Abstract Occurrence of faecal indicator bacteria (FIB) is
being reported regularly by various researchers. But there
is no information about the microbiological quality of the
water used in the retail fish markets. Hence to understand
the hygienic status of the water used in retail outlets, about
51 water samples were collected from the retail outlets of
Navi Mumbai region and microbiological parameters such
as aerobic plate count (APC), faecal indicator bacteria viz.,
Escherichia coli, faecal streptococci (FS) and sulphite
reducing clostridia (SRC) were enumerated. Antibiogram
was also carried out for 57 isolates against 20 antibiotics.
Results indicated that all water samples harboured higher
levels of APC, E. coli, FS and SRC with an average value
of 558, 41, 51 cfu/mL and 2.42/20 mL respectively. Ratio
between the FS and E. coli i.e., 1:1.25 indicates the multiplication
of E. coli in the water used in the retail market.
Higher level of resistance was observed for Augmentin and
Colistin. Four multi drug resistant (MDR) E. coli were
observed in the water samples. Checking of water in the
retail fish market is the most neglected area where high
level of contamination and MDR bacteria have been
detected. So, it was inferred that the repeated use of same
water without replacement is a major cause of higher levels
of FIB and MRD bacteria in the retail fish market water
samples that further leads to their transfer from water to
fish. Hence, running water facility should be used to clean
the fish.
