Estudio preliminar sobre el uso de la técnica Elisa competitiva para la detección de residuos de Ivermectina en hígado de bovinos

Abstract

Parasitic diseases are considered one of the most important problems affecting cattle producers in Colombia. The use of antiparasitic drugs like Ivermectin is common as a therapeutic strategy. The presence of this active component in milk and meat generates problems of public health concern. This study was conducted to evaluate the competitive ELISA technique as a method for ivermectin residues detection in cattle livers obtained of a slaughtering plant located in the Sabana of Bogota. Of 50 analyzed samples, 74% (37/50) were considered without residues, 26 %( 12/50) presented residue levels below the maximum allowed limit and 2% (1/50) exceeded the maximum residually level. The used technique proved to be an alternative, fast, sensitive and cheaper screening method for Ivermectin residue detection.
