Sazonalidade como fator interferente na composição físico-química e avaliação microbiológica de queijos coloniais / Seasonality as an interfering factor on the chemical composition and microbiological quality of colonial cheeses

The influence of seasonality on chemical composition of cheese produced during different seasons, was verified as well as their microbiological quality. A total of 32 samples of colonial cheeses produced in the southwestern Paraná were analyzed. Although the study could be thoroughly not completed, the chemical results showed significant variations (p <0.05) among the cheeses produced during the spring and summer seasons. The microbiological results indicated that 50%, 100% and 12.5% of the samples were contaminated with fecal coliforms, Staphylococcus coagulase positive and Salmonella spp., so at odds with the microbiological standards established by the legislation.
