“…The higher detection rate of GII over GI observed in our study could be related to higher GII prevalence in viral load excreted by the infected population. The present results are in agreement with other studies demonstrating a higher detection of NoV GII than NoV GI in India(Das et al, 2020), Italy(Fusco et al, 2019), Brazil(Cantelli et al, 2019;Reymão et al,…”

Mussels filter large amounts of water to extract nutrients; therefore, they can concentrate and accumulate in their tissues infectious agents, and vectors of enteric diseases. The aim of this study was to assess mussel contamination by Norovirus genogroups I and II in the Cherrat estuary to determine the public health risk linked to their consumption. Mussels (Mytilus galloprovincialis) were collected (n=52 samples; 12 mussels/sample) at four sites (S1 and S2 located on the right rocky bank / S3 and S4, located on the rocky left bank) in the Cherrat estuary (Casa-Settat region), Morocco, during 13 months, from March 2019 to March 2020. Norovirus was detected and quantified by real-time Reverse Transcription-Polymerase Chain Reaction (RT-PCR). Norovirus genogroups I and II were detected in 17.30% and 94.23% of mussel samples, respectively. Contamination by Norovirus (genogroups I and II) was not correlated with seasonal factors (month and rainfall), and Norovirus prevalence was comparable among the four sampling sites. Consumption of raw or undercooked mussels contaminated with Norovirus can cause gastroenteritis, which represents a potential risk to human health. The present study would be helpful to control and manage the potential risk to the public health of the Moroccan population due to the degradation of water quality continuously impacted by runoff, the urban wastewater treatment system malfunctions, and overflows from nearby sewage systems.

“…It is the major reason for nonbacterial gastroenteritis, causing >50% of foodborne gastroenteritis in the United States (Scallan et al., 2011). Molluscs (clams, oysters, and mussels) that are filter‐feeding, crustaceans (prawns and crabs), and finfish (anchovies and silver belly) were reported to carry norovirus (Das et al., 2020).…”

This review summarizes (1) the U.S. status quo for aquatic food animal production and marketing; (2) major food safety and quality issues/concerns for aquatic food animals in the United States, including fish misbranding, finfish/shellfish allergies, pathogens, toxins and harmful residues, microplastics, and genetically engineered salmon; and (3) various U.S. regulations, guidances, and detection methods for the surveillance of fishery products. Overall, fish misbranding is the biggest challenge in the United States due to the relatively low inspection rate. In addition, due to the regulatory differences among countries, illegal animal drugs and/or pesticide residues might also be identified in imported aquatic food animals. Future regulatory and research directions could focus on further strengthening international cooperation, enhancing aquatic food animal inspection, and developing reliable, sensitive, and highly efficient detection methods.

“…In comparison, NoV is often immune to certain commercial food storage practices and can withstand boiling, freezing, acidification, decreased water movement and changed packaging environment (Baert et al 2009). Shellfish, in particular moulds, clams and oysters, crabs, prawns, finfish, shirmps are usually implicated in seafoodborne norovirus outbreaks because of their feeding patterns as filter feeders and their capacity to absorb the virus from polluted water (Das et al, 2020;Woods et al, 2016). Throughout this filter feeding, bacteria and viruses may be stored and accumulated in their bodies due to land-based waste outflow or harvester runoff disposal (Bellou et al, 2013;Kohn et al, 1995;Le Guyader et al, 2006).…”

Non-enveloped human pathogenic viruses, highly stable in the environment, can be transmitted by different routes, such as contaminated food and water. The waterborne transmission of non-enveloped viruses to humans causes illnesses when individuals are exposed to contaminated water resources such as agricultural water, drainage, outdoor water, field or subsurface water and even drinking water. In addition to waterborne transmission, viral foodborne transmission may consist because of contagious seafood, through infected food handlers due to inadequate hygienic activities, aerosol containing viruses produced by infected people. Most hazardous non enveloped enteric viruses assocated with water and seafood cause a significant and emerging food safety and public health problem and threat. In this review, norovirus (NoVs), hepatitis E virus (HEV) and hepatitis A (HAV), human adenovirus, rotavirus A and sapovirus are evaluated as seafood associated human pathogenic non-envoleped viruses.
