The Marajó cheese is an artisanal product derived from buffalo milk produced in Marajó Island-PA. The objectives of this research were to characterize through physicochemical and microbiological the Marajó 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 Marajó 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.
