The tools and equipment samples, during winter showed a Salmonella spp percentage that surpassed the allowed limits, according to International Commission on Microbiological Specifications for Food-ICMSF (1986), which are n = 5; c = 0; m = 0 y M = 0. The strains and water analyzed (cooling and truck) showed values of Salmonella spp inside boundaries. Conclusion. the influence of Salmonella spp in whole fish, fillets before cooling, fillets after cooling, injected and frozen variates between winter and spring stations, presented a bigger influence of microorganism in spring.
