What causes food poisoning?

You can have food poisoning if you eat contaminated food or drink contaminated water. During processing or production of food, food can be contaminated at any point such as growing, harvesting, processing, storing, shipping or preparing. The transfer of harmful organisms from one surface to another is often the cause. If you eat that aren’t cooked like salads or other produce, harmful organisms aren’t destroyed before eating and can cause food poisoning.

Many bacterial, viral or parasitic agents are also responsible for food poisoning. Viruses is the leading cause, then the bacteria.

Toxins is another thing to blame. They can be either produced by bacteria on or in food or produced by plants and animals/fish or other organisms that are ingested. Besides, toxin can also be certain chemicals that may cause food poisoning.
