What is DDT and why was it banned?

In 1972, EPA issued a cancellation order for DDT based on its adverse environmental effects, such as those to wildlife, as well as its potential human health risks. Since then, studies have continued, and a relationship between DDT exposure and reproductive effects in humans is suspected, based on studies in animals.

Is DDT good for humans?

Human health effects from DDT at low environmental doses are unknown. Following exposure to high doses, human symptoms can include vomiting, tremors or shakiness, and seizures. Laboratory animal studies showed effects on the liver and reproduction. DDT is considered a possible human carcinogen.

In September 2006, the World Health Organization (WHO) declared its support for the indoor use of DDT in African countries where malaria remains a major health problem, citing that benefits of the pesticide outweigh the health and environmental risks.

What are biomonitoring studies of DDT and DDE?

Biomonitoring studies of serum DDT and DDE can provide physicians and public health officials with reference values so that they can determine whether people have been exposed to higher levels of DDT and DDE than are found in the general population.

How can I remove DDT from my food?

Washing fruit and vegetables will remove most DDT from their surface. When cooking fish, remove the fish skin and visible fat, and then broil, grill, or bake the fish so the fat drips off. Learn more about reducing your exposure to contaminants in fish.
