The aim of this study was to evaluate the microbiological quality of UHT (Ultra High Tempereture) goat milk. Microbiological analysis was used for detection and isolation of the genera Staphylococcus sp., Bacillus sp. and Clostridium sp. in one hundred of samples from different regions of the country. All genera mentioned, excepting Clostridium sp., have been found in the analyzed samples. The mesophilic bacteria were positive in 21% of samples. Bacillus sp. and Staphylococcus sp. were isolated in 32% and 36% of the analysed samples respectivelly . The mean of Staphylococcus sp. were of 5,21x10¹CFU mL-1. Meanwhile for Bacillus sp. were 4,87x10¹CFU mL-1. The results suggest that thermal process UHT used in these samples was not enough to destroy the microorganisms. This information is important to warn Public Health authorities about the potential risks of these food-poisoning microorganisms. Effective improvement of programs is necessary to control and prevent these agents therefore improving milk quality.
