Effects of occupational exposure to glyphosate in winegrowers

Glyphosate is a non-selective systemic herbicide used in agriculture. For almost half a century, the International Agency for Research on Cancer has run a Monographs program, the conclusion in March 2015 that glyphosate is “probably carcinogenic to humans†in addition to being genotoxic and carcinogenic in animals, while the regulatory European Food Safety Authority have asserted that glyphosate poses no public risk. The scientific debate is still lively. We collected detailed socio-demographic, occupational exposures and health surveillance information for 26 winegrowers as aim to investigate exposure to glyphosate and other pesticide. Exposure was assessed through biological monitoring (24-hour urine collection), immune function (IL-4, IL-5, IL-8, IL-12, IL- 17, IL-33, IFN- γ), transcriptional and post transcriptional alterations (miRNA) and genotoxic effects (Comet assay). The exposure conditions in our winegrowers, as referred to the parameters so far analyzed, did not reveal a significant glyphosate absorption nor significant health concerns.
