Sample of Nestlé Cookie Dough Has E. Coli Bacteria

Nestlé USA said Wednesday that two samples of its Toll House refrigerated cookie dough made at a Virginia factory tested positive for E. coli bacteria this week despite rigorous safety measures put in place after a recall of the product last summer.

Nestlé also said the tainted dough had not left the factory and no recall was necessary.

The company said on Wednesday that it would shut the plant in Danville, Va., for nearly two weeks while it changes its recipe and production processes. When it reopens, the company will begin using flour that has been heated to kill dangerous bacteria, including E. coli, salmonella and listeria.

Nestlé said that all cookie dough currently in stores is safe and that it was not recalling any of the product.

It said that after last summer’s recall, it began testing samples of every batch of dough for E. coli O157:H7, the toxic strain behind last year’s outbreak.
