Milk is a highly perishable food product. Among the factors responsible for changes in composition and physicochemical properties of milk, worth mentioning those resulting from mastitis. The presence of high somatic cells in milk is associated with changes in concentrations of milk minerals, affecting the quality. The objective of this study was to evaluate the interference of somatic cell count (SCC) in the presence and absence of chloride in fresh milk. There were two tests in a span of 15 days, with analysis of CCS conducted research and chlorides. The results of the first sample showed that 43.75% were positive for chloride, and 71.43% related to CCS over 300mil, and 28.57% with interference from other factors. In the second collection chloride 37.50% were positive, 75% related to CCS over 300mil, and 25% related to other interferences. The presence or absence of chloride in milk from cows, is not associated with fraudulent actions. The Survey of chlorides can not be considered a reliable method for diagnosis of clinical mastitis due to false positive results. |
