Our services in the analysis of residues and contaminants

We examine food and feed as well as environmental samples for different pollutants. A distinction is often made between residues and contaminants. 

Residues are residues of substances that have been specifically used during the production of food. These include pesticides and pharmaceuticals used in veterinary treatments. 

Contaminants are impurities that are not deliberately used, but unintentionally enter the food. These include, but are not limited to

  • Nitrate from vegetable raw materials
  • Acrylamide from heated foodstuffs
  • Melamine from contaminated food and feed raw materials
  • 3-MCPD / 3-MCPD ester from finishing processes
  • Mineral oil hydrocarbons (MOSH/MOAH) from packaging
  • Residues of solvents (e.g. dichloromethane, n-hexane)
  • aromatic hydrocarbons such as BTEX or benzene, toluene, ethylbenzene, xylenes and styrene
  • Highly volatile halogenated hydrocarbons (LHKW)
  • Organotin compounds
  • polybrominated diphenyl ethers (flame retardants)
  • polyfluorinated surfactants (PFT) made of extinguishing foam
  • chlorinated naphthalenes
  • chlorbenzenes
  • Algae toxins (microcystins)

For all substances mentioned we carry out content determination in our laboratories.

The setting of maximum levels is done, inter alia, in the Regulations:

  • Regulation (EC) No 1881/2006 setting maximum levels for certain contaminants in foodstuffs (as last amended by Article 1 of Regulation (EC) No 165/2010 amending Regulation (EC) No 1881/2006; Contaminant Maximum Level Regulation)
  • VO (national) zur Begrenzung von Kontaminanten in Lebensmitteln vom 19. März 2010 (Contaminants Ordinance; KmV)
  • Regulation (EC) No 396/2005 on maximum residue levels of pesticides in or on food and feed of plant and animal origin
  • Maximum Residue Amount Ordinance (RHmV)
  • Guidance value for plant protection products, chemically synthetic pesticides and chemically synthetic stock protection products (BNN, 2001)
