Health officials announced in an Oct. 30 update that the E. coli outbreak linked to onions used in McDonald’s Quarter Pounders has sickened and hospitalized more people, though the new infections are believed to predate recent actions taken by the restaurant chain to remove the onions from food service locations.

The Centers for Disease Control and Prevention (CDC) said in an Oct. 30 update that 15 new cases and five new hospitalizations have been reported since the agency first announced the E. coli outbreak and identified McDonald’s as the likely source.

“More illnesses have been reported but they are from before McDonald’s and Taylor Farms took action to remove onions from food service locations. Due to the product actions taken by both companies, CDC believes the risk to the public is very low,” the agency said in a statement.

The CDC’s latest update brings the total number of known E. coli cases linked to McDonald’s Quarter Pounders to 90, with 27 hospitalizations and one death.

Most of the E. coli cases have been reported in Colorado and Montana, which have 29 and 17 cases, respectively, followed by Nebraska with 12 cases, per the CDC. Infections have also been reported in Iowa, Kansas, Michigan, Missouri, New Mexico, Oregon, Utah, Washington, Wisconsin, and Wyoming, for a total of 13 states.

“This outbreak may not be limited to the states with known illnesses, and the true number of sick people is likely much higher than the number reported,” the CDC said in a statement, in which the agency noted that many people recover from E. coli infections without medical treatment and don’t get tested so many cases go unreported.

Symptoms of E. coli infections typically include severe stomach cramps, diarrhea (often bloody), and vomiting, usually beginning 3–4 days after exposure. Most people recover within a week, but severe cases can result in hemolytic uremic syndrome, a potentially life-threatening condition that can cause kidney failure.

The CDC advised people who consumed a McDonald’s Quarter Pounder and are experiencing symptoms such as bloody diarrhea, fever over 102 degrees F, or dehydration to seek immediate medical attention.

The Food and Drug Administration (FDA), which is carrying out an investigation into the outbreak, said in an Oct. 30 update that two people among the 90 confirmed cases of E. coli developed hemolytic uremic syndrome. The individual who died was an older adult in Colorado and was not one of the two who developed the syndrome.

The U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS) carried out an investigation into the source of the outbreak, which did not point to beef patties as the source, with fresh, slivered onions the likely culprit, per the FDA.

Taylor Farms, the supplier of the slivered onions for the affected McDonald’s locations, launched a voluntary recall of the product, which was also sold to other food service customers.

The FDA said it is working with Taylor Farms and their direct customers to determine if additional downstream customer recalls are necessary, adding that it is unlikely that the recalled onions were sold to grocery stores or directly to consumers.

“The current risk of illness from E. coli contamination is low because onions have been recalled and should no longer be available,” the FDA said, echoing the CDC’s position that the risk to public health from the outbreak is low.

The FDA added that, in addition to investigating a Taylor Farms processing center in Colorado, it has also launched an investigation into an “onion grower of interest” in Washington state in its search for the source of the outbreak.

McDonald’s has stopped using onions from Taylor Farms in its products, and the company’s CEO has apologized.

“We are certainly very sorry if someone got sick at our restaurant for eating an onion that we used on our QPC,” or quarter-pounder with cheese sandwich, CEO Chris Kempczinski said on an Oct. 29 earnings call.

“On behalf of the entire system, we are sorry for what our customers have experienced. We offer our sincere and deepest sympathies, and we are committed to making this right.”
