Detection of adulteration of dairy products with vegetable fats using the method of luminescent analysis

Abstract

This article describes a technique for detecting pesticides in poultry meat samples using thin layer chromatography. In the course of the study, the qualitative indicators of the content of pesticides in samples of poultry carcasses treated with the insecticide esbiotrin, used to prevent the reproduction of the red chicken mite among the poultry population, were determined. The studies were carried out at various time intervals from the moment the poultry was treated with the drug; quantitative determination of the content of the residual concentration of pesticides by thin-layer chromatography will reveal the feasibility and safety of using the active substance as an insecticide in poultry farming. Chromatographic studies were carried out on the basis of the Department of Veterinary and Sanitary Expertise of the SPbGUVM.

During the experiment, 3 experimental groups of laying hens and 1 control group (10 animals each) were selected. The experimental groups were treated with a 0.001% solution of esbiotrin after which the birds were slaughtered 24, 72 and 120 hours after treatment. The selected samples were subjected to chromatographic examination to detect residual concentrations of synthetic pyrethroids.
