The Food and Drug Administration says a sample of raw cookie dough collected at a Nestle USA manufacturing plant last week has tested positive for E. coli.
The FDA says the sample of Toll House refrigerated prepackaged dough was manufactured Feb. 10.
Nestle voluntarily recalled all Toll House refrigerated cookie dough products made at the Danville, Va., factory earlier this month after the FDA told Nestle it suspected consumers may have been exposed to E. coli bacteria after eating the dough raw.
FDA spokeswoman Stephanie Kwisnek says the FDA is working with Glendale, Calif.-based unit of Switzerland-based Nestle SA to find the source of the contamination.
