Most grains are not treated to kill bacteria.
Do you find raw cookie dough irresistible? It could be a problem. The flour may contain bacteria--specifically Shiga toxin-producing E. coli O121. Common, light symptoms are diarrhea and abdominal cramps that go away in a week. However, in children under 5, it can cause a type of kidney failure. Be aware that even homemade "play" clay from raw dough could cause an infection. Read the whole U.S. FDA statement.
PositiveTip: For your safety, avoid eating raw dough and wash hands, surfaces and utensils thoroughly after contact with flour.
Beware of raw cookie dough, it could make you sick.
Looking forward to some raw cookie dough this holiday? Think again! When scientists examined 35 cases of E. coli food poisoning occuring in mid-2009, all but two of the hospitalized victims had eaten uncooked chocolate-chip cookie dough. Two-thirds of the patients were younger than 19 years old. While you might blame the eggs used, they had been pasturized. Only the flour had not been safeguarded from E. coli.
PositiveTip: Safely enjoy cookie dough--after it has been baked in the oven!
