McDonald's Confirms No E. coli in Beef Patties; Quarter Pounders to Return

McDonald's has confirmed that its beef patties tested negative for E. coli after food poisoning reports linked to the chain's Quarter Pounders in the U.S. The fast-food giant will reinstate the popular burger on its menu after testing by the Colorado Agriculture Department found no traces of the bacteria.

Recently it was reported that approximately fifty people fell ill after eating quarter pounders. A company spokesman said the probable source of contamination was slivered onions from a particular supplier McDonald's will stop using.

According to McDonald's Chief Supply Chain Officer, Cesar Pina, the contamination from that outbreak should already have been eradicated. The company stopped selling the Quarter Pounder in those areas, as was the case with those places located in the Midwest and Mountain regions, due to the outbreak.

The infected onions have been distributed to about 900 locations. Some are in busy transportation hubs like airports. The company has received clearance from health officials, and fresh Quarter Pounders will begin to flood the restaurants starting this coming week.
