RESUMOCom o objetivo de avaliar a qualidade de camarão salgado seco (aviú) e de farinha de peixe (piracuí), foram obtidas 27 amostras, analisadas seguindo metodologias oficiais. Os resultados físico-químicos foram, em média, de 24,0 % e 18,76 % de umidade, 22,68 % e 12,91 % de cinzas, 15,67 % e 8,20 % de cloretos, 0,61 e 0,57 de atividade de água, respectivamente, para aviú e piracuí; ademais, 30,77 % de amostras de aviú e 7,14 % de piracuí excederam o limite máximo permitido para cinzas. O ranço oxidativo foi detectado em 74,07 % das amostras pesquisadas. Das 21 amostras analisadas para contagem de fungos, 100 % apresentaram contaminação. As contagens de Staphylococcus coagulase positiva não atenderam aos respectivos valores máximos regulamentados, em 61,54 % das amostras de aviú e em 78,87 % das de piracuí. Enterococcus spp. foi detectado em 69,23 % e 64,28 %, respectivamente, das de aviú e piracuí. Houve ocorrência de Salmonella spp. em cinco amostras. Estes alimentos comercializados em Belém apresentaram condições higiênico-sanitárias insatisfatórias e inexata qualidade.

ABSTACTTwenty-seven samples of dried-salted shrimp ("aviú") and "piracuí" type fish meal were tested for evaluating the physical-chemical and microbiology qualities. The mean values of moisture, ash, salt contents and water activity (Wa) were 24.0 % and 18.76 %, 22.68 % and 12.91 %, 15.67 % and 8,20 %, 0,61 and 0,57 for aviú and piracuí samples, respectively. The ash values were above the maximum limit permitted by legislation in 30.77 % and 7.14 % of "aviú" and "piracuí" samples, respectively. Oxidative rancidity was showed in 74.07 % of samples. Yeast and mold were detected in all analyzed samples (n = 21). Coagulase-positive Staphylococcus counts were above the maximum limit permitted by legislation in 61.54 % and 78.87 % of "aviú" and "piracuí" samples, respectively. Enterococcus spp. was detected in 69.23 % and 64.28 % of "aviú" and "piracuí" samples, respectively. Salmonella spp. was isolated from five samples. The dried-salted shrimp ("aviú") and the "piracuí" type fish meal sold in Belém showed unsatisfactory hygienic-sanitary quality, and microbiologic characteristics of a potential risk to public health.

The article describes the first occurrence of hepatic coccidiosis in catfish of the species Brachyplatystoma vaillantii, captured in the coastal region of the Vigia city , state of Pará, Brazil, caused by species of the genus Calyptospora, family Calyptosporidae. Thirty specimens of piramutabas were examined where 60% were infected with liver location, featuring numerous mature and immature oocysts, grouped or isolated, with four sporocysts in pyriform shape. They were described on their morphology and dimensions of the oocysts and sporocysts, obtained from light microscopy and differential interference contrast.
