Abstract
A total of 120 random samples of Nile tilapia, blue runner, bagrus, cat fish, mullet and striped red mullet (20 of each) were randomly collected from supermarkets and shops in Sharkia Governorate, Egypt.
6.1. Bacteriological evaluation of the examined fish samples
6.1.1. Enterococcus count:
The mean counts of Enterococcus on surfaces of the examined Nile tilapia, blue runner, bagrus, cat fish, mullet and striped red mullet samples was 3.3 ± 0.29, 3.6 ± 0.19, 4.7 ± 0.06, 3.4 ± 0.19, 3.7 ± 0.31 and 3.0 ± 0.19 log10 cfu ̸cm2, respectively; with minimum counts of 2.0, 2.6, 4.4, 2.7, 2.3 and 2.0 log10 cfu ̸cm2, respectively; and maximum counts of 4.5, 4.8, 4.9, 4.4, 5.2 and 3.9 log10 cfu ̸cm2, respectively. While the count of Enterococcus in muscles of the fish samples ranged from 2.0 to 4.3, 2.0 to 4.0, 2.5 to 5.0, 3.0 to 4.3, 3.0 to 5.5 and 3.0 to 4.2 log10 cfu ̸g, respectively with mean counts of 3.1 ± 0.25, 2.9 ± 0.21, 3.6 ± 0.22, 3.7 ± 0.16, 4.4 ± 0.30 and 3.8 ± 0.12 log10 cfu ̸g, respectively.
6.1.2. Psychrotrophic count:
