Food maker Nestle USA has issued a voluntary recall for its Toll House refrigerated cookie dough products after a number of illnesses were reported by those who ate the dough raw.

The company said the Food and Drug Administration (FDA) and the Centers for Disease Control are investigating reported E. coli illnesses that might be related to the ingestion of raw cookie dough.

E. coli is a potentially deadly bacterium that can cause bloody diarrhea, dehydration and, in the most severe cases, kidney failure.

E.coli bacterium is commonly found in the lower intestine of warm-blooded organisms and transmission often occurs via fecal-oral transmission.

The FDA said there have been 66 reports of illness across 28 states since March. About 25 people have been hospitalized, but no one has died.

The FDA has advised consumers to throw away any prepackaged, refrigerated Nestle Toll House cookie dough products in their homes., and told retailers, restaurateurs and employees at other food-service operations not to sell or serve any of the products.

Nestle spokeswoman Roz O’Hearn said, “this has been a very quickly moving situation,” and the company took action less than 24 hours after hearing of the problem.

O’Hearn said the company will “cooperate fully” with the FDA’s investigation.

The recall includes refrigerated cookie bar dough, cookie dough tub, cookie dough tubes, limited edition cookie dough items, seasonal cookie dough and Ultimates cookie bar dough. It does not affect any other Toll House products.
