Investigation Launched into E. Coli Outbreak Linked to McDonald's Burgers
US health authorities are investigating an outbreak of E. coli infections that has affected 50 individuals, leading to one death and ten hospitalizations. The outbreak is primarily linked to McDonald's Quarter Pounder burgers, with most cases reported in Colorado and Nebraska. According to the US Centers for Disease Control and Prevention (CDC), the first reported illness occurred on September 27, with the peak of cases on October 7. The last case was recorded on October 11.
The CDC has confirmed that the type of bacteria involved in this outbreak is E. coli O157:H7, known for causing severe gastrointestinal illness. Symptoms typically begin three to four days after exposure and can include severe stomach cramps, diarrhea (often bloody), and vomiting. While most individuals recover within five to seven days, some, particularly young children, may develop serious complications such as hemolytic uremic syndrome (HUS).
In response to the outbreak, McDonald's has halted the use of fresh sliced onions and Quarter Pounder burgers in several states while the investigation continues. The company is collaborating with health authorities to identify the specific ingredient responsible for the contamination. The CDC has reported that the highest number of cases are in Colorado, with 27 infections, followed by Nebraska with nine, and Utah and Wyoming with four each. Other states affected include Wisconsin, Iowa, Montana, Oregon, Missouri, and Kansas.
