Many people in Colorado and around the country became ill following an E. coli outbreak tied to McDonald’s Quarter Pounders.

Taylor Farms has recalled yellow onions supplied to restaurants, following an E. coli outbreak linked to McDonald's Quarter Pounder burgers.

A California-based produce company has been identified as the source of the fresh onions linked to the McDonald’s E. coli outbreak, and the company has issued a voluntary recall of onion products from a Colorado distribution center.
