Key McDonald’s Quarter Pounder ingredient recalled as likely cause of E. coli outbreak revealed

A McDonald’s supplier has recalled onions due to suspected E.coli contamination during an outbreak that has sickened 49 people and killed one.

California-based Taylor Farms launched the recall, revealed by a food supplier, after reports suggested the cut vegetables were a “likely source of contamination.”

The onions are thought to have been used in Quarter Pounders, which are at the center of the outbreak affecting ten states.

Restaurants that have the recalled onions are advised to ‘destroy’ them immediately.
