Oct. 31, 2024
Most people infected with Shiga toxin-producing E. coli experience severe stomach cramps, diarrhea (often bloody), and vomiting.

An update to CDC's Food Safety Alert regarding an outbreak of E. coli infections linked to onions served at McDonald's has been posted: https://www.cdc.gov/ecoli/outbreaks/e-coli-O157.html.

Key points:

  • Epidemiologic and traceback information show that fresh, slivered onions are the likely source of illness in this outbreak. As of October 30, 2024:
    • 15 new illnesses have been reported, bringing the total to 90.
    • Five more people have been hospitalized, bringing the total to 27.
    • The most recent illness on-set date is October 16, 2024.
  • All new illnesses occurred before McDonald's and Taylor Farms took action to remove onions from food service locations.

What you should do:

  • Businesses should not use recalled onions supplied by Taylor Farms.
