At least 75 people fall ill as McDonald’s deadly E. coli outbreak spreads

The new cases reported Friday represented a sharp increase from the original count of 49 in 10 states. The majority of illnesses were reported in Colorado, with 26 cases. At least 13 people fell ill in Montana, 11 in Nebraska, 5 in New Mexico and Utah, 4 in Missouri and Wyoming, two in Michigan and one each in Iowa, Kansas, Oregon, Wisconsin and Washington, the CDC reported.

McDonald’s said Friday that it did not remove the Quarter Pounder from any additional restaurants due to the CDC’s rising illness count. The company noted that some cases in states outside the original region were travel-related.

The CDC said some people who became ill reported traveling to other states before symptoms began. At least three people said they ate at McDonald’s during their trip. Illnesses were reported between September 27 and October 11.

Taylor Farms notified its customers directly about the onion recall, but did not inform the public, an FDA official said. Companies often issue press releases and the FDA sends public notifications about recalls, but they are not required.

While it is unclear whether the recalled onions were the source of the outbreak, several other fast food restaurants, including Taco Bell, Pizza Hut, KFC and Burger King, removed onions from some menus in certain areas this week.

Restaurant Brands International, owner of Burger King, said 5% of its restaurants use whole onions distributed by Taylor Farms facilities in Colorado. Employees wash, peel and cut them.

Although it was not contacted by health officials and had no signs of illness, Restaurant Brands said it asked restaurants that received onions from the Colorado facility to dispose of them.

The outbreak involves infections. with E. coli 0157:H7, a type of bacteria which produces a dangerous toxin. It causes about 74,000 infections in the U.S. annually, leading to more than 2,000 hospitalizations and 61 deaths each year, according to the CDC.

People sickened by the outbreak have already sued McDonald’s, according to court records. According to her lawsuit, Clarissa DeBock ate food from a local McDonald’s in Nebraska on September 18, became ill on September 23, and sought emergency care two days later before she was diagnosed with an E. coli infection.

Symptoms of E. coli poisoning can occur quickly, one to two days after eating contaminated food. They usually include fever, vomiting, diarrhea or bloody diarrhea, and signs of dehydration: little or no urination, increased thirst, and dizziness. The infection is especially dangerous for children under 5 years old, elderly people, pregnant people, or people who have weakened immune systems.
