E. coli outbreak tied to McDonald's expands to 75 illnesses across 13 states

A widespread E. coli outbreak associated with raw onions on McDonald's Quarter Pounder hamburgers has increased the number of reported cases to 75 across 13 states, according to the Centers for Disease Control and Prevention.

Hospitalizations have quickly climbed, with at least 10 admitted. The cases involve individuals aged 13 to 88.

As a precaution, McDonald's has removed Quarter Pounders from menus in 10 states and stopped using fresh onions on other burgers. Taylor Farms, the suspected onion supplier, has recalled yellow onion products distributed to approximately 900 restaurants in Colorado, Kansas, Wyoming and other states.

These onions, identified as the contamination source, were also served at airport McDonald's locations, which may explain cases in other states.

The Food and Drug Administration is conducting an ongoing investigation and is considering all potential contributors to the outbreak.

Following regulatory advisories and supplier guidance, other fast-food chains, including Taco Bell, KFC and Pizza Hut have stopped using fresh onions in select locations.

McDonald’s stated, "Nothing is more important to us than the quality and safety of our food." While indefinitely ceasing sourcing onions from Taylor Farms.

As investigations continue, federal health officials and restaurant chains remain persistent in addressing the spread of this foodborne illness.
