Despite its widespread use, there is currently little monitoring of glyphosate in food, water or the wider environment. Last year, Friends of the Earth (FoE) and GM Freeze commissioned a study based on urine samples from volunteers in 18 countries across Europe [2]. It found that on average 44 percent of samples contained glyphosate. The proportion of positive samples varied between countries, with Malta, Germany, the UK and Poland having the most positive tests, and lower levels detected in Macedonia and Switzerland. All the volunteers who provided samples lived in cities, and none had handled or used glyphosate products in the run-up to the tests. The study was the first time monitoring has been carried out across Europe for the presence of the weed killer in human bodies.
