According to the European Pesticide Residues Committee, apples, peas, and grapes are sometimes covered in crop spray that is above the maximum levels allowed under EU law. The findings come from tests of more than 4,000 samples of food and drink.
The levels of pesticides varied considerably, with imported fruit and vegetables tending to have higher levels.
One in seven beans in a pod and one in five yams all had pesticides above the allowed level. One in 70 apples and pears had illegal levels of pesticides.
All of the vegetables and fruits supplied to schools contained pesticides within allowed levels, though nearly all the apples and every one of the bananas had some form of pesticide in them. Many of the pieces of fruit had more than one pesticide.
