Yum Brands announced Thursday it has removed fresh onions from select locations in the wake of the E. coli outbreak.

Fast food giants KFC and Pizza Hut are removing onions used in select menu items across the U.S. following concerns of possible E. coli contamination linked to a recent outbreak associated with McDonald's restaurants.

The produce company that supplied onions to McDonald’s recently removed products from the market because of potential E. coli contamination.
