A recently published study by the University of Brazil defines the extent of DNA damage suffered by farmworkers exposed to the daily applications of fungicides, herbicides and insecticides. A total of 127 individuals, 81 exposed and 46 non-exposed controls, were evaluated. Comet assay and BMCyt (micronuclei and nuclear buds) data revealed DNA damage and cell death in soybean workers. Higher concentrations of Mg, Al, Si, P, S, and Cl were observed in cells from workers. No associations with use of personal protective equipment, gender, or mode of application of pesticides were observed.
This study once again raises the issue of DNA toxicity associated with the consumption of herbicide resistant genetically modifed organisms. Monsanto is the leading producer of herbicides, including glyphopshate, and genetically modified organisms resistant to herbicides.
