What is Food poisoning?

It is a condition caused by consuming food or water contaminated with infectious biological agents such as bacteria, parasites, viruses, or their toxins.

These harmful organisms can contaminate food from its source and during its processing or preparation, so infection usually occurs after eating or drinking outdoors, in cafes or restaurants, but it can also occur at home, so it is important to verify hygiene when preparing food and not to consume it raw or without any disinfection.

There are diverse contamination sources:

Unpurified water.
Frozen or refrigerated food not stored at the correct temperature.
Food prepared by a person who did not perform proper hand hygiene.
Food prepared using contaminated cookware.
Undercooked or raw meat, poultry, fish, or eggs.
Raw, poorly washed, or not disinfected fruits or vegetables.
Dairy products that have been out of the refrigerator for a long time.

Babies, infants, pregnant women, and older adults are the most susceptible to food poisoning.
