Food poisoning is one of the most common health problems worldwide and can affect anyone, regardless of age. It occurs after consuming food or beverages contaminated with harmful bacteria, viruses, parasites, or toxins.
While many cases are mild and resolve within a few days, some can become serious, especially for young children, older adults, pregnant women, and people with weakened immune systems.
In this guide, we’ll explain the symptoms of food poisoning, available treatments, prevention tips, and when to seek medical care.
What Is Food Poisoning?
Food poisoning is an illness caused by eating contaminated food or drinking contaminated water. Contamination can occur during food preparation, storage, transportation, or handling.
Common causes include:
- Bacteria such as Salmonella, E. coli, and Campylobacter
- Viruses such as Norovirus
- Parasites
- Food toxins
- Poor food hygiene
Symptoms can appear within a few hours or several days after consuming contaminated food.
Common Symptoms of Food Poisoning
The severity of symptoms varies depending on the cause and the person’s overall health.
The most common symptoms include:
- Nausea
- Vomiting
- Diarrhea
- Stomach cramps
- Abdominal pain
- Fever
- Headache
- Weakness and fatigue
- Loss of appetite
Most people recover within 24 to 72 hours, although some cases may last longer.

Seek medical care if you experience:
