The herbicide glyphosate – the most widely used herbicide on the planet – is authorised for use in the EU until December 2022. The EU is currently assessing whether its licence should be renewed.
Washington State University (WSU) researchers have found a variety of diseases and other health problems in the second- and third-generation offspring of rats exposed to glyphosate. In the first study of its kind, the researchers saw descendants of exposed rats developing prostate, kidney and ovarian diseases, obesity and birth abnormalities.
Michael Skinner, a WSU professor of biological sciences, and his colleagues exposed pregnant rats to the herbicide between their eighth and 14th days of gestation. The dose – half the amount expected to show no adverse effect – produced no apparent ill effects on either the parents or the first generation of offspring.
