Taco Bell ordered scallions removed from its 5,800 U.S. restaurants Wednesday after tests suggested they may be responsible for the E. coli outbreak that has sickened at least three dozen people in three states.
The fast-food chain said preliminary testing by an independent lab found three samples of green onions appeared to have a dangerous strain of the bacterium.
"In an abundance of caution, we've decided to pull all green onions from our restaurants until we know conclusively whether they are the cause of the E. coli outbreak," said Greg Creed, president of Irvine, Calif.-based Taco Bell.
The company would not immediately identify the supplier of the scallions, so it was unclear whether contaminated green onions reached other restaurants or supermarkets.
