Resumen
The use of veterinary drugs a pesticides in a manner not specified in some stage of livestock production can not only be a waste of resources a capital, but mainly, a situation likely risk of environmental contamination a public health. Faced with this concern, milk samples were collected in northeastern Rio Grande do Sul, the collection of milk for residue analysis were collected monthly from February to June, August, September a November 2011, while the samples for analysis quality of milk, collected monthly from February to September 2011, we evaluated criteria such as: Waste of Veterinary Drugs a Pesticides, Total Bacterial Count, somatic Cell Count, acidity, freezing point, density, total dry extract is degreased, Fat, Lactose , pH, Protein, Temperature. Were found active ingredients of pesticides a veterinary drugs, showing the fragility of the evaluation systems of milk produced, because they were not a are not detected in the tests required by the Ministry of Agriculture, Livestock a Supply (MAPA), the Dairy Industry. The physical-chemical analysis of milk samples are mostly within the standards established by law, while the samples show problems in the sanitary conditions of milk, due to the high total bacterial count (CBT) found in samples. The high somatic cell count (CCS) in milk indicate deficiencies or lack of management treatments.
