Minimizing Your Risk
Wash your hands
- Wash hands after using the bathroom and changing diapers, and before handling or eating any food.
 - Make sure that persons with diarrhea, especially children, wash their hands carefully and frequently with soap to reduce the risk of spreading the infection.
- This is particularly in daycare/preschool situations, where many outbreaks have occurred due to person-to-person spread.
 
 - Always wash hands after contact with farm animals, animal feces, and animal environments.
- Young calves are especially important carriers of E. coli.
 
 
Cook and serve your food at the appropriate temperatures
- Thoroughly cook raw meat to destroy the bacteria.
- Ground beef and hamburgers should be cooked until they are no longer pink in the middle.
 
 - If you are served an undercooked hamburger or other ground beef product in a restaurant, send it back for further cooking.
 - Storage and Cooking Temperatures
Learn more about storage and cooking temperatures - Defrost food in the refrigerator, in cold water, or in the microwave. Food should be stored in a refrigerator that is 40°F or cooler or a freezer that is 0°F or cooler.
 
Keep your food preparation areas clean
- Never place cooked hamburgers or ground beef on the unwashed plate that held raw patties.
 - Wash raw fruits and vegetables before eating.
 - Keep raw meat separate from produce and other foods when shopping for and storing groceries.
 - Wash hands, cutting boards, countertops, cutlery, and utensils after touching raw meat.
 
Avoid unpasteurized beverages
- Drink only pasteurized milk, juice, or cider.
 - Avoid foods made from unpasteurized milk.
 
Serve irradiated hamburger
- Food Irradiation
Irradiation is one of an emerging family of "end point" pasteurization technologies, which can be used to eliminate potential disease-causing microbes from our food before it goes to the consumer. 
Be careful when dealing with animals
- Always wash hands after contact with farm animals, animal feces, and animal environments.
- Young calves are especially important carriers of E. coli
