Trazabilidad de antibióticos en ganaderías lecheras del cantón El Carmen, Manabí.

Abstract

The present study was carried out in the Wilfrido Loor Moreira parish belonging to the El Carmen canton, in November 2021, in order to determine the traceability of antibiotics in dairy farms in the parish. A non-probabilistic sampling was carried out in a population of 40 producers and a sample of 26 producers was determined. To avoid false positives, the acidity test was applied by means of the Alcohol Test, the samples were kept refrigerated and processed in the laboratory of the Río Suma Experimental Farm of the ULEAM Extension in El Carmen. At 24 hours, the yogurt inhibition test was performed to determine the existence of traces of antibiotics in milk. The identification of the pharmacological groups was carried out with the AuroFlowTM BTS Combo Strip Test Kit, designed for the detection of beta-lactam antibiotics, tetracyclines and sulfonamides. The risk factors associated with traceability were established by calculating the Odd's Ratio using the On line WINEPI software from winepi.net. The percentage residuality of antibiotics was 0 % for all farms evaluated and 100% of the samples were negative for the pharmacological groups tetracycline, beta-lactams and sulfonamides. It was possible to determine that there is no association between the risk factors and the traceability found. This is because the Odds Ratio statistical association measure reached null values = (1) for a significance level of 95% in all survey responses.
