| Abstract Mollusks are considered a nutritious source of food and their consumption has increased worldwide. However, their consumption, mainly of bivalves, has been considered responsible for numerous cases of foodborne diseases. This is related to their food intake, as they are filter-feeders and, consequently, bioaccumulate toxic compounds. High hydrostatic pressure (HHP) is recognized as an efficient technology to control pathogenic and deteriorating microorganisms, with low damage to the sensorial and nutritional properties of foodstuffs. This review addresses the use of HHP on bivalve mollusks, based on recent relevant studies in this field. |

| Created in 1986, the REPAMO network (Network of mollusc pathology), is a national zoosanitary surveillance network of shellfish health status along the French coasts. Its activities are in keeping with two European Directives, 91 /67/EEC and 95/70/EC and are a patt of the institutional tasks ofIfremer. The aims of the network are to prevent the introduction and spread of exotic pathogens and to survey the evolution of notifiable pathogens already present in France. The network focused on the survey of listed diseases (bonamiosis and marteiliosis of flat oyster) in two areas under agreement process (Banc de Granville and zone X). In 2004, no sample couId be analysed to these two areas because of the difficulty to obtain flat oysters (sparse oyster beds,... |

| Azaspiracids (AZAs) are a toxin group that originate from marine dinoflagellates of the genera Azadinium and Amphidoma. After accumulation of these toxins in edible marine organisms and their subsequent consumption, humans develop a gastrointestinal syndrome referred to as azaspiracid shellfish poisoning (AZP). This syndrome is very similar to diarrheic shellfish poisoning (DSP), with main symptoms appearing after a few hours from consumption and including diarrhea, vomiting, and stomach cramps. Due to extensive metabolism in shellfish, more than 30 analogues have been reported to date, and purified compounds for selected analogues have recently been made available for toxicological studies. Currently, only AZA1, AZA2, and AZA3 are regulated in Europe and... |

| 15% of the shellfish production in France comes from natural deposits and the other 85% from farming. Years 1980-1990 showed a slight decrease in the shellfish production then a resurgence from 1985 onwards, an increase in the oyster production and a strong decrease in mussel production at the beginning of the 1980's followed by a resurgence due to the increase of open sea activity. In France, the shellfish market represents 300,000 tons, divided between oysters (40%), mussels (30%) and scallops (15%). Importations of mussels and scallops in order to supply the domestic market are important. On the other hand, external trade flows are very low as far as oysters are concerned: France is the only important market for oysters in Europe. (unverified OCR) |

| Seafood could be a solution to meet global food demand that will double by 2050. Seafood includes a wide variety of edible marine organisms, except fish and mammals. These are molluscs, crustaceans, echinoderms and algae. Like any food, seafood can involve hazards transmitted to humans through food, which affect the health of the consumer. These hazards are both biological (viruses, bacteria, parasites) and chemical (toxins, allergens, chemicals, microplastics). The exposure of populations to these hazards through seafood consumption can be notably explained by their mode of production and the dietary habits. Firstly, the sanitary quality of products reflects the quality of the aquatic environment from which they are taken, which can be contaminated by... |

| Fishing and trade of living crustaceans are dynamic commercial sectors in France. 25 000 tons of local or imported crabs, lobsters , crawsfishes are yearly treated. Based upon a literature review and fishmongers interviews, this study describes the current pratices and problems associated to live crabs and lobsters storage. Supply conditions of live crustaceans, marketing networks, and biological, ecological and physiological characteristics of crustaceans were discussed. Morever, storage facilities, their operating rules and factors affecting the survival rate under storage and transportation conditions were reviewed. |

| Coastal benthic ecosystems may be impacted by numerous human activities, including aquaculture, which continues to expand rapidly. Indeed, today aquaculture worldwide provides more biomass for human consumption than do wild fisheries. This rapid development raises questions about the interactions the practice has with the surrounding environment. In order to design strategies of sustainable ecosystem exploitation and marine spatial planning, a better understanding of coastal ecosystem functioning is needed so that tools to quantify impacts of human activities, including aquaculture, may be developed. To achieve this goal, some possible directions proposed are integrated studies leading to new concepts, model development based on these concepts and... |

| Human enteric viruses discharged in raw sewage are hightly resistant and may be detected in surface waters, coastal areas and shellfish. Whereas noroviruses, responsible for relatively benign acute gastroentritis, are the most common agents implicated in shellfish borne outbreaks, other human viruses which cause severe human diseases, such as hepatitis A virus, may also be transmitted. Environmental studies have demonstrated that virus concentrations detected in shellfish are higher than in surrounding waters. This concentration may explain the high prevalence of noroviruses detected in various shellfish species collected in different countries. If many questions remain regarding viral contamination of shellfish, the most important seems to be the... |

| Shellfish contamination by human noroviruses (HuNoVs) is a serious health and economic problem. Recently an ISO procedure based on RT-qPCR for the quantitative detection of HuNoVs in shellfish has been issued, but these procedures cannot discriminate between inactivated and potentially infectious viruses. The aim of the present study was to optimize a pretreatment using PMAxx to better discriminate between intact and heat-treated HuNoVs in shellfish and sewage. To this end, the optimal conditions (30 min incubation with 100 μM of PMAxx and 0.5% of Triton, and double photoactivation) were applied to mussels, oysters and cockles artificially inoculated with thermally-inactivated (99 °C for 5 min) HuNoV GI and GII. This pretreatment reduced the signal of... |

| Certain species of the marine diatom genus Pseudo‐nitzschia are responsible for the production of the domoic acid (DA), a neurotoxin that can bioaccumulate in the food chain and cause amnesic shellfish poisoning (ASP) in animals and humans. This study extends our knowledge by reporting on the first observation of the potentially toxic species Pseudo‐nitzschia simulans from this region. One clonal strain of P. simulans was isolated from the East Australian Current and characterized using light and transmission electron microscopy, and phylogenetic analyses based on regions of the internal transcribed spacer (ITS) and the D1–D3 region of the large subunit (LSU) of the nuclear‐encoded ribosomal deoxyribonucleic acid (rDNA), as well as examined for DA... |

| This study assessed the apoptotic process occurring in the hemocytes of the Pacific oyster, Crassostrea gigas, exposed to Alexandrium catenella, a paralytic shellfish toxins (PSTs) producer. Oysters were experimentally exposed during 48 h to the toxic algae. PSTs accumulation, the expression of 12 key apoptotic-related genes, as well as the variation of the number of hemocytes in apoptosis was measured at time intervals during the experiment. Results show a significant increase of the number of hemocytes in apoptosis after 29 h of exposure. Two pro-apoptotic genes (Bax and Bax-like) implicated in the mitochondrial pathway were significantly upregulated at 21 h followed by the overexpression of two caspase executor genes (caspase-3 and caspase-7) at 29 h,... |

| Shellfish consumption is clearly associated with the transmission of enteric viruses. The channel of transmission of enteric viruses to human beings could be decreased particularly if the systems of depuration of shellfish were optimized, standardized and if their viral efficiency was controlled. The purpose of this work was to study the contamination of oysters and to assess the efficiency of several depuration processes. Our study have demonstrated that in some cases, 50% of oysters samples contain enteric viruses or H.A.V. antigen and the quantities of viruses range from 17 to 246 FF for the rotaviruses and from 124 to 200 for the enteroviruses per 100 g of tissue. According to our results, the exclusive use of a bacteriological criterium to determine... |

| Pinnatoxins (PnTXs) are a group of emerging marine biotoxins produced by the benthic dinoflagellate Vulcanodinium rugosum, currently not regulated in Europe or in any other country in the world. In France, PnTXs were detected for the first time in 2011, in mussels from the Ingril lagoon (South of France, Mediterranean coast). Since then, analyses carried out in mussels from this lagoon have shown high concentrations of PnTXs for several months each year. PnTXs have also been detected, to a lesser extent, in mussels from other Mediterranean lagoons and on the Atlantic and Corsican coasts. In the French data, the main analog is PnTX G (low levels of PnTX A are also present in some samples). No cases of PnTXs poisoning in humans have been reported so far in... |

| Toxin monitoring is carried out along the coasts of France by a national network, REPHY, which is the National Monitoring Network for Phytoplankton and Phycotoxins. Sampling strategy differs according to the type of zone coastal or offshore and to the family of toxins. For PSP and ASP toxins, monitoring is based on the detection of toxic phytoplankton species. For lipophilic toxins, a systematic analysis of toxins is performed in risk areas during high risk periods. Experimental monitoring for palytoxins has also been conducted along the Mediterranean coast since 2007. The total number of toxin analyses is in the order of 2500 to 3000 per year. The detailed results for each family of toxins showed that the most frequent toxic events for the period from... |

| Infectious diseases linked to the consumption of raw shellfish have long been identified. Over the past century, various strategies have been set up in shellfish growing areas throughout the world to guarantee the sanitary quality of shellfish and to protect consumers. However despite sanitary improvements, human enteric viruses - especially Hepatitis A virus and norovirus– have been found to be associated with shellfish outbreaks. A recent example demonstrated the impact of storm events. Following heavy rain and sewage overflow, shellfish beds were contaminated and the shellfish from them were marketed after depuration. However, since viruses persist longer than fecal contamination indicator bacteria, several clusters of gastroenteritis cases were... |
