An official pesticide monitoring programme checks pesticide residues in the UK food and drink supply, to ensure that there aren't any unexpected residues, to check that residues are not more than the maximum residue levels (MRLs), and to provide an extra check that pesticide residues are not posing a risk to people's health.

This programme is overseen by the independent Pesticide Residues Committee (PRC), which advises the Government. Details of the monitoring programme can be found at:
