The Centers for Disease Control and Prevention (CDC) has released a new update about the link between E. coli breakout and McDonald's Quarter Pounder hamburgers. The number of infected individuals has risen to 75 from the previous 49 (update on October 22). 22 individuals have been hospitalized, and the contaminated samples have been found in 13 states.

Following the latest news, Yum! Brands, the owner of fast-food chains like KFC, Taco Bell, and Pizza Hut, has removed fresh onions from its meals at select US stores.

CDC's preliminary investigations have linked the E. coli breakout to contaminated onions. According to the CDC, Taylor Farms has initiated a voluntary recall of the onions from its partnered food chains, like KFC, Pizza Hut, and Taco Bell.

In a statement to CBS News, a spokesperson for Yum! Brands confirmed the news, stating,

"We will continue following supplier and regulatory guidance to ensure the ongoing safety and quality of our food."

Additionally, Burger King has revealed that 5% of their chains receive onions from Taylor Farms. Although no cases have been reported at those locations, Burger King has noted that they have disposed of the stock and will restock.

Due to the prompt actions taken by both the companies, Mcdonald's and Taylor Farms, the CDC has noted that the public risk of the infection is low. The last reported case was on October 10.

While the impact of this outbreak on McDonald's is unclear, their shares were reportedly 7% down on Wednesday. According to BBC News, the first lawsuit has been filed by a man who fell ill two days after eating in Greeley, Colorado. It is unclear if other lawsuits have been filed against the burger giant, but this has put it at a further defense.


As a precautionary step, fast food chains, including KFC, Burger King, and Pizza Hut, have temporarily stopped using yellow onions as a topping. This decision comes in light of the investigation by health officials into the E. coli outbreak linked to McDonald's. It is recommended that one immediately visit their doctor if symptoms of E. coli infection like excessive diarrhea, fever, vomiting, and cramps persist after a few days.
