##Insecticides-As the most widely used agricultural chemicals represent the greatest risk to food contamination of this category. Some are extremely environmentally stable & toxic.

###Chlorinated Hydrocarbons<br>DDT (Dichloro-Diphenyl-Trichloroethane) is th most well known. It is very durable, accumulates in tissues & persists in the environment. Chlorinated Hydrocarbons are CNS stimulants & cause congestion of internal organs & focal centrilobular necrosis of the liver.

###Organophosphates<br>The most widely used insecticides, are much less persistant in the environment & body tissues than Chlorinated Hydrocarbons and hence, present less of a risk. They can however, be extremely toxic to mammals causing non-specific acute signs or chronic lung congestion. They may be an Occupational Hazard.
