Quinolone antibacterials are veterinary drugs authorized for use in food animal production. The analysis of residual amounts of drugs in food from animal origin is important for quality control of products for consumers. For this purpose, Maximum Residue Limits (MRLs) have been set up by a European Union Council Regulation on Veterinary Drug Residues (No.

An analytical method for the determination of OTC and TC residues in honey was developed. Sample treatment involves an extraction in EDTA-McIlvaine buffer, followed by a solid-phase cleanup step. With regard to the cleanup procedure, different SPE cartridges were evaluated and the results presented.

The effect of an organophosphorus (OP) insecticide, methyl parathion on the behaviour of a freshwater air breathing teleost fish, the Climbing perch, Anabas testudineus was studied. The breathing rate, rate of feeding, performance of sustained swimming behaviour against water current and the learning ability were severely curtailed in the fish exposed to 5 mg/L of methyl parathion.

A method using liquid chromatography electrospray ionization tandem mass spectrometry (LC/ESI-MS/MS) for the determination of trace levels of five macrolide antibiotics (spiramycin, tilmicosin, oleandomycin, erythromycin, and tylosin) in eggs is presented.

A simple and rapid analytical method was developed for the determination of lincomycin and tylosin residues in honey as part of field studies examining the efficacy and target animal safety of these antibiotics to control American foulbrood disease in honey bees.

In the present investigation, an attempt has been made to study the genotoxic effect of commonly used pesticides of South India, like 2,4-D, lindane, sevin and phosphamidon, in the human lymphocytes by comet assay and chromosomal analysis.
