What you need to know

Pharmaceutical and veterinary are essential for To facilitate the fair trade of food, and to ensure a consistent human and welfare, but their use can leave residues and evidence-based approach to consumer protection across in both the food chain and the environment. In a 2019 survey the globe, the Codex Alimentarius Commission (“Codex”) was of EU member states, the European Food Safety Authority established in 1963. Codex is a joint agency of the FAO (Food (EFSA) found that the number one food safety concern was and Agriculture Office of the United Nations) and the WHO the misuse of , and in farm (World Health Organisation). It is responsible for producing . This is, in part, related to the issue of growing and maintaining the Codex Alimentarius: a compendium of resistance in humans as a result of their potential overuse in standards, guidelines and codes of practice relating to food animals. This level of concern and increasing awareness of safety. The legal framework for the authorisation, distribution the risks associated with veterinary residues entering the food and control of Veterinary Medicinal Products (VMPs) varies chain has led to many regulatory bodies increasing surveillance from country to country, but certain common principles activities for pharmaceutical and veterinary residues in food and apply which are described in the Codex guidelines. water supplies.

For example, the EU Directive 96/23/EC sets out the requirements for residue monitoring plans and establishes On the following pages you will the range of substances to be tested in live animals and find our extensive selection of animal products. In addition, each EU member state must have a National Residue Control Plan (NRCP). NRCPs are targeted pharmaceutical and veterinary surveillance testing designed to police the correct use of reference materials, including where veterinary medicinal products. Non-EU countries exporting available the parent compounds, food to the EU must implement monitoring programmes which comply with equivalent food safety levels. associated metabolites and stable labelled (SIL) compounds. In China, the Ministry of Agriculture Announcement No. 235 (中华人民共和国农业部公告第235号) sets out the requirements for residue monitoring plans and establishes the range of Visit lgcstandards.com/ substances to be tested in live animals and animal products. drehrenstorfer to explore the The government also sets National Food Safety Inspections full and extensive range of over (国家食品安全监督抽检) every year to police the correct use of veterinary medicinal products to ensure food safety.

With all measurements on our certificate of analysis carried out in accordance with ISO 17025 and a majority of products Testing the active is often not sufficient, since they are produced under the scope of our ISO 17034 accreditation, metabolized into other biologically active substances. As more we guarantee the highest quality reference materials for your research is conducted in this area, metabolites are increasingly analytical testing. being written into regulations with specific maximum residue limits, necessitating testing. SIL compounds can be added to samples to negate the ‘matrix effects’ often observed with mass spectrometric techniques such as LC-MSMS, further ensuring the reliability of your analysis.
