Symptoms of foodborne illness vary depending on the specific pathogen involved but typically include one or more of the following: nausea, vomiting, diarrhea, abdominal pain, fever, and malaise.


  • Key measures for preventing foodborne illnesses involve proper food handling and preparation practices:
  • Cleanliness: Washing hands and surfaces regularly.
  • Proper cooking: Ensuring foods reach an internal temperature that kills potential pathogens.
  • Avoiding cross-contamination: Separating raw and cooked foods.
  • Safe storage: Refrigerating foods promptly.


Treatment of foodborne illness often involves symptom management, with hydration and rest being paramount. In severe cases, or those caused by certain pathogens, antimicrobial medications may be required.


Foodborne illnesses are a significant public health issue worldwide, with millions of cases occurring annually.
