- Viruses such as norovirus and rotavirus
- Parasites such as Cryptosporidium and Giardia
- Toxins produced by bacteria such as Clostridium botulinum, which causes botulism, or marine organisms such as shellfish containing toxins.

But generally, the food poisoning incubation period ranges from a few hours to several days. Here are some causes and their typical durations:
- Campylobacter – 2 to 5 days
- Cryptosporidium – 2 to 10 days
- coli – 3 to 4 days
- Giardia lamblia – 1 to 2 weeks
- Hepatitis A – 15 to 50 days
- Norovirus – 1 to 2 days
- Rotavirus – 1 to 2 days
- Salmonella – 6 hours to 6 days
- Sapovirus – 1 to 3 days
- Shigella – 1 to 2 days
- Trichinella – 1 to 2 days
- Vibrio vulnificus – 2 to 48 hours
In general, most cases of food poisoning last a few days to a week. However, some cases can last longer.
Factors Affecting the Length of Food Poisoning
- Age: Young children, older adults, and people with weak immune systems may experience more severe symptoms and have a longer recovery time.
- Type and amount of contaminant: Some types of bacteria, viruses, parasites, or toxins are more virulent than others, and a higher dose of contamination can lead to more severe symptoms and a longer duration of illness.
- Overall health: Generally healthy people may recover more quickly from food poisoning than those with underlying health conditions.
- Treatment: In some cases, antibiotics or other medical treatments may be necessary to treat the infection and speed up recovery.
What To Do If You Have Food Poisoning
If you or someone you know has food poisoning, the following self-care measures can help alleviate symptoms and promote recovery:
- Stay hydrated: Drink plenty of clear fluids such as water, broth, or electrolyte drinks to replace fluids lost through diarrhea and vomiting.
- Rest: Get plenty of rest to help the body recover.
- Avoid solid foods: Avoid solid foods until vomiting and diarrhea have subsided. Once symptoms improve, gradually reintroduce bland, easy-to-digest foods such as toast, rice, or bananas.
