Cray fish (Astacus leptodactylus) is one of the foods used as a source of protein for both the high- and low- income earners, hence harbor pathogenic bacteria of public health significance. This study is aimed at evaluating the bacteriological quality of dried crayfish (Astacus leptodactylus) sold at Ogbete main market in Enugu metropolis, Nigeria. The two kinds of dry crayfish (Astacus leptodactylus) samples were screened bacteriologically using ten-fold dilution method. A total of sixty(60) dried crayfish samples (30 each for both sample) were collected from different sellers at Ogbete main market, Enugu. Two kinds of crayfish (Orini and Ishekeri) sold in the market were labelled as sample A and sample B. Staphylococcus aureus, Escherichia coli, Bacillus sp and Klebsiella sp were isolated. The mean bacterial load of these organisms ranged from 2.2x104 to 2.5x 104cfu/ml for both fish types. The prevalence rates are as follows: Staphylococcus aureus 30% and 26.67%, Escherichia coli 20% and 20%, Bacillus sp 13.33% and 16.67% and Klebsiellasp10% and 13.33% for both samples respectively. This result suggested that the samples were contaminated with bacteria which have been reported to be pathogenic to humans and animals, hence adequate hygiene must be observed during the collection, processing, transportation and sale of the edible food.
