Catfish (Clarias gariepinus) is one of the fishery nutritious commodities that is quite popular in the community because it is cheap and easy to serve. It can be used as an alternative source to substitute protein from land source. Some of fish species, including catfish, contain higher and better protein than animal meat. Catfish are often grown in ponds in a sanitary manner because to the strong market demand. Due to the high bacteriological content of fishpond water, it is essential to identify the appropriate treatment for catfish. The aims of this study were to compare the impact of natural and artificial habitat and effect of different postharvest treatment on E. coli abundance. The study examined the bacteriological quality of 36 catfish from three distinct habitats and three different postharvest treatment methods. The result showed that there were no significant different (p=0.234) of the E. coli abundance among three different habitats. The number of MPN fecal coli varied based on the postharvest treatment of catfish which included washing, cleansing overnight in a water flow, and frying (p=0.001). Of the three post-harvest treatments, frying treatment resulted in significantly different MPN fecal coli. However, the frying treatment could not kill the E. coli completely. Hence the further study is needed to investigate the appropriate postharvest treatment which can control and reduce pathogenic bacteria spore in catfish.
