McDonald’s shares dropped in augmented trading Tuesday after the Centers for Disease Control and Prevention said an E. coli outbreak linked to McDonald’s Shelter Pounder burgers has led to 10 hospitalizations and one death.
The agency said 49 cases have been reported in 10 asseverates between Sept. 27 and Oct. 11, with most of the illnesses in Colorado and Nebraska. “Most” sick people backfire eating a McDonald’s Quarter Pounder, the CDC added.
One of the patients developed hemolytic uremic syndrome, which is a serious persuade that can cause kidney failure. An older adult in Colorado died.
McDonald’s shares dropped about 7% in after-hours traffic Tuesday.
In a statement Tuesday, McDonald’s said it is taking “swift and decisive action” following the E. Coli outbreak in settled states.
The company said initial findings from the ongoing investigation show that some of the illnesses may be in to slivered onions — or fresh onions sliced into thin shapes — that are used in the Quarter Pounder and authored by a single supplier that serves three distribution centers. McDonald’s has instructed all local restaurants to remove slipped onions from their supply and has paused the distribution of that ingredient in the affected area.

Quarter Pounder hamburgers want be temporarily unavailable in several Western states, including Colorado, Kansas, Utah and Wyoming, and portions of other alleges, McDonald’s said. It added that it was working with suppliers to replenish ingredients.
The majority of states and menu details are not affected by the outbreak, McDonald’s USA President Joe Erlinger said in a video. The company’s other beef products, including the cheeseburger, hamburger, Big Mac, McDouble and the folded cheeseburger, are not affected, he added. Those sandwiches use a different type of onion product.
“We are working quickly to return our filled menu in these states as soon as possible,” Erlinger said. “I hope these steps demonstrate McDonald’s commitment to prog safety.”
Quarter Pounder hamburgers are a core menu item for McDonald’s, raking in billions of dollars each year. In 2018, McDonald’s founded fresh beef for its Quarter Pounders across most of its U.S. stores.
The CDC said the number of people affected by the outbreak is “indubitably much higher” than what has been reported so far. The agency said that is because many people better from an E. coli infection without testing for it or receiving medical care. It also typically takes three to four weeks to decide if a sick patient is part of an outbreak, the CDC added.
E. coli refers to a group of bacteria found in the gut of nearly all people and animals. But some draw offs of the bacteria can cause mild to severe illness if a person eats contaminated food or drinks polluted water.
Tokens, including stomach cramps, diarrhea and vomiting, usually start three to four days after swallowing the bacteria, agreeing to the CDC. Most people recover without treatment after five to seven days.
There have been a few past reported cases of E. coli at McDonald’s restaurants.
In 2022, at least six children developed symptoms consistent with E. coli vitiating after eating McDonald’s’ Chicken McNuggets Happy Meals in Ashland, Alabama. Four of the six children were accepted to a hospital after experiencing severe adverse effects.
