ATLANTA — According to federal health authorities, an outbreak of E. coli food poisoning has been associated with McDonald’s Quarter Pounders, resulting in illness for at least 49 individuals.

The Centers for Disease Control and Prevention (CDC) is actively investigating the situation to determine the source of this contamination. The outbreak has raised concerns among consumers who frequently dine at the fast-food chain, as many of those affected report symptoms consistent with E. coli infection.

Health officials are urging anyone who has experienced severe gastrointestinal distress after consuming a Quarter Pounder at McDonald’s to seek medical attention and report their illness. E. coli infections can lead to serious health complications, particularly in vulnerable populations such as young children and the elderly.

As the investigation unfolds, McDonald’s is cooperating with health officials to trace the source of the contaminated beef patties. The CDC is also working to identify additional cases and has advised restaurants to monitor their beef products closely.

Customers are advised to be vigilant about food safety practices and to remain informed about food recalls and safety alerts as the situation develops. Federal officials continue to stress the importance of thoroughly cooking meat to safe temperatures to mitigate the risk of such foodborne illnesses.
