The goal of paper was to evaluate the quality of fish commercialized in supermarkets and marketplace stalls in Cruz das Almas, Bahia. Sensorial, physicochemical and microbiological analysis were performed in 11 fish samples (three fresh fish samples, four frozen fish samples, and four dry salted fish samples). Supermarkets presented better hygiene conditions and facilities, and offered staff training. In the market stalls the facilities were in disagreement with food legislation. The sensorial analysis indicated tha 60% of the samples were in accordance with the concept of freshness. Hundred percent of the fresh and frozen fish samples were negative for sulphydric gas reaction, and humidity varied from 65.79 to 81.59%. Humidity in all the dry salted fish samples was higher than the maximum values allowed, and the chloride test was < 10%. Mesophilic bacteria counts varied from 4.66 × 106 to 6.84 × 106 CFU g-1 in fresh fish samples, and from 2.0 × 10 to 2.22 × 106 CFU g-1 in salted fish. The number of psychrotrophic bacteria in frozen fish varied from 1.08 × 103 to 1.76 × 105 CFU g-1. Coliforms at 45 ºC were observed in 100% of the samples and varied from < 3.0 to > 1.1 × 103 MPN g-1. Escherichia coli (08) was isolated only from fish samples collected in the marketplace stalls and was resistant to eritromicine 08 (100%), amicacyn 02 (25%), ampicillin, cephalotin and tetracycline 01 (12.5%). Multiresistance profile was observed in 62.5% of the isolates.
