A recent food safety alert has been issued by the US Centers for Disease Control and Prevention (CDC) concerning McDonald's Quarter Pounder sandwiches. These sandwiches have been linked to an E. coli outbreak that has affected at least 49 people across 10 states, with one death reported. The source of the contamination is still under investigation, but the US Food and Drug Administration (FDA) has pointed to the slivered onions or beef patties used in the Quarter Pounder sandwiches as the likely culprits. In response, McDonald's has temporarily removed Quarter Pounders from the menu in about 20% of its stores and has stopped using the specific onions and beef patties in several states. The beef patties are used only for the Quarter Pounders, and the slivered onions are primarily used for this sandwich.

E. coli infections can be quite serious, causing symptoms such as severe stomach cramps, diarrhea, fever, and vomiting. While most people recover within a week, some may develop kidney problems and need hospitalization. Those at highest risk include seniors, young children, and people with weakened immune systems. The CDC has reported that 10 hospitalizations have been linked to this outbreak, including a child who developed a serious kidney complication.

The CDC is actively investigating the outbreak and expects the number of cases to grow as they identify more genetic connections between the outbreak strain and the bacteria causing human infections. Most of the illnesses have been reported in Colorado and Nebraska, but cases have also been found in other states.

If you've recently eaten a McDonald's Quarter Pounder and are experiencing severe E. coli symptoms like high fever, bloody diarrhea, or prolonged vomiting, it's recommended that you contact your doctor. Foodborne illnesses in the US have been on the rise, with some infections like E. coli and Campylobacter bacteria exceeding federal targets for reduction.
