About 50 people have been reported infected in an E. coli outbreak involving McDonald’s Quarter Pounder sandwiches.
The outbreak began around Sept. 27. In addition to Nebraska and Colorado, infections have been confirmed in Oregon, Montana, Wyoming, Utah, Kansas, Missouri, Iowa and Wisconsin.
So far, around 50 people have been reported infected, with 27 infections occurring in Nebraska and nine in Colorado, according to the CDC.
Officials estimate that the actual number of people infected is probably much higher as it usually takes three to four weeks to determine if a sick person is part of an outbreak, and also because many people recover without being tested for E. coli.
IN RESPONSE, the fast food chain has proactively removed the onions and patties used for the burgers from stores in the affected states, according to the CDC. As a result, Quarter Pounder hamburgers will be temporarily unavailable in some states.
Most instances of E. coli contamination are caused by poor sanitation practices, such as employees not washing their hands, crops being grown too close to farms where animals live and contaminate the soil and runoff with feces, and companies’ failure to properly process and test foods, according to Teresa Murray, consumer watchdog director for the Public Interest Research Group.
One of the last major E. coli outbreaks took place in 2015, when contaminated food served at Chipotle Mexican Grill restaurants was linked to around 60 cases across the nation.
Symptoms of E. coli
Most people infected with Shiga toxin-producing E. coli experience severe stomach cramps, diarrhea (often bloody), and vomiting.Symptoms usually start three to four days after ingesting the bacteria.Most people recover without treatment after five to seven days.
Some people may develop serious kidney problems (hemolytic uremic syndrome, also called HUS) and would need to be hospitalized.
Call your healthcare provider if you have severe E. coli symptoms.
