Washington: An E. coli outbreak linked to McDonald’s Quarter Pounders has affected 75 individuals across 13 states, resulting in one death in Colorado. The Centers for Disease Control and Prevention (CDC) reported that the infections are connected to slivered onions, and the Food and Drug Administration (FDA) is investigating the source of the contamination.
E. coli is a group of bacteria found in the intestines of both humans and animals. While many strains are harmless, some can lead to severe illness. Symptoms of E. coli poisoning include abdominal pain, bloody diarrhea, vomiting, and dehydration, which typically appear within 3 to 9 days after consuming contaminated food. The CDC warns that certain groups, such as young children, the elderly, pregnant women, and individuals with weakened immune systems, are at higher risk. If left untreated, severe cases can result in kidney failure and other serious complications.
In terms of the investigation, federal regulators are trying to identify whether the slivered onions or the beef patties in the Quarter Pounder burgers were responsible for the outbreak. The CDC noted that among 61 of the infected individuals, 22 required hospitalization, and two developed serious conditions related to kidney failure. Cases started appearing in late September and persisted until October 10.
Out of 42 people interviewed, all reported eating at McDonald’s, and 39 had consumed a beef hamburger. Notably, of the 36 individuals who remembered the specific burger, 31 identified it as a Quarter Pounder.
In response to the outbreak, McDonald’s has removed Quarter Pounders and slivered onions from menus in several states. Taylor Farms, the supplier of the onions for affected locations, has recalled yellow onions from its Colorado facility, which were sent to select foodservice customers.
E. coli outbreaks can occur in the United States, with the bacteria often contaminating various food products, including frozen foods and fresh vegetables.
