Abstract
Aim: Most of the Indian
consumers hitherto invouge prefer to procure the fish in retail
markets despite of its poor unhygienic condition. Hence, multiyear
environmental study was carried out to scrutinize the hygienic status by
faecal indicator estimation in retail markets of Navi Mumbai region.
Methodology:
In
total, 159 marine fish were collected and analysed for estimation of aerobic
plate count and faecal indicator bacteria viz., E. coli, faecal
streptococci and sulphite reducing clostridia.
Results:
Aerobic
plate counts of all fish were within the limit; but the level of E. coli
was higher in retail fish i.e., 22.4%. The average level of E. coli,
faecal streptococci and sulphite reducing clostridia were 14, 31, 15 cfu g-1,
respectively. Higher ratio was observed between the faecal streptococci and E.
coli i.e., 1: 0.45. ???
Interpretation:
Fish
in retail markets harbour noteworthy number of faecal indicator bacteria
which indicates considerable number of faecal contamination and poor hygienic
status of the retail market. Repeated use of same water for washing fish may
be reason for the elevated level of contamination. So, cleaning of fish with
potable water may reduce contamination. In addition, these retail markets
need to be monitored by the controlling authority at regular intervals with
stringent control policy in order to provide safe seafood.
