Crops can absorb pesticide during growth. The food might then be used in its natural state or used to produce food products to humans and animals. Either way, the pesticides find their way into human foods and can cause illness. Poisoning can occur also from consumption of fish caught in waters contaminated with chemicals.
Chemical poisoning
