The FDA has advised against consuming raw cookie dough. Eating any type of rough dough is not recommended. Furthermore, children should not play with rough dough of any kind, as germs can grow and get on their hands. If their contaminated hands go into their mouths, they can become sick.
Leslie Smoot, a senior advisor in FDA’s Office of Food Safety, said, “Flour is derived from a grain that comes directly from the field, and typically is not treated to kill bacteria.” Bacteria from animal waste can contaminate grains. Boiling, baking, roasting, microwaving, or frying raw flour kills harmful bacteria. But raw dough or batter can still harbor germs.
