Detección de la presencia de antibióticos en canales bovinas faenadas en el camal municipal de la ciudad de Azogues mediante la prueba microbiana premi test

Abstract

The main goal of this study is to detect the presence of antibiotic residues in meat originating from Azogues Municipal Slaughterhouse in a sample of 189 animals. The qualitative microbial test “Premi Test” which determine the presence of 30 types of different antibiotic substances was applied. The results show 155 positive cases, that represents 82% of the total sample. Additionally, the overall prevalence of drug residues unvaried considering the following variables: sex, age (higher and less than five years old), origin (Cañar, Azuay, Morona Santiago and Loja), race (beef pure and cross-bred cattle) and condition (emergency slaughtered calves and apparently healthy ones) was evaluated. The results indicated that the cattle presents antibiotic residues in all the cases. The chi-square test was not significant respect the relationship between age and prevalence variables. We can conclude that the beef presents antibiotic residues independently of the variables, then the meat distributed do not comply with regulatory. Finally, is very important to carry out this type of studies in all the slaughter and distribution places, in order to control this condition and to take appropriate actions to ensure beef safety for consumers
