United States – The connection between McDonald’s Quarter Pounders and an increased strain of E. coli are at 49 folks across 10 states; one person died and others found themselves in the hospital. Currently, the CDC and FDA are chasing after the source of the contamination with one of those being slivered onions, as reported by HealthDay.
Spread of the Outbreak
The CDC reports that most cases have occurred in two states, with one child in critical condition suffering from hemolytic uremic syndrome, a severe complication. Ten people have been hospitalized, as health officials race to contain the spread.
McDonald’s Pulls Ingredients Amid Investigation
According to a CDC food safety alert, many sick individuals reported eating Quarter Pounders from McDonald’s. The fast-food chain has pulled specific ingredients used in these burgers in several states while investigators work to identify the contaminated food. Slivered onions, supplied by a single distributor, are suspected.

Affected States and Menu Changes
McDonalds has however temporarily pulled onions and Quarter Pounder patties from 13 American states including Colorado, Kansas and Utah among others. Other products on the menu, including Cheeseburgers, and Big Macs, will not be affected. The company is continuing to discuss with suppliers about procuring the Quarter Pounder ingredients over the next few weeks though this may depend on regions.
FDA and CDC Measures in Source Identification
The FDA is trying to determine whether onions are the root to the outbreak and if the company that issued the recall sold the onions to other businesses. The CDC said the outbreak could expand to other states as the investigations unfold.
Signs of E.coli and the Health Hazards
E.coli infections commonly results to symptoms such as severe abdominal pain and pain while defecating, diarrhea, high fever and vomiting that manifest 3-4 days after being exposed to the source of the bacterium. The majority of people make a full recovery within a week; however, some, particularly children, are likely to develop renal issues severe enough to necessitate hospitalization, as reported by HealthDay.
Public Health Advisory
The CDC advises anyone with such symptoms after taking McDonald’s Quarter Pounder to visit a doctor and report the intake of the food product. The investigation is still ongoing, but health officials are closely observing the events.
