Dietary exposure assessment of tetracycline residues in milk in Haryana

Abstract

In addition to biological hazards i.e. bacteria, viruses, parasites, the occurrence of antimicrobial residues in food is another characteristic of modern food production. The use of veterinary drugs is more in production of animals so it is difficult to avoid the harmful effects in the presence of their residues in food. This study was conducted to determine dietary exposure risk to tetracycline residues in milk consumed in the Hisar city. The risk was assessed on the basis of per capita availability of milk in Haryana and India by calculating hazard quotient for each analyte under study. The results of risk assessment due to dietary exposure to the residues through milk consumption in India showed hazard quotient of 0.009, 0.004, 0.002 for oxytetracycline, tetracycline, chlortetracycline. These results revealed no toxicological risk with regard to dietary exposure of tetracycline residues through milk.
