McDonald’s experienced a significant decline in its shares after the Centers for Disease Control and Prevention (CDC) reported an E. coli outbreak linked to its Quarter Pounder burgers. The outbreak has resulted in 10 hospitalizations and one death, affecting 49 people across 10 states, primarily in Colorado and Nebraska.
Investigation and Immediate Actions
Initial investigations suggest the outbreak may be connected to slivered onions used in the Quarter Pounder, sourced from a single supplier. In response, McDonald’s has halted the use of these onions in certain regions and temporarily removed Quarter Pounders from menus in several Western states, including Colorado, Kansas, Utah, and Wyoming.
Impact on Menu and Safety Measures
McDonald’s President Joe Erlinger assured customers that other menu items, such as cheeseburgers and Big Macs, remain unaffected, as they use a different type of onion product. The company is working swiftly to resolve the issue and restore the full menu in the affected areas.
Ongoing Concerns
The CDC warns that the actual number of affected individuals could be higher, as many recover without seeking medical attention or testing. Symptoms of E. coli infection include stomach cramps, diarrhea, and vomiting, typically starting three to four days after exposure.
Previous Incidents
This is not the first E. coli outbreak linked to McDonald’s. In 2022, several children in Alabama fell ill after consuming Chicken McNuggets.
