Range of Services Residue Analysis

Plant protection products are widely used in agriculture. They are intended to prevent crop losses due to pest infestation, to ensure the quality of plant products, or to reduce the growth of weeds. As a food manufacturer or retailer, you want to know if pesticide residues are included in your products. You must ensure that the proven pesticides comply with the legal requirements in the EU and in Germany.

Legal basis

For numerous pesticide active substances and their metabolites or degradation products, European Council Regulation (EC) No. 396/2005 regulates maximum residue levels (MRLs), which must be strictly adhered to when these substances are used. The national regulations of the ordinance on maximum residues cover further substances like herbicide safeners and synergists.

In addition to compliance with the maximum pesticide levels in conventional goods, the examination of products from certified organic farming is becoming more topical. The legal assessment of such products is carried out in accordance with the EU Organic Farming Regulation and on the basis of the specific tolerance values of national and international organic associations.

Related terms

The terms plant protection agents and pesticides are often used interchangeably. The chemical or biological agents are widely used as insecticides, herbicides, acaricides, growth regulators, or fungicides. In addition to the known types of pesticides, there are many more, such as biocides, nematicides or germ inhibitors.

Technology and reliability of the analytics

In addition to the accreditation according to DIN EN ISO ISO/IEC 17025, regular participation in interlaboratory tests is an integral part of our quality assurance. The pesticide laboratory of SGS Institut Fresenius participates annually in a large number of such performance tests from various recognized providers, as well as in the QS laboratory competence test, comparative laboratory tests and the BNN interlaboratory test. The active cooperation in committees and associations serves the harmonization of methods, the establishment of new procedures and the exchange of complex legal questions:

Maximum residue limits for food exports to China

A new GB standard came into force in September 2021. It sets maximum residue limits (MRLs) for 564 pesticides in food products to be sold in the Chinese market. The GB2763-2021 standard replaces the 2019 standard, and the new version includes additional 81 pesticides. MRLs have also been set for some pesticides that are not registered in China but may be present in imported products.

Therefore, new detection methods for animal products and vegetable oils and fats have been developed in our laboratories. For food manufacturers who want to export their products to China, our laboratories offer a comprehensive range of analyses that meet the requirements of the new GB standard.
