Pesticide Residues

We have many years experience carrying out pesticides residue testing, providing services across the food supply chain. Our aim is to understand and meet the demands of the customer and to assist with any upcoming and emerging issues. The majority of pesticides can be analysed by multi-residue screening methods, in addition we also offer a range of single residue methods.

Pesticides Report - Quarter 1 2016 Findings

A limited number of foods have been tested for chlorate for the first time in 2016, to provide evidence that it is necessary to review the existing default MRL in order to take account of non-pesticide sources. The pesticide sodium chlorate is a residual broad action weed killer, which is not authorised for use in the EU. Far more likely sources in food are from chlorine-based treatments of drinking and irrigation water as well as chlorine-based surface disinfectants, which are widely used to ensure microbiological safety. This reports highlights with HSE and the FSA that the current MRL needs to take account of these often essential and unavoidable sources.
