Estudio de la calidad microbiológica de los pescados frescos de exportación

Abstract:

The present work describes the study of the quality microbiological of the fresh fish of export, carried out between February of the 2000 and February of the 2001, in patterns from fishing companies been located in Manabí and Guayas. 246 patterns of 5 species: 35 of Skipjack; 43 of Yellowfin, 50 of Bigeye, 56 of Fish Sword and 62 patterns of Picudo. The patterns were analyzed following the methodologies of: The International Commission of Microbiológicas Specifications for Foods (ICMSF); the norms of the Manual Analytic Bacteriológico (BAM) of the FDA; and the techniques described in the Association of Official Analytical Chemist (AOAC). It was checked that they values gotten of the Total Contaje of Aerobios (TVC) at 25°C, was understood within the international accepted ranges, determining it that 45 that is to say the 18% they of the patterns presented security between 10 (1 x 101) and 1000 (1 x 103) Formadoras Units of Colonies for gram (UFC/g); the 42% (103) it reached figures between 1001 (1.1x103) and 10000 (1x104) UFC/ g, and the 40% (98) it got contajes of bacterias between 10001 (1,1x104) and 100000 (1x105). The outputs for the determination of fecal coliform were, for the 48% you of the patterns value of minor at 3 (< 3) More Probable Number for gram (NMP/g); the 29% of the patterns presented security between 3 and 9.2 NMP/ g; the 18% the values were between 35 and 9.3 NMP g and the 5% security between 36 and 64 NMP/ g. Absence in the 100% was determined you of the patterns analyzed for them taste bacterias like: Vibrio cholerae, Estafilococos aureus, Escherichia coli and Salmonella, that they are the most common causes of the ETAS.
