The storage, handling, preparation and application methods have also been shown to be inappropriate resulting in unacceptable human exposure. Food and other materials are also likely to become contaminated during storage. The majority of farmers handle pesticides without any personal protective equipment and hence exposure is likely to be considerable. During the application process, farmers often inhale the pesticides resulting exposure to respiratory systems. Another possible route of exposure is via the organisms that farmers collect from these environments and used as source of food (i.e., secondary poisoning). These organisms are likely to contain residues of pesticides absorbed from their environments.
