Curing of fish is a traditional and economical method of fish preservation preferred in rural areas. A considerable quantity of cured fish marketed in Cochin is coming from local small scale curing units. But the quality of these cured products can be deteriorated biochemically and microbiologically due to the usage of poor quality raw material, inadequate curing procedures, unhygienic handling and improper storage conditions etc. In this background, a study was carried out to evaluate the biochemical and microbial quality of cured fish produced in small scale curing units of Cochin, Kerala. A total of forty-four number of cured fish samples coming under seventeen varieties were collected and evaluated. The cured fish included directly sundried products without salting, salt dried products and wet cured products. Biochemical parameters such as water activity, moisture, ash, sand, salt, TVBN and TMA and microbiological parameters such as aerobic plate count, total fungal count and coagulase positive Staphylococcus aureus count were assessed. Water activity of the samples ranged from 0.48 to 0.82 and 6.81 per cent of samples exceeded the value of 0.78. Moisture content of samples was varying and 22.73 per cent of samples contained moisture content above 40 per cent. 26.67 per cent of salt cured samples contained salt content less than 12 per cent. Sand content above 1 per cent was observed in 40.9 per cent of samples with highest in case of Mackerel. TVBN content ranged from 84 and 273 mg per cent and TMA from 28 and 210 mg per cent. Aerobic plate count of cured fish samples were ranging from 3.04 to 7.02 log CFU per gram, and in 47.7 per cent of samples which was above 5 log CFU per gram. Presence of coagulase positive Staphylococci was detected in three of the samples evaluated under study. Total fungal count in 68.2 per cent of cured fish samples was above 2 log CFU per gram.
