Abstract
The Marajo cheese is an artisanal product derived from buffalo milk produced in Marajo Island-PA. The objectives of this research were to characterize through physicochemical and microbiological the Marajo cheese cream type and the effect of the season. The pH, the percentage of fat in dry matter and content of sodium chloride were attributes that proximate composition showed significant difference at 5% probability by Tukey test between the two seasons. Statistical difference was not found in the percentage of titratable acidity, moisture, fat, ash, total solids extract, proteins and water activity. As for microbiological characteristics, in general, there was an improvement in the results in the dry season as to coliformes and Staphylococcus aureus. However, the result of Escherichia coli has proved to be better in the rainy season, with all samples meeting the standard of legislation. On the count of aerobic mesophilic there was no difference between the periods of the year. The pathogens Listeria monocytogenes and Salmonella sp. were not detected in the Marajo cheese, cream type, within the four seasons of the year. The variability occurred in pH, %NaCl, GES and, between seasons, demonstrates the need for greater control of production aimed at standardizing and maintaining the identity of the product. Regarding the microbiological, standards were established in accordance with the current legislation.

Summary
Foram coletadas 22 amostras de quei jos do Marajó tipo creme obtido de sete produtores de queijos, escolhidos de acor do com a disponibilidade dos produtos à venda, provenientes dos municípios de Soure e Salvaterra, na Ilha de Marajó (PA). As amostras foram coletadas nos pontos de venda, sendo 11 amostras na estação chuvosa, março a abril de 2012 e 11 amostras na estação seca, setembro a outubro de 2012. Denomina-se de estação chuvosa ou mais chuvosa os meses compreendidos de dezembro a maio, regionalmente chamado de inverno, com maiores índices pluviométricos entre fevereiro a abril. Essa estação apresenta os menores índices pluviométricos entre setembro e novembro. As amostras coletadas foram mantidas em suas embalagens originais de venda, armazenadas e transportadas em recipientes isotérmicos com gelo reciclável e mantidas sob refrigeração até o momento das análises físico-químicas e microbiológicas.
