McDonald’s E. coli outbreak linked to onions by CDC

The Centers for Disease Control and Prevention (CDC) has issued a update confirms that sliced ​​onions are served on McDonald’s Quarter Pounder hamburgers “is the likely source” of the latest E. coli outbreak.

With 90 reported cases, including 15 newly identified, the CDC assures the public that it believes the current risk is “very low“, follows quick actions taken by McDonald’s and its supplier, Taylor Farms.

The outbreak has resulted in 27 hospitalizations and one death. While more cases have surfaced, they occurred before when the onions were removed from food service locations, according to the CDC. Most affected persons reported consuming McDonald’s Quarter Pounders, which have the distinctive minced onions, before becoming ill.

In response, McDonald’s pulled the onions and beef patties from their menus as it sought to identify the source of the contamination. The fast food giant has stated that it will offer its Quarter Pounders again – minus the onions.

In addition, Burger King (QSR+0.63%), along with Yum! Brand owned Pizza Hut (YUM+0.97%), Taco Bell and KFC, have removed chopped onions indefinitely.

The likely culprit is Taylor Farms yellow onions, which have been since recalled. Food service operators have been instructed to stop selling the recalled onions and “destroy” any remaining stock. It is important to note that these onions were distributed exclusively to restaurants, so they are not expected to have reached grocery stores.

While the investigation continues, the CDC encourages anyone experiencing symptoms of E. Coli, such as bloody diarrhea, vomiting or dehydration, to contact their doctor.
