A severe E. coli outbreak linked to McDonald’s Quarter Pounder hamburgers has resulted in one death and left dozens of people sick across the U.S., according to the Centers for Disease Control and Prevention (CDC). The outbreak, which began in late September, has primarily affected Colorado and Nebraska but spans ten western states.
The CDC confirmed that all 49 individuals affected shared the same strain of E. coli. Among them, ten have been hospitalized, with one child diagnosed with hemolytic uremic syndrome, a serious kidney condition that can cause long-term damage. Tragically, an older adult in Colorado has died from the illness.
What We Know So Far
Health officials are focusing their investigation on the ingredients of the Quarter Pounder, particularly slivered onions and beef patties, which have been removed from McDonald’s restaurants in the affected states. Though the exact cause is still under investigation, McDonald’s has proactively taken steps to address the situation, removing these ingredients as a precaution.
Joe Erlinger, president of McDonald’s USA, emphasized the company’s commitment to food safety, stating, “We’ve taken steps to proactively remove slivered onions, which are used in Quarter Pounders, in select states… We’ve also made the decision to temporarily remove the Quarter Pounder from restaurants in select states.” Other menu items, including different beef products, remain available in affected regions, and most U.S. states are not impacted by the outbreak.
What Should You Do?
If you have eaten a Quarter Pounder from McDonald’s recently and developed symptoms such as severe diarrhea, fever over 102°F (38.9°C), or vomiting, the CDC urges you to seek medical attention immediately. Symptoms of E. coli poisoning typically appear three to four days after exposure, and while most people recover without treatment in about a week, some cases can lead to more serious health issues.
What Is E. Coli and Why Is It Dangerous?
E. coli bacteria can cause a range of illnesses, from mild stomach cramps and diarrhea to severe conditions like hemolytic uremic syndrome, which damages blood vessels in the kidneys. This condition can be life-threatening, especially for children and the elderly. The CDC advises that anyone who suspects they have been exposed to contaminated food should seek medical care if symptoms worsen or persist.
The outbreak has not only sparked concern among the public but also affected McDonald’s stock, which fell over six percent in after-hours trading following the CDC’s announcement. Authorities continue to monitor the situation closely, and more updates are expected as the investigation progresses.
Stay Informed and Take Precautions
Have you eaten at McDonald’s in the affected states? Are you experiencing symptoms? Don’t wait—contact a healthcare provider to stay safe. The CDC and local health agencies are working to contain the outbreak, but your vigilance is key to staying healthy.
