Causes of Food Poisoning

There are about 250 diseases that could be transmitted through food. According to the CDC, 81% of unknown agents cause all the food borne infections. Many cases are not reported because the symptoms are mild and they recover quickly. The food poisoning causes can be put into two groups. They are:


Toxic agents like poisonous mushrooms, preparing exotic foods in an improper manner like barracuda or the use of pesticides on vegetables and fruits.


Infectious agents like bacteria, viruses and parasites.

Food poisoning can also be caused due to contamination that occurs from poor preparation of food and poor sanitation. It can also be due to food handlers, who do not wash hands after using the bathroom. Even if the food handlers have infections then the food they prepare gets contaminated. If the food stored is not packed properly or if they are stored at the wrong temperatures. These also promote contamination and cause food poisoning.
