Think again…Escherichia coli  will confine to your intestines and cause a variety of intestinal and UTI problems.   

In a major breakthrough in the nationwide outbreak of E. coli, investigators have found a sample of Toll House cookie dough contaminated with the pathogen at Nestlé’s Danville, Va., plant.

The Food and Drug Administration today told Nestlé officials they had located a 16.5 ounce production sample of Toll House chocolate chip cookie dough at the same plant where the popular confection is made. The ‘best-by’ date is June 10, 2009.

This is a huge step in the investigation, but neither investigators nor Nestlé officials know as of yet how E. coli 0157:H7 got into the dough, or which ingredient in particular is contaminated.

“It’s very disappointing,” said Edie Burge, a spokeswoman for the company, but additional testing is still needed to confirm the genetic connection with the 69 confirmed cases of E. coli poisoning in a nationwide outbreak.

Nestlé is continuing to work closely with the FDA on the matter.
