Enumeration of E. coli, Coliform and Aerobic Bacteria in Marine Fish in Port Sudan, Red Sea State, Sudan

Abstract

This study was carried out to detect the total bacterial count, coliform count and E. coli count through the production chain of marine fish (fish market, scaling, restaurant before cooking, restaurant after cooking and cooking and cooling for 24 h) in Port Sudan, Red Sea State, during the period from September to December 2018. A total of 50 fish samples were randomly selected from marine fish chain. Samples were subjected for bacteriological examination. The study showed that the mean count of E. coli in the five stages of the fish chain was 2.57×10 2 +0 .6 cfu, the mean coliform count was 2.01 ×10 3 + 0 .7 cfu/ g and the mean Aerobic Plate Count (APC) was found to be 3.6×10 6 + 0.09 cfu/ g. E. coli showed higher mean count (7.58×10 2) cfu/ g in the scaling stage. The
