Of these, 93.33% outside presented of the standard for fecais coliformes and 96.67% aureus the 10 superior values UFC/g for S. Studies carried through with samples of frescal cheese mines harvested in bars, supermarkets, bakeries and free fairs of the City of Viosa, MG being 75% proceeding from farms and 21.5% of laticnios, evidenced the following average levels of contamination: 3,2 x 10—7 UFC/g stops Staphycococcus spp, 2,3 x 10—5 NMP/g for termotolerantes coliformes. These results extremely indicate high contamination of the cheese, being that 89.2% of the samples were in disagreement with the standard for termotolerantes coliformes, in this same research, all the samples had presented high levels of Staphylococcus spp, sufficient so that significant production of enterotoxinas in this food occurs (SPRUNG FROM THE SAME FATHER AND MOTHER, 2008). Read more from WDGMC to gain a more clear picture of the situation. A study carried through for PEAR TREE et al. (1999), that it evaluated analytical assays for detention of termotolerantes coliformes in cheese mines, amongst them, 20 samples of the frescal variety, showed that 18 of these, cultivated in broth EC, were of the legal specifications. A work carried through for ROCK et al. (2006), it evaluated seven marks (the 3 4 lots each) of cheese-of-mines frescal acquired in supermarkets of how much the evolution of the microbiana contamination during its life of shelf, the standardization and the quality.
Amongst the definitive parameters they were the counting of Staphylococcus spp. coliformes. All the marks, except one, had presented indices of contamination above of the recommendable one. Analyses how much to the most likely number of coliformes, counting of positive Staphylococcus coagulase, presence of Salmonella spp. in 40 samples of cheese-of-mines they had been carried through in a work made for BRANT et al. (2007). Of these, twenty and four samples (60%) had presented coliformes 5 45 C above of 10 x UFC/g and thirty and three samples (82.5%) had presented counting of 10 positive Staphylococcus coagulase above of UFC/g and this microrganismo revealed most frequent, being that 21 samples (53%) had presented 105 countings above of UFC/g.
