Pesticides are widely used globally. They provide important benefits in public health and food production and are an effective and economical method to enhance yield quality and quantity, thus ensuring food security worldwide.2 However, because pesticides are designed to impact biological systems, concerns have been raised regarding potential health impacts from widespread pesticide use.2 Indeed, exposure to some classes of pesticides has been associated with many adverse health outcomes, both of the general population and among occupationally exposed workers.2 Nevertheless, the benefits of pesticide use should be considered together with the potential health effects and its social and economic consequences resulting from exposure to pesticides for millions of exposed farmers and rural communities, especially in lower income countries.
