| Sumario: | Intensified dairy production systems generate animal excreta concentration that\nimpact on the accumulation of nutrients, pathogenic microorganisms and veterinary\ndrug residues that have an incidence over contamination of different water sources.\nEnvironmental and sanitary consequences of primary milk production intensification\nprocesses in Argentina were evaluated. Inquiries into water use and management,\neffluent management and impact and the use and impact of antibiotics were made.\nGroundwater contamination by nitrates and microorganisms were determined to be\npresent in the entire region, increasing when shallow aquifers, permeable soils and\ndeficient well construction are present. The existent effluent treatment systems are\ninefficient, and different practices associated with excreta and animal feeding\nmanagement, were identified to affect chemical and microbial quality in water\nsources in critical sectors._Antibiotic use was not detected to be troublesome; in\ngeneral, however, feed pads were identified as sectors that accumulate their residues.\nAntibiotic resistant bacterial strains were isolated from liquid effluents. An early and\nintegral approach of these problems should avoid environmental and sanitary impacts\nthat affect the health of the population. |
