About 70% of fresh produce sold in the US has pesticide residues on it even after it is washed, according to a health advocacy group.
According to the Environmental Working Group’s annual analysis of US Department of Agriculture data, strawberries, spinach and kale are among the most pesticide-heavy produce, while avocados, sweetcorn and pineapples had the lowest level of residues.
More than 92% of kale tested contained two or more pesticide residues, according to the analysis, and a single sample of conventionally farmed kale could contain up to 18 different pesticides.
Dacthal – the most common pesticide found, which was detected in nearly 60% of kale samples, is banned in Europe and classified as a possible human carcinogen in the US.
