Food poisoning is an illness caused by eating foods that have harmful organisms in them. These harmful germs can include bacteria, parasites, and viruses. Food poisoning is a common, usually mild, but sometimes deadly illness. Typical symptoms include nausea, vomiting, abdominal cramping, and diarrhea that occur suddenly (within 48 hours) after consuming a contaminated food or drink. You must admit, at some stage in yout life you have suffered food poisoning, but what is it and what causes it?
Causes: The known causes of food poisoning can be divided into two categories: infectious agents and toxic agents.

- Infectious agents include viruses, bacteria, and parasites.
- Toxic agents include poisonous mushrooms, improperly prepared exotic foods (such as barracuda), or pesticides on fruits and vegetables.
- Food usually becomes contaminated from poor sanitation or preparation. Food handlers who do not wash their hands after using the bathroom or have infections themselves often cause contamination. Improperly packaged food stored at the wrong temperature also promotes contamination.
