The CDC and FDA have officially ended the e.coli outbreak warning that began in October, after dozens of e.coli cases broke out across multiple states. The outbreak was linked to the slivered yellow onions sold by the Taylor Farms Colorado Spring's facility.

Both the CDC and FDA have said that the E. coli outbreak tied to slivered onions on Quarter Pounders no longer poses a risk to the public.

The U.S. Food and Drug Administration and the Centers for Disease Control and Prevention are investigating a multistate outbreak of salmonella typhimurium infections linked to cucumbers, the agencies said on Monday.
