Avaliação da qualidade sanitária dos peixes Pomadasys maculatum e Otolithes ruber no mercado da Massanica, distrito de Mocuba, província da Zambézia

Abstract

Among several known foodstuffs is fish, which from a nutritional point of view stands out because it presents proteins of high biological and energetic value, excellent quality lipids and satisfactory amounts of water-soluble vitamins (B complex), liposoluble (A and D), important minerals such as Mg, Ca, Fe, P, Zn and Cu, which make fish meat a food with high digestibility and absorption capacity (Tete, 2012). The conditions of hygiene and sanity of the stands are important in the commercialization of food. The objective of this study was to evaluate the sanitary quality of Pomadasys maculatum and Otolithes ruber fish in the Massanica market, Mocuba district, Zambézia province. The research was carried out through site visits, questionnaire to merchants, registration through photographs of the sanitary conditions of commercialized fish, sensorial and microbiological analyzes. The results on trade indicate that all traders of fresh fish do not follow the standards of good practice for trading fish. In all samples, the following microorganisms were found: total coliforms, thermotolerant coliforms, Escherichia coli, with excision of coagulase positive Staphylococci, Vibrio Cholerae and salmonella in the samples of both Pomadasys maculatum and Otolithes ruber. For Escherichia coli, both samples <3NPM / g, 43 NPM / g (Pomadasys maculatum) and 75 NPM / g (Otholithes ruber) were found.
