Isolation And Identification Of Pathogenic Bacteria In Edible Marine Fish, Rastrelliger Kanagurta And Scomberomorus Guttatus (Scombridae) Landing At Visakhapatnam Fishing Harbour, Andhra Pradesh

Abstract

The study reports on the isolation and identification of certain pathogenic bacteria in commercially and
nutritionally important edible marine fish, Rastrelliger kanagurta and Scomberomorus guttatus. In R. kanagurta,
Escherichia coli, Staphylococcus aureus and Vibrio cholera were found while in S. guttatus, only Salmonella sp. was
found. All these bacteria are pathogenic and cause sickness indicating that these fish are contaminated with
microbes and need to be properly processed and cooked prior to consumption by humans. Further, it is
recommended that the consumers need to be educated regarding the health issues that arise from the
consumption of this fish contaminated with pathogenic bacteria.
