recipe or directions.
  • Do not make milkshakes with products that contain raw flour, such as cake mix.
  • Do not use raw homemade cookie dough in ice cream.
    • Cookie dough ice cream sold in stores contains dough that has been treated to kill harmful germs.
  • Keep raw foods, such as flour and eggs, separate from ready-to-eat foods. Because flour is a powder, it can spread easily.
  • Follow label directions to refrigerate products containing raw dough or eggs until they are baked or cooked (for example, store-bought cookie dough).
  • Clean up thoroughly after handling flour, eggs, or raw dough.
    • Wash your hands with soap and water after handling flour, raw eggs, or any surfaces they have touched.
    • Wash bowls, utensils, countertops, and other surfaces with warm, soapy water.
