Abstract

Black Tiger Shrimp (Penaeus monodon) is one of the leading export commodities in Bangladesh. The industry, however, is frequently beset with quality deterioration and microbial diseases owing to various reasons. Here, we analyzed the sensory and nutritional qualities of shrimp, the total bacterial count, and molecular identification of pathogenic bacteria in samples collected from different supply chain actors (SCA), including the gher (farms), depots, wholesalers, retailers, and the processing industry in Khulna, Bangladesh. While the Sensory Quality Indices (SQI) of shrimps collected from farms, depots, and processing plants were found ‘excellent and highly acceptable’, the rating for wholesale and retail markets were ‘good and acceptable’. Nutritionally, higher protein (21.59%), lipid (1.47%), and ash (1.97%) contents were found in shrimps collected from farms than that of other SCAs. Heterotrophic bacterial count (cfu/g) differed in various SCAs: farms 3.75±0.31 (×106), depots 3.95±0.92 (×106), wholesale markets 5.03±0.35 (×106), retail markets 4.82±0.40 (×106), and the processing industry 3.78±0.25 (×106). The presence of Ralstonia spp and Pseudomonas spp, confirmed by 16S rDNA sequencing were found in different SCAs. Overall, the quality of shrimp appeared better in farms than that of other SCAs, indicating that a lack of proper hygiene, sanitation, and post-harvest handling practices could be the likely impediments for quality deterioration.

孟加拉国南部斑节对虾供应链细菌的质量评估和分子鉴定
斑节对虾是孟加拉国主要的出口商品之一。然而,由于各种原因,该行业经常受到质量恶化和微生物疾病的困扰。在这里,我们分析了从孟加拉国库尔纳的不同供应链参与者(SCA)收集的样本中虾的感官和营养品质、细菌总数和致病菌的分子鉴定,包括农场、仓库、批发商、零售商和加工业。虽然从农场、仓库和加工厂收集的虾的感官质量指数(SQI)被发现“优秀且高度可接受”,但批发和零售市场的评级为“良好且可接受”。从营养角度来看,从养殖场采集的虾的蛋白质(21.59%)、脂质(1.47%)和灰分(1.97%)含量高于其他SCAs。不同SCAs的异养细菌计数(cfu/g)不同:农场3.75±0.31(×106),仓库3.95±0.92(×106。通过16S rDNA测序证实,在不同的SCAs中发现了Ralstonia spp和Pseudomonas spp的存在。总的来说,养殖场的虾的质量似乎比其他SCAs的好,这表明缺乏适当的卫生、环境卫生和收获后处理做法可能是质量恶化的障碍。

期刊介绍: The journal (IAR) is an international journal that publishes original research articles, short communications, and review articles in a broad range of areas relevant to all aspects of aquatic sciences (freshwater and marine). The Journal specifically strives to increase the knowledge of most aspects of applied researches in both cultivated and wild aquatic animals in the world. The journal is fully sponsored, which means it is free of charge for authors. The journal operates a single-blind peer review process. The main research areas in aquatic sciences include: -Aquaculture- Ecology- Food science and technology- Molecular biology- Nutrition- Physiology- Water quality- Climate Change
