What You Should Do

Always follow these four food safety steps to prevent getting sick from E. coli:

  • Clean: Wash your hands, utensils, and surfaces often. Wash fruits and vegetables before eating, cutting, or peeling.
  • Separate: Keep food that won’t be cooked separate from raw meat, poultry, and seafood.
  • Cook: Use a food thermometer to make sure you have cooked your food to a temperature high enough to kill germsexternal icon.
  • Chill: Refrigerate foods that go bad within 2 hours (within 1 hour if it is hotter than 90°F). Thaw food in the refrigerator, not on the counter.
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 3 to 4 days after swallowing the bacteria.
    • Most people recover without treatment after 5 to 7 days.
  • Some people may develop a type of kidney failure (hemolytic uremic syndrome, also called HUS) and would need to be hospitalized.
