QuEChERS highlights
Compared with traditional solid phase extraction and other methods, the QuEChERS method is fast, efficient, environmentally friendly, stable and durable, and has been used in animal-derived foods including antibiotics, pesticides, and illegal drugs. With the further development and improvement of the QuEChERS method, it will become the most convenient and commonly used method in the field of drug residue analysis in the future.

Detection of drug residues in foods of animal origin
At present, there are hundreds of drugs that may have residual risks in the livestock and poultry and aquaculture processes, so there is an urgent need to establish an efficient, simple, stable, and reliable detection method. The QuEChERS method is a promising choice for solving this problem.
Veterinary medicine can prevent and treat animal diseases and is widely used in livestock and poultry farming. Its residue in animal food will bring greater risks to food safety. The public report on the detection of veterinary drug residues in animal tissues using the QuEChERS method was first seen in 2005. Fagerquist et al. used the QuEChERS method to detect β-lactam antibiotic residues in cattle kidneys. Water and acetonitrile were used as extraction reagents, and C18 was used as an adsorbent for fast removal and then analyzed by liquid chromatography-tandem triple quadrupole mass spectrometry (LC-MS / MS).

Pérez-Burgos et al. found that beef samples were extracted by the QuEChERS method, and then added C18, PSA, and MgSO4 for d-SPE adsorption purification. Finally, the LC-MS / MS was used to analyze and detect cephalosporin antibiotics. The results show that, compared with the traditional SPE method, the new method has higher sensitivity and can meet the requirements of relevant EU regulations.
Antiparasitic drugs
Antiparasitic drugs are also commonly used in livestock and poultry farming, and their residual animal-derived foods will also cause great harm to human health, so they need to be included in the scope of supervision and testing. Kinsella et al. used a modified QuEChERS method to detect the insect repellent monetil and its sulfone derivatives in lamb and goat milk. A one-step enrichment process was added to the method to improve sensitivity. Graded mass spectrometry (UPLC-MS / MS) analysis showed that the recovery rates of the two targets were 108% -109%, and good chromatographic separation results were obtained within 13 minutes.
