Occurrence of antibiotics in animal sourced foods not only affects economy but also poses potential health risks. The present study aimed to validate simultaneous detection of amoxicillin, penicillin – G and enrofloxacin in raw migratory goat milk (N=223) by HPLC-DAD and assess human health risks in Western Himalayan region, India.

A national survey of sixteen commonly used antibiotics in chicken meat was conducted for three consecutive years (2016–2018). A total of 4591 chicken meat samples were collected from 24 provinces in China and measured by ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The results revealed that all of the antibiotics studied were detected with an overall detection frequency of 20.47% and an exceeding standard rate of 2.94%.

To assess the health risks from antibiotic residues in freshwater fish, this study analyzed residues of 65 antibiotics in 10 freshwater fish species sampled in southeast China. Eight antibiotics were detected by UPLC-MS/MS at an overall detection rate of 53.9%, with 3.48% of samples exceeding MRLs and 13.0% suggesting the misuse of human antibiotics. Quinolones, particularly enrofloxacin, were the most frequently detected residues.

Fluoroquinolones are widely employed to treat or prevent respiratory diseases in poultry, and their residues could be present even after slaughtering. Thus, this study aimed to assess the oxidative effect of fluoroquinolones on myosin and chicken meat proteins under in vitro conditions, using proteomics and peptidomics approaches.

A novelty high-throughput semi-automatic sample clean-up method was developed and used for rapid analysis of 9 drug residues in fish muscle tissues combined with high-performance liquid chromatography/quadrupole-linear ion trap mass spectrometry (HPLC-QTRAP-MS/MS). The target compounds were extracted by Quick, Easy, Cheap, Effective, Rugged and Safe multiresidue (QuEChERS) method with acetonitrile. A vortex oscillating clean-up column was proposed for single step purification firstly.
