How Food Becomes Unsafe
Contamination
When food contains:
- Bacteria, parasites, viruses or other microorganisms that grow and produce natural poisons
- Foreign chemicals, such as cleansers
- Foreign objects, such as glass or bits of packaging, accidentally mixed into food
Cross-Contamination
When safe food comes into contact with:
- Unsafe or raw food
- Unclean utensils, glassware or dishware
- Unclean work surfaces
- Dirty hands
You can't always see or smell that food is unsafe - that's why we're so careful to avoid the conditions that can make food unsafe.
When to See a Doctor
You should see a healthcare provider if you have the following symptoms:
- High fever (temperature over 101.5 F, measured orally)
- Blood in the stools
- Prolonged vomiting that prevents keeping liquids down (which can lead to dehydration)
- Signs of dehydration, including a decrease in urination, a dry mouth and throat, and feeling dizzy when standing up.
- Diarrhea that lasts more than 3 days
Do not be surprised if your doctor does not prescribe an antibiotic. Many diarrheal illnesses are caused by viruses and will improve in 2 or 3 days without antibiotic therapy. In fact, antibiotics have no effect on viruses, and using an antibiotic to treat a viral infection could cause more harm than good.
How to Stay Healthy
- The 4 Steps to Food Safety
- Clean: Wash hands, utensils, and surfaces often while preparing and cooking food
- Separate: Don't cross contaminate; keep raw and cooked foods away from each other
- Cook: Ensure foods are cooked to the right temperature
- Chill: Refrigerate and freeze food properly and promptly
- Cold Food Storage Chart
- Bacteria can multiply rapidly in food if left at room temperature or in the "Danger Zone" between 40°F and 140°F. Never leave perishable food out for more than 2 hours (or 1 hour if it's hotter than 90°F outside).
