The goals of this study were to evaluate the physicochemical and microbiological quality of goatmilk produced in Distrito Federal, Brazil. The samples were collected as pool (n=40) and whole milksamples (n=10). The physicochemical means observed were: Fat (animals: 3.01% ± 0.679, wholemilk: 4.45% ± 1.223); nonfat solids (animals: 9.24% ± 0.651, whole milk: 9.2% ± 0.615); density(animals: 1.033g/mL ± 0.002, whole milk: 1.032g/mL ± 0.002); protein (animals: 3.5% ± 0.551, wholemilk: 3.67% ± 0.778); lactose (animals: 5.0% ± 0.035, whole milk: 4.94% ± 0.015); acidity (animals:18.47°D ± 0.552, whole milk: 18.5°D ± 0.5); pH (animals and whole milk: 6.9 ± 0.098); cryoscopic (animals:-0,560°H ± 0.010, whole milk -0.558°H ± 0.005). There were no positive samplesfor antibiotic residues. The mean scores microbiological counts were: aerobic mesophilic 1.2x103CFU/mL (animals), 7.6x103 CFU/mL (whole milk); total coliforms 1.0 CFU/mL (animals), 1.2x104CFU/mL (whole milk); Escherichia coli 2.0 CFU/mL (animals); psychrotrophics 1.0x104 CFU/mL(whole milk); acid lactic bacteria 4.7x102 CFU/mL (animals), 7.8x103 CFU/mL (whole milk); yeastand moulds, 1.0 CFU/mL (animals), 4.9x103 CFU/mL (whole milk); Staphylococcus aureus 2.1x102CFU/mL (animals), 2.8x102 CFU/mL (whole milk). Listeria monocytogenes and Salmonella spp.were not detected in any sample. The results indicate that the goat milk produced in Distrito Federaloffers quality and microbiological safety and may be an incentive for the further development of dairygoat.Keywords: goat farming; dairy activity; mesophilic aerobic bacteria; Salmonella.
