As we are preparing for the upcoming holiday season, keep in mind that raw flour can give you Salmonella and E. coli if consumed raw. Flour is made from processing raw grains that are grown in fields, but this process does not kill the bacteria found in the raw grains. Some tips to avoid getting sick include not eating or tasting raw dough products, keeping flour away from ready-to-eat foods, and refrigerating cookie and pastry dough according to the directions on the package.
