| Abstract: | Sulphonamides and chloramphenicol antibiotics were analysed by using liquid chromatography–tandem mass spectrometry (LC-MS/MS) in sea and farmed prawn (Penaeus monodon) samples obtained from the coastal region of southern India during 2011–2012. Average recoveries were 77–99% and precision was between 1% and 8%. The results revealed that in sea prawn samples neither of the two antibiotics was detected, but in farmed samples from coastal Andhra Pradesh some sulphonamides were detected in a concentration range greater than the maximum residual limit as set by Council Directive 2377/90 EC. |
