Noroviruses (NoVs) are major foodborne pathogens that cause acute gastroenteritis. Oysters are significant carriers of this pathogen, and disease transmission from the consumption of NoVs-infected oysters occurs worldwide. The review discusses the mechanism of NoVs bioaccumulation in oysters, particularly the binding of histo-blood group antigen-like (HBGA-like) molecules to NoVs in oysters. The review explores the factors that influence NoVs bioaccumulation in oysters, including temperature, precipitation and water contamination. The review also discusses the detection methods of NoVs in live oysters and analyzes the inactivation effects of high hydrostatic pressure, irradiation treatment and plasma treatment on NoVs. These non-thermal processing treatments can remove NoVs efficiently while retaining the original flavor of oysters. However, further research is needed to reduce the cost of these technologies to achieve large-scale commercial applications. The review aims to provide novel insights to reduce the bioaccumulation of NoVs in oysters and serve as a reference for the development of new, rapid and effective methods for detecting and inactivating NoVs in live oysters.
诺如病毒（NoVs）是引起急性胃肠炎的主要食源性病原体。牡蛎是这种病原体的重要携带者，食用感染诺如病毒的牡蛎导致疾病传播在全球范围内发生。本综述讨论了诺如病毒在牡蛎中生物累积的机制，特别是组织血型抗原样（HBGA样）分子与牡蛎中诺如病毒的结合。本综述探讨了影响诺如病毒在牡蛎中生物累积的因素，包括温度、降水和水污染。本综述还讨论了活牡蛎中诺如病毒的检测方法，并分析了高静水压、辐照处理和等离子体处理对诺如病毒的灭活效果。这些非热加工处理可以有效去除诺如病毒，同时保留牡蛎的原味。然而，需要进一步研究以降低这些技术的成本，从而实现大规模商业应用。本综述旨在提供新的见解，以减少诺如病毒在牡蛎中的生物累积，并为开发检测和灭活活牡蛎中诺如病毒的新型、快速和有效方法提供参考。
