CDC Reports 49 Illnesses Across Multiple States; Slivered Onions Under Investigation
A lethal E. coli outbreak connected to McDonald’s Quarter Pounder hamburgers has resulted in one death and sickened 49 others, according to the Centers for Disease Control and Prevention (CDC). The outbreak, predominantly affecting Colorado and Nebraska residents, has prompted swift action from the fast-food giant.
The CDC and Food and Drug Administration (FDA) have identified slivered onions as the “likely source” of contamination, leading McDonald’s to halt Quarter Pounder sales across 12 states, including Colorado, Nebraska, Kansas, and Utah. While investigators primarily suspect the onions, they haven’t ruled out the possibility of contaminated hamburger patties.
Outbreak timeline and impact
The CDC characterizes this as a “fast-moving outbreak,” with infections concentrated among customers who consumed the burgers between late September and mid-October. Ten victims required hospitalization, including a child with complications. Health officials warn that the actual infection count may exceed current figures, as many cases go unreported.
Understanding E. Coli risk
E. coli O157, the strain identified in this outbreak, is particularly concerning among foodborne pathogens. While most E. coli bacteria are harmless gut inhabitants, certain strains can cause severe illness. Symptoms typically emerge three to four days post-exposure, though this window can vary from one to ten days.
E. coli: Symptoms
Health experts emphasize vigilance for severe stomach cramps, bloody diarrhea, vomiting, and fever. The CDC urges immediate medical attention for symptoms persisting beyond three days, high fevers exceeding 102°F, severe vomiting, or dehydration signs. Most patients recover within a week, but some cases can develop into hemolytic uremic syndrome (HUS), a serious kidney condition requiring hospitalization.
Prevention tips
While this outbreak is specific to McDonald’s products, general E. coli prevention includes:
- Thoroughly washing hands before handling food
- Properly cooking meat products
- Avoiding cross-contamination in food preparation
- Washing fruits and vegetables before consumption
Public health response
As investigations continue, health officials are working closely with McDonald’s to prevent further infections. The restaurant chain has suspended use of the suspected onions while maintaining cooperation with health authorities to identify and eliminate the contamination source.
The CDC continues to monitor the situation and advises consumers who experience symptoms after consuming McDonald’s products to seek immediate medical attention and report their illness to local health authorities.
