You can best prevent foodborne illness by

Clean. Wash your hands often and always before you touch food. Keep your knives, cutting boards, and counters clean. You can wash them with hot, soapy water, or put items in the dishwasher and use a disinfectant on your counter. Wash fresh fruits and vegetables.

Separate. Keep germs from raw meat from getting on fruits, vegetables, and other foods. Put cooked meat on a clean platter, not back on the one that held the raw meat.

Cook. Make sure that meat, chicken, fish, and eggs are fully cooked.

Chill. Refrigerate leftovers right away. Don't leave cut fruits and vegetables at room temperature for a long time.

When in doubt, throw it out. If you aren't sure if a food is safe, don't eat it.
