The informal milk is recognized as the product marketed without inspection. We evaluated the microbiological quality, nutritional ingredients and substances inhibiting bacterial growth in 100 informal samples from cows milk, marketed in the southwest region of the state of São Paulo, Brazil. It was found that 77% of Somatic Cell Count (SCC) and 86% of Total Bacterial Count (TBC) of the samples were at odds with the maximum values required by Instruction Rules 62 of the Ministry of Agriculture and Livestock Supply. It was identified to solids contents in disagreement (36%), protein (23%), fat (38%), nonfat dry extract (43%) and 73% urea nitrogen. In 59% of the samples was detected residues of the bacterial growth inhibitors. Were isolated 240 strains of micro-organisms with a prevalence of enterobacteria, streptococci, staphylococci and fungi. The informal milk is marketed in the region without the minimum hygienic conditions and present risks to public health, and represents serious socio-economic problem for the region. |
