Occurrence of Listeria monocytogenes on the seafood contact surfaces of Tuticorin Coast of India

Abstract

was screened from different seafood contact surfaces in five sampling sites of fishing harbour, fish landing centers, seafood processing plants, fish market, and fish curing yards of Tuticorin Coast of India. 115 swab samples were collected and tested for the occurrence of by conventional and molecular methods. Overall, 5.22% of swab samples collected were positive for. The fishing harbour had high incidence (10.3%) of followed by fish landing centers (5.9%), and seafood processing plants (4.1%). Boat deck, fish transport tricycle were the two seafood contact surfaces in fishing harbour, which had the occurrence of. The swab samples from fish market and fish curing yards were negative for . All the isolated colonies of were confirmed by PCR assay targeting virulent gene. The DNA of all the isolates yielded a product of 174 bp on PCR amplification in comparison with Type culture (MTCC 1143). The results clearly indicated the occurrence of in seafood contact surfaces along the Tuticorin Coast of India.

Microbiological Factors of Food Quality for Risk Assessments in Europe: A Systematic Review

“…There are numerous works that studied contamination routes or ecology and physiology of Listeria monocytogenes in a great range of food products. Seafood and aquatic products, fresh produce, milk, meat, cheese are some food types already examined (Castro et al, 2018;Honjoh et al, 2018;Selvaganapathi et al, 2018).…”

Ecology of Listeria monocytogenes and Listeria species in India: the occurrence, resistance to biocides, genomic landscape and biocontrol

“…and L. monocytogenes were isolated from 24.34% and 8.69% of 115 seafood samples (Parihar A study conducted in Kerala's tropical seafood and fishery environment samples revealed L. innocua and L. monocytogenes (Das et al, 2013). Listeria monocytogenes could be detected from fishing harbours (10.30%), fish landing centres (5.90%), and seafood processing plants (4.10%) from Tuticorin Coast of India (Selvaganapathi et al, 2018). Listeria innocua (17.20%) and L. monocytogenes (2.70%) were isolated from the seafoods, RTE, and ready-to-cook (RTC) fish products from the retail fish markets of Kerala (Basha et al, 2019).…”

Insight into the genetic diversity, resistance, and virulence ofListeriafrom the marine environment: reveal the risk of hypervirulent isolates

“…It has been well documented that infection of L. monocytogenes is derived from the consumption of contaminated food, such as ready-to-eat meat, soft cheese, and unpasteurized milk. Pathogenic marine bacteria-contaminated seafood was a threat to human health, particularly in coastal cities (10,11). Water and soil are also sources of L. monocytogenes infection (12).…”
