What is Food Poisoning?

Food poisoning is a food-borne disease. Ingestion of food that contains a toxin, chemical or infectious agents like a bacterium, virus, parasite, or prion. They may cause adverse symptoms in the body. Those symptoms may be related only to the gastrointestinal tract causing vomiting or diarrhea or they may involve other organs such as the kidney, brain, or muscle.

Causes of Food Poisoning

It can be caused by the following three factors:

  • Bacteria: Bacteria is the major cause of poisoning.
  • Viruses: The viruses responsible for poisoning include norovirus, rotavirus, and astrovirus. Poisoning through viruses is less common but proves to be fatal. Hepatitis A virus is a serious condition transmitted through food.
  • Parasites: Food poisoning through parasites is very rare. Toxoplasma, a common cause of food poisoning, can be found in cat litter boxes.

During growing, harvesting, and cooking food can be contaminated. The harmful organisms transfer from one surface to the other and result in food contamination. The raw, ready-to-cook food products are more at risk. Since these food items are not cooked, therefore the pathogens are not destroyed resulting in food poisoning.
