Marler Clark, the food safety law firm, weighs in on E. coli lawsuit against McDonald's

Seattle, WA — Today, the E. coli attorneys at Marler Clark filed a lawsuit against McDonald’s Corporation on behalf of Sarah Johnson, in the District Court of the District of Nebraska (Complaint # 4:24-cv-03195, see attached below). McDonald’s has confirmed that Taylor Farms was the supplier of onions that have been linked to a deadly E. coli outbreak traced to Quarter Pounder burgers sold at the chain’s restaurants in at least 10 states.

As of October 24, 2024, 75 people infected with the outbreak strain of E. coli O157:H7 have been reported from 13 states, including Washington, Oregon, Montana, Wyoming, Utah, Colorado, Nebraska, Kansas, New Mexico, Iowa, Missouri, Wisconsin, Michigan. According to available information, 22 people have been hospitalized, and two developed hemolytic uremic syndrome (HUS), a serious condition that can cause kidney failure. One death has been reported from an older adult in Colorado.

Taylor Farms, the supplier of slivered onions to the McDonald’s locations, has initiated a voluntary recall and has asked customers to stop using some onions while this investigation is ongoing. Food service customers were contacted directly and told to remove onions.

In addition, on October 23, 2024, U.S. Foods reported that Taylor Farms had recalled whole, peeled onions as well as diced onions. But the wholesaler also said that it was not a McDonald’s supplier and that its recall did not include any products sold at the fast-food chain’s restaurants.

Other fast-food chains have pulled fresh onions from their menus, including Taco Bell, Pizza Hut, KFC, and Burger King. Illegal Pete’s also took onions off the menu according to a U.S. Foods recall notice. U.S. Foods, the country’s largest supplier of food-to-food service operations including restaurants in all 50 states, said the recalled onions came from a Taylor Farms facility in Colorado.

Recent onion outbreaks:

80 illnesses in 23 states linked to Gills Onions

1040 illness in 41 states linked to ProSource and Keeler Family Farms Onions

1127 illness in 48 states linked to Thomson Onions

19 illnesses in seven states linked to Taylor Farms Onion and Celery Mix
