Methicillin-Resistant Staphylococcus aureus in Seafood: Prevalence, Laboratory Detection, Clonal Nature, and Control in Seafood Chain.

Methicillin-resistant Staphylococcus aureus (MRSA), a versatile pathogen bearing multiple virulence determinants, is increasingly being detected in various food-producing animals, including fish. In addition, it is a potential food poisoning agent. MRSA is not an inherent microbiota of fish; its presence is attributed to pre- or postharvest contamination through fish handlers, water, ice, and processing equipment.

Effects of microwave vacuum drying and conventional drying methods on the physicochemical and microstructural properties of squid shreds.

Background: Microwave vacuum drying is an innovative technology for drying fruits and vegetables. However, this technology has not been well explored for drying seafood. In the present study, the effects of microwave vacuum drying (MVD), hot air drying (HAD) and sun drying (SD) on the proximate composition, texture, rehydration, color and microstructure of squid shreds were investigated.

Assessment of polyaromatic hydrocarbons and pesticide residues in domestic and imported pangasius (Pangasianodon hypophthalmus) fish in India.

Background: The pangasius catfish (Pangasianodon hypophthalmus) is a ubiquitous item of seafood in global markets. However, pesticide residues in aquaculture fish, arising from agricultural run-off and/or direct application during pond preparation, pest control and harvest, are a potential food safety concern. This study assessed the level of chemical hazard in domestic and imported pangasius fish in India.

Detection of ctx gene positive non-O1/non-O139 V. cholerae in shrimp aquaculture environments.

Water and post-larvae samples from black tiger (Penaeus monodon) shrimp hatcheries; pond water, pond sediment and shrimp from aquaculture farms were screened for the presence of V. cholerae. A V.

Genetic heterogeneity of non-O1 and non-O139 Vibrio cholerae isolates from shrimp aquaculture system: a comparison of RS-, REP- and ERIC-PCR fingerprinting approaches.

Aims: The genetic diversity of Vibrio cholerae isolated from black tiger shrimp (Penaeus monodon) aquaculture farms was determined using three PCR typing methods based on enterobacterial repetitive intergenic consensus (ERIC) sequences, ribosomal gene spacer (RS) sequence and repetitive extragenic palindromic (REP) sequences.

Methods And Results: Non-O1 and non-O139 V. cholerae isolates were obtained from shrimp pond water, pond sediment, shrimp head and shrimp muscle.
