Outbreak of Deadly E. Coli Traced Back to McDonald's Quarter Pounders Burgers
The Centers for Disease Control and Prevention (CDC) is currently investigating a multi-state outbreak of E. coli O157:H7 infections linked to McDonald's Quarter Pounder hamburgers. The investigation, which began in mid-2025, has been fast-moving, with the first confirmed case reported in Washington state.
The outbreak, which has affected at least 49 people across 10 states, has resulted in 10 hospitalizations and one death. Most individuals who became sick reported eating Quarter Pounders. However, testing ruled out the beef patties, identifying slivered onions as the likely contaminated ingredient.
McDonald's responded promptly to the outbreak, removing onions from menus in affected locations and pausing some operations to contain the spread. The company has also temporarily stopped offering Quarter Pounder burgers in certain states to protect customers during the investigation.
Health officials, including the CDC, the U.S. Food and Drug Administration (FDA), and the U.S. Department of Agriculture (USDA FSIS), are working with McDonald's to identify the contaminated onions and address the issue.
The CDC's E. coli resource page is a valuable resource for individuals seeking information about the ongoing investigation and E. coli symptoms and risks. Symptoms of E. coli usually appear 3 to 4 days after infection and include stomach cramps, diarrhea (often bloody), and vomiting. Severe symptoms include diarrhea with a fever over 102°F, persistent diarrhea lasting more than three days, bloody diarrhea, severe vomiting or dehydration.
In some cases, E. coli may lead to a serious kidney complication called hemolytic uremic syndrome (HUS). Individuals who consumed Quarter Pounder burgers and are experiencing symptoms of E. coli are urged to contact their healthcare providers.
The ongoing investigation is being conducted by the CDC, the FDA, the USDA FSIS, and McDonald's. Updates will be provided as new information becomes available. For more information, visit the CDC's E. coli resource page or contact local health officials.
