Abstract

The determination of antibiotic sulfonamide residues and raw milk quality control was carried out in THREE cattle farms of three cantons ( Chambo, Riobamba and Guano) of the Chimborazo province; for this a Latin Square Design was used, finding the presence of antibiotics and sulfonamides in the cattle farms of Riobamba and Guano in December (33 and 67%), while in January they were present in the cattle farms of Riobamba and Chambo (67% in each) and in February in the cattle farms of Chambo and Guano, 33% in each; as to the physical and chemical features 6.46 pH and 1.03 density were determined; the presence of mesophyll aerobes and fecal coliforms was evident in a high content of 7.71X104 to 1.07X105; as to the color, odor, flavor and acceptance values of 4.22, 3.70, 3.64 and 3.54 points were recorded accumulating a total of 15.13/20; it is concluded that the presence of antibiotics and sulfonamides in the raw milk in December, January and February was evident; in general these pharmacological residues do not influence on the milk acceptance.
