Veterinary drugs residues are used within animal husbandry to cure and prevent diseases, and also for weight gain and tranquillise during transportation.

Veterinary drugs are a complex group of substances with a couple of hundred actives belonging to different chemical classes and therapeutic areas, e.g. antibiotics, antiparasitics, non-steroidal anti-inflammatory drugs (NSAIDs), such as phenylbutazone, hormones and, beta-agonists.

The EU Commission as well as regulatory authorities all over the world have established various restrictions on the application of veterinary drugs, ranging from zero tolerance to restrictions on specific animal species and fields of insertion up to tolerable limit values.

AES currently tests the following matrices for veterinary drug residues:

  • Milk and milk products
  • Honey
  • Meat and Meta ProductsVeterinary Drug Residues

Main analytical parameters for drug residue analysis:

Antibiotics and antiparasitics:

  • chloramphenicol
  • avermectins
  • benzimidazoles
  • beta-lactams
  • macrolides
  • aminoglycosides
  • nitroimidazoles
  • sulfonamides
  • tetracyclines
  • nitrofurans and its metabolites

Non-steroidal anti-inflammatory drugs (NSAIDs)

  • phenylbutazone

Analytical Technologies

AES uses latest equipment including LCMSMS techniques for screening and determination of veterinary drug residues in foodstuff.  The analytical methods have been developed and therafter validated using rigorous validation protocols like 657/2002/EC
