The number of E. coli cases from onions served at McDonald’s rose from 15 to 90, according to the CDC.

Epidemiologic and traceback information show that the onions served at McDonald’s are likely the source of recent E. coli outbreaks.

The CDC shares that five more people have been hospitalized, now bringing the total to 27.

During this time, McDonald’s and Taylor Farms removed onions from their food service locations. The CDC believes that the removal of onions has lowered the risk to the public.

If you have E. coli, the CDC recommends that you:

  • Seek healthcare
  • Tell your healthcare provider about what you ate

The CDC shares that most people that experience E. coli see symptoms such as:

  • Severe stomach cramps, diarrhea (often bloody) and vomiting
  • Symptoms usually start 3 or 4 days after swallowing the bacteria
  • Most people recover without treatment after 5 to 7 days
  • Some people can develop serious kidney problems like hemolytic uremic syndrome
