Detection of pathogenic bacteria in retailed shrimp from Bangladesh

Abstract The presence of pathogenic bacteria is a problem that might be present in farmed shrimp due to exposure in the environment or post‐harvest handling. Retail farmed shrimp in Bangladesh ( Penaeus monodon and Macrobrachium rosenbergii ) were tested for common pathogenic bacteria namely Salmonella, L. monocytogenes, Vibrio spp., and E. coli . None of these bacteria were found and instead Enterobacter cloacae, Escherichia fergusonii, Proteus penneri, Klebsiella aerogenes, Enterococcus faecalis, Serratia marcescens, Citrobacter freundii , and Aeromonas dhakensis were detected. Pathogenic bacteria found in Bangladeshi shrimp may be due to the farm environment, poor handling during harvest or post‐harvest, or unhygienic market conditions. The results indicate that retail shrimp from Bangladesh have food safety concerns. Proper laws and policies need to be enforced and implemented to ensure food safety related to fish and shrimp.
