McDonald’s has temporarily removed its Quarter Pounder from over 2,800 locations after an E. coli outbreak linked to the burger left one person dead and nearly 50 others ill. Joe Erlinger, McDonald’s USA head, assured the public of efforts to restore trust. The CDC is investigating potential contamination in slivered onions and beef patties. Analysts warn the outbreak could affect McDonald’s Q4 sales, drawing comparisons to past food safety crises at Chipotle and Jack in the Box.
The CDC expects more cases to emerge as investigations continue.
What is E. coli? Understanding the Risk
E. coli is a bacteria commonly found in the intestines of humans and animals. While most strains are harmless, certain types, like E. coli O157, can produce toxins that cause severe foodborne illness. Symptoms usually appear within 1-10 days of exposure and can include diarrhea, fever, and in extreme cases, hemolytic uremic syndrome (HUS), which can damage the kidneys.
McDonald’s Response to Outbreak
After an E. coli outbreak linked to its Quarter Pounders, McDonald’s has pulled the item from over 2,800 restaurants. The CDC’s investigation is focusing on slivered onions and beef patties. Major supplier Taylor Farms has recalled yellow onions, and the fast-food chain has halted usage in affected areas.
