WASHINGTON (AP) – Federal testing has failed to confirm green onions as the source of an outbreak of E. coli that sickened 64 people who ate in Taco Bell restaurants in the Northeast, health officials said Monday.

Over the weekend, Taco Bell officials said they determined that scallions were the likely source of the bacteria. But follow-up federal testing of those samples were negative for E. coli. “In that context, we have not ruled out any food items,” said Dr. David Acheson, chief medical officer for the FDA’s Center for Food Safety and Applied Nutrition.
