Chemical and Pharmaceutical Residues

Veterinary medicines are often used in animal husbandry to treat and prevent disease, promote weight gain and calm animals during transportation. These class of drugs includes antibiotics, antiparasitics, anti-inflammatories and growth promoters, among others. 

Their extensive use in livestock raises serious concerns, since their presence in food products can have significant adverse consequences for human health. These include hepatotoxicity, nephrotoxicity, unwanted side effects, allergic reactions, sterility, cancer and the possibility of contaminated food contributing to antimicrobial resistance. It is therefore essential to strictly monitor and regulate the use of these medicines to guarantee food safety and protect public health.

We offer a wide range of products for the direct search for contaminants and their subsequent purification:

• • Lateral Flow Strips for the detection of antimicrobials - Quinolones, Lincomycin, Sulfonamides, Tetracyclines, Beta-lactam, Erythromycin, Tylosin, Florfenicol, Chloramphenicol, Neomycin, among others.
  • QuEChERS for the extraction of pesticides and their detection in food

QuEChERS was introduced for the analysis of pesticide residues in fruit and vegetables, but has been gaining popularity in the analysis of a broad spectrum of matrices such as veterinary drugs and other pharmaceutical products, mycotoxins, dyes, acrylamide, biphenols, endocrine disruptors and other chemical compounds.

The wide range of applications of this technique is made possible by the use of different extraction solvents, salt formulations and buffer additives in the salt partitioning step, which concentrate and purify the desired compounds. At the same time, the application of various d-SPE (dispersed solid phase extraction) adsorbents in the clean-up step helps to remove interferents prior to analysis.
