Fish are the source of high-quality protein and are preferable due to its exceptional richness in calcium, phosphorus and vitamins. Photobacterium damselae is a potential pathogen of marine fish and an opportunistic pathogen in humans which causes pasteurellosis. A study for the screening of Photobacterium sp. in the marine fish landings of Pulicat Lake, Tamil Nadu, India was undertaken between August 2018 and February 2019. About 113 samples of fishes belonging to various species viz., Ablenneshians, Rastrelliger kannagarta, Hemiramphus, Thunnus sp., Nemipterus bipunctatus, Leognathus sp., Scombroid sp., Saurida thumbil, Triacanthus biaculatus and Pomadasys sp. were used for the study. Photobacterium sp. has been isolated in 26 fish samples which include Rastrelliger kannagarta (13/16), Leognathus sp. (4/11) and Saurida thumbil (9/11). Pathogenic Photobacterium sp. could pose threat to the health of consumers through the ingestion of contaminated, improperly cooked seafood or may gain entry to the human body during handling of contaminated fish through the cuts or abrasions or by swimming and other recreational activities in the contaminated water bodies.
