Common Causes and Timelines
Many different germs and toxins can cause foodborne illnesses. Here’s a table outlining common culprits, the typical time it takes for symptoms to appear, and common sources of contamination:

| Listeria (bacterium) | 9 to 48 hours (digestive); 1 to 4 weeks (systemic) | Hot dogs, luncheon meats, unpasteurized milk, soft cheeses from unpasteurized milk, refrigerated smoked fish, refrigerated pates/meat spreads, fresh fruits/vegetables. |
| Norovirus (virus) | 12 to 48 hours | Shellfish, fresh fruits/vegetables, ready-to-eat foods touched by infected food handlers, food/water contaminated with vomit/feces. |
| Rotavirus (virus) | 18 to 36 hours | Food, water, or objects contaminated with the virus. |
| Salmonella (bacterium) | 6 hours to 6 days | Poultry, eggs, dairy products, fresh fruits/vegetables, meat, nuts, spices. |
| Shellfish poisoning (toxin) | Usually 30 to 60 minutes | Shellfish from coastal seawater contaminated with toxins. |
| Shigella (bacterium) | Usually 1 to 2 days | Contact with a sick person, food/water contaminated with human feces, ready-to-eat food handled by infected food workers. |
| Staphylococcus aureus (bacterium) | 30 minutes to 8 hours | Meat, egg salad, potato salad, cream-filled pastries left out too long or handled by a person with the bacteria. |
| Vibrio (bacterium) | 2 to 48 hours | Raw/undercooked fish/shellfish (especially oysters), water contaminated with sewage, rice, millet, fresh fruits/vegetables. |
How Food Becomes Contaminated
Food can be contaminated at any stage, from farm to table, including growing, harvesting, processing, storing, shipping, and preparing. Contamination can occur due to:
- Poor handwashing: Failure to wash hands properly after using the toilet can transfer contaminants.
- Unclean cooking areas: Unwashed knives, cutting boards, and kitchen tools can spread contaminants.
- Improper storage: Food left at room temperature for extended periods or stored in a refrigerator that is too warm can become contaminated.
Prevention is Key
Preventing food poisoning involves practicing good hygiene and food safety habits:
- Handwashing: Wash hands thoroughly with soap and water for at least 20 seconds before and after handling food.
- Wash produce: Rinse fruits and vegetables under running water before eating, peeling, or preparing.
- Clean utensils: Wash cutting boards, knives, and other utensils with soapy water after contact with raw meats or unwashed produce.
- Cook food thoroughly: Use a meat thermometer to ensure meat is cooked to a safe internal temperature.
- Refrigerate leftovers promptly: Store leftovers in covered containers in the refrigerator immediately after a meal.
- Thaw food safely: Thaw frozen food in the refrigerator, microwave, or in cold water.
- When in doubt, throw it out: If you’re unsure if a food has been safely prepared, served, or stored, discard it.
- Clean your refrigerator regularly: Clean the inside of your refrigerator every few months with a baking soda and water solution.
Conclusion
Understanding how long does it take food to cause diarrhea is essential for identifying the potential source of food poisoning and seeking appropriate treatment. By practicing proper food safety and hygiene, you can significantly reduce your risk of contracting a foodborne illness. If you experience severe symptoms, consult a healthcare professional immediately. Remember that certain populations, such as pregnant women, young children, older adults, and individuals with weakened immune systems, are at higher risk for complications and should take extra precautions.
