CDC warns of Salmonella outbreak linked to raw flour and cookie dough consumption.

The CDC is investigating an 11-state salmonella outbreak that has sickened at least 12 people and hospitalized three. The agency is warning against eating raw dough or batter, as flour is often raw and can contain germs that cause food poisoning. The CDC is trying to determine the specific brand of flour responsible for the illnesses and recommends using heat-treated flour, washing surfaces and utensils that touched raw flour, and keeping raw flour separate from foods that won't be cooked to prevent infection. Salmonella infections can cause diarrhea, fever, and stomach cramps, and can be more severe for young children, the elderly, and those with weakened immune systems.
