Resumen:
n recent years, goat´s milk has shown a number of advantages over the milk from other ruminant species. Some milk substances can alter the milk quality and also present potential carcinogenic activity. In this work, chemical composition and mutagenic compounds were determined using Ames test on goat milk from different geographical locations of northern Argentina. In Tucumán, two extensive farms were analyzed, one of them near to soybean culture, La Perla Farm, where the goat́s milk showed 788 ± 33 colonies/plate and the Sunchales Farm, which milk contained 655 ± 51 colonies/plate. The third is a public organization with semi-extensive INTA Farm, where Ames test indicated 210 ± 28 colonies/plate. A goat probiotic mixture (GPM): Lactobacillus reuteri DDL19, Lactobacillus alimentarius DDL48, Bifidobacterium bifidum DDBA and Enterococcus faecium DDE39 was orally administered as a treatment to diminish toxic substances. Ames test after a 25-days treatment with probiotics bacteria, sh
