Food-borne illnesses (sometimes called food poisoning) are caused by eating foods contaminated with pathogens (disease-causing agents) such as viruses, parasites, bacteria, or fungi. Raw, unwashed, or undercooked foods are at greatest risk of being contaminated. However, most food-borne illnesses can be prevented if food is handled properly. Typical symptoms of food-borne illnesses include nausea, vomiting, diarrhea, abdominal cramps, and sometimes fever. Infants, the elderly, and people with diabetes, cancer, or AIDS are at an increased risk because their immune systems may not be functioning properly.

A severe complication of some types of food-borne illness is hemolytic uremic syndrome, a combination of anemia (low red blood cell count), profuse bleeding, and kidney failure.

PREVENTING FOOD-BORNE ILLNESSES


  • Wash your hands thoroughly with soap and water before and after handling food

  • Wash raw vegetables and fruits with running water before eating

  • Always clean surfaces like cutting boards that touch raw foods between each use

  • Cook meat, poultry, and eggs thoroughly to an internal temperature of 160° F
  • Refrigerate (40° F or below) or freeze (0° F or below) leftovers promptly
  • Don't eat perishable foods (meat, poultry, fish, eggs, dairy foods) if they have been out of refrigeration for more than 2 hours





  • It is often difficult to distinguish a food-borne illness from other common causes of vomiting and diarrhea such as viral gastroenteritis (viral infection of the intestinal tract usually lasting a day or two). If several individuals get sick within a few hours of eating the same food, a food-borne illness should be considered. If you think you or a family member may have a food-borne illness, consult your doctor. If you think food contamination occurred at a restaurant or other food service facility, call your local health department to investigate.
