Abstract
In India, fish consumers prefer three types of retail markets viz., local dry fish market,
local fresh fish market and supermarket wherein no stringent food safety measures are
followed and monitored. Hence, the present study was planned to analyze food safety
parameters for different outlets by collecting equal numbers of fish samples from all three
markets of Navi Mumbai region. Proximate composition, biochemical and microbiological
parameters were evaluated. Antibiogram for the isolated Staphylococcus aureus and
Escherichia coli from these fishes was studied. In dry fish market, most of the fish had
higher total volatile basic nitrogen (TVB-N) and formaldehyde than permissible level. In
present evaluation, formaldehyde content of fishes from different markets exhibited a
higher percentage (1.03-1.93 mg%) than the recommended value. Local retail fresh fish
market samples had higher levels of Aerobic Plate Count (APC), E. coli and S. aureus.
One sample from dried fish market exceeded the permissible limit of APC (2,36,000
cfu/g). Supermarket samples contained all the microbial and biochemical levels within the
limit but exhibited higher formaldehyde content. Multiple drug resistant bacteria also
existed in both local and supermarket samples. Monitoring authorities of India need to
monitor the quality of fish in different markets at regular interval and strict action may be
taken for seafood safety.
