Health experts generally advise against eating any dough or batter raw, but that is usually because they contain eggs, which sometimes carry the bacteria salmonella.

A different germ — E. coli — triggered the voluntary recall Friday by Nestle USA of its Toll House refrigerated cookie dough products after the U.S. Food and Drug Administration reported related illnesses in dozens of people who ate the dough. The federal Centers for Disease Control is investigating the national outbreak.

Salmonella can contaminate meat, eggs, milk, seafood, vegetables and fruit. It is often spread in food contaminated during processing or by unsafe handling by consumers. People also can get the germ by touching an infected animal or its food.

E. coli can be spread through uncooked or undercooked meat and eggs, unpasteurized milk and juice, and water contaminated with human or animal waste. Both bacteria cause stomach illness. The O157:H7 strain of E. coli can cause serious illness and even lead to kidney failure and death.
