RESUMO
The article aims to present an overview of pesticide usage and population exposure, focusing on the impact on health and the correlation with food and nutrition security (FNS). This review is relevant due to the extensive use of pesticides in food production, which exposes individuals in various ways, including the ingestion of contaminated food, with adverse health effects. Brazil is one of the largest consumers of pesticides in the world, with product sale growth above 200% from 2000 to 2013, increasing the predisposition of the population and environment to the impacts caused by these compounds. The country has weaknesses regarding the monitoring of pesticide usage, besides its vulnerable population affected by social and economic problems. Studies on the correlation between pesticides and diseases have shown potential health risks, including birth defects, hearing loss, cancer, and infertility, in addition to symptoms related to acute intoxication, such as weakness, vomiting, seizures, difficulty breathing, loss of appetite, and nosebleed, among others. Reduction policies in pesticide usage and the encouragement for the sustainable agricultural practices should be prioritized by public managers. It is also essential to improve the monitoring and surveillance programs and research on the topic, as well as training of health professionals to identify and report the cases of pesticide poisoning.
