Analysis of Pesticide Residues in Foodstuffs
WESSLING offers you a competent team of experts for the analysis and assessment of pesticide residues in food and feedstuffs; using state-of-the-art measuring instruments and methods, they produce reliable results and expert assessments.
Pesticides – Regulation (EC) No 396/2005 and Rückstands-Höchstmengenverordnung (RHmV – German Maximum Residue Level Regulation)
Pesticides, insecticides, preservatives and some other substance groups are generally subsumed under the heading of pesticides. They are frequently used in agricultural production to optimise yield. Residues from this application and their metabolites may remain in food and feedstuffs. The permissible amounts are regulated by statutory maximum levels.
Pesticide residue analysis
The used measuring devices include state-of-the-art GC-MS and LC-MS systems. In contrast to classical detection methods, the use of mass spectrometry detection methods offers additional security and thus ensures matrix-independent, reliable identification and quantification even in complex samples such as tea and spices. This ensures testing of all maximum and guidance levels (such as the orientation level set down by the Bundesverband Naturkost Naturwaren (BNN - German Association of Organic Processors, Wholesalers and Retailers)).
Our pesticide screening (GC + LC) comprises more than 520 active agents and metabolites. The list of active agents is constantly adapted to reflect the latest developments. The service is further complemented by individual methods testing for other active agents as illustrated in the overview at the bottom of this page.
In addition to classical pesticides, increased focus is placed on substances that enter into foodstuffs as contaminants yet at the same time are classified as pesticides, for example, chlorate and quaternary ammonium cations (BAC, DDAC). These 'crossers' place special demands on analysis and assessment.
Assessment and marketability of foodstuffs
A team of food analysts subsequently supports you in the assessment of the marketability of your products and offers you a maximum degree of safety and quality by use of state-of-the-art analysis devices.
The annexes of the Regulation (EC) No 396/2005 on maximum residue levels of pesticide, in force across the EU, specify maximum levels for a large number of active agents. These annexes are constantly revised. Yet also the 'old' German Maximum Residue Level Regulation (RHmV) remains of importance in certain niche areas, such as regarding synergists as well as fish and other marine animals. Special regulations regarding pesticide residues apply to dietary foodstuffs for infants; furthermore, biologically produced foodstuffs are subject to more severe assessments regarding pesticide residues.
In addition to food regulatory standards, the adherence to specifications set out by the food retail industry plays an increasing role. We are happy to extend our assessment to include these upon request.
