(Reuters) -The U.S. Food and Drug Administration was investigating whether Taylor Farms, a supplier for McDonald's (NYSE:MCD), was the possible source of the E. coli outbreak linked to Quarter Pounder hamburgers, which has killed at least one person and sickened nearly 50 others, CNBC reported on Thursday.
The FDA, however, said that they were still looking at all possible sources, adding that the investigation was ongoing.
