    (2015) Castillo Zumba, Paola Fernanda; Ortega Echeverría, Renato Esteban; Vaca Vaca, Carlos Miguel
    This study was conducted in the Cuenca Canton in the province of Azuay in carriers who collect raw milk from the farms of Tarqui and lead them to the processing plant or sell it directly. The sampling was carried out with the support of AGROCALIDAD/Azuay and National Police in raids in strategic positions. 90 samples of 39 carriers registered parish was collected and with permit operation of AGROCALIDAD/Azuay representing 100% of the population studied. Established parameters were determined by the Standard INEN 9 as protein stability, pH, presence of antibiotics, peroxides and neutralizing; the methodology used is based on the Manual of Procedures for Surveillance and Control of Raw Milk Safety (AGROCALIDAD, 2013), two tests (presence of neutralizing and pH) were performed at the Laboratory for Rapid Diagnosis of AGROCALIDAD/Azuay. It was determined that 35.5% of samples do not meet the parameters established by the competent authority, of which, 10% presented acid pH, 10% protein instability, 4.4% presence of antibiotics and 11.1% with neutralizing. Correlation statistical methods were established where it is observed that the higher the travel time there are more chances that the pH drops, and carriers that have more suppliers there is greater chance that milk contaminated with antibiotics is found.
