| 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... |

| Chlordecone is a very persistent insecticide used in banana plantations of the French West Indies between 1972 and 1993. Chlordecone residues were found in inland water, in agricultural and freshwater products, and in marine organisms. This pollution has become of great concern in 2007. Therefore, a governmental action Plan was launched to better assess the pollution and to improve the consumer’s protection. Within this plan, 1048 samples from 69 different species of marine fishes and crustaceans were collected all around both the Guadeloupe and the Martinique Islands and analyzed. The results confirm the presence of chlordecone in marine organisms, with highly variable concentrations (from the detection limit to 1000 μg.kg-1). In 17.9 % of the samples,... |

| The occurrence of new phytoplankton species in a coastal area may be explained by the import of shellfish containing whole live algal cells in their digestive tracts. Indeed, shellfish containing toxic algal cells can induce both primary contaminations in safe areas ( initially free from toxic microalgae), and secondary contaminations of other shellfish growing in the same area via the faeces of the imported animals. To mitigate this problem, shellfish need to be placed in a separate holding tank and their intestinal content purged. For a deeper understanding of the risks associated with transferring contaminated shellfish, oysters ( Crassostrea gigas) and mussels ( Mytilus edulis) were purposely fed either Alexandrium minutum or A. catenella (... |

| An initial surveillance system of Ostreopsis ovata was set Lip along the Mediterranean coast in the summer of 2007. To Strengthen and adapt this system, we reviewed the information available for a health risk assessment of this monocellular species of algae that produces palytoxin and is increasingly observed in the Mediterranean Sea. Since 2002, this species has been reported to be responsible for many human cases of irritation, Cough, fever and respiratory problems in Europe. It is not Currently possible to determine if palytoxin causes these health effects, which follow aerosol inhalation. Ingestion of contaminated seafood may lead to very serious poisoning, but no such case has yet been described in Europe. A "dose-response' relation cannot be... |

| Collisions between ships and whales raise environmental, safety, and economic concerns. The management of whale-ship collisions, however, lacks a holistic approach, unlike the management of other types of wildlife-vehicle collisions, which have been more standardized for several years now. In particular, safety and economic factors are routinely omitted in the assessment of proposed mitigation solutions to ship strikes, possibly leading to under-compliance and a lack of acceptance from the stakeholders. In this study, we estimate the probability of ship damage due to a whale-ship collision. While the probability of damage is low, the costs could be important, suggesting that property damages are significant enough to be taken into consideration when... |

| In a recent report by risk assessment experts on the identification of food safety priorities using the Delphi technique, foodborne viruses were recognized among the top rated food safety priorities and have become a greater concern to the food industry over the past few years. Food safety experts agreed that control measures for viruses throughout the food chain are required. However, much still needs to be understood with regard to the effectiveness of these controls and how to properly validate their performance, whether it is personal hygiene of food handlers or the effects of processing of at risk foods or the interpretation and action required on positive virus test result. This manuscript provides a description of foodborne viruses and their... |

| This article presents the results of multidisciplinary research (geochemistry, sociology) into the increasing concentrations of silver (Ag and nanoAg) in the environment and their potential impact on aquatic environments. We investigate simultaneously the risk of contamination of these environments by silver and the process of the social and political construction of this risk by water managers, health authorities, agencies and committees responsible for expert evaluations, environmental associations, and potential users of silver or nano-silver. Four updated models of risk construction allow us to understand the logic of arguments mobilized at this stage of the emerging risk. This interdisciplinary cooperation opens up possibilities for dealing with some... |

| Uptake of waterborne Cd, Co, Mn and Zn was determined in laboratory experiments using radiotracer techniques (Cd-109, Co-57, Mn-54 and Zn-65). Labelled Zn was mainly accumulated in the digestive gland (65%) and Co in kidneys (81%); Cd and Mn were similarly distributed in digestive gland and gills. In a complementary field study, Ag, As, Cd, Co, Cr, Cu, Fe, Mn, Ni, and Zn were analysed in scallops collected at two stations showing different contamination levels. Digestive gland and kidneys displayed the highest concentrations. Ag, As, Cd, and Fe differed in soft tissues from the two stations, suggesting that Comptopallium radula could be a valuable local biomonitor species for these elements. Low Mn and Zn concentrations found in kidneys suggest that their... |

| Since the first case of bovine spongiform encephalopathy (BSE) was encountered in Japan in 2001, the country quickly responded with a change from passive to active surveillance. The response has not been a smooth one, though, and news media have contributed to opening the public’s eyes to inadequate behavior from government sources responsible for monitoring and protecting the health of consumers. The resultant information“gap” has served to augment the typical Japanese perceptions of risk assessment, as assessed in surveys from 2003 to 2005. Such false beliefs have caused consumers to call for 100% testing of animals for BSE despite accepted scientific standards which do not support such comprehensive and costly surveillance. Instead, testing agencies... |

| Before planning the large-scale use of nonpathogenic strains of Fusarium oxysporum as biocontrol agents of Fusarium wilt, their behaviour and potential impact on soil ecosystems should be carefully studied as part of risk assessment. The aim of this work was to evaluate the effects of antagonistic F. oxysporum strains, genetically manipulated (T26/6) or not (233/1), on soil microbial biomass and activity. The effects were evaluated, in North-western Italy, in two soils from different sites at Albenga, one natural and the other previously solarized, and in a third soil obtained from a 10-year-old poplar stand (Popolus sp.), near Carignano. There were no detectable effects on ATP, fluorescein diacetate hydrolysis, and biomass P that could be attributed to... |

| This paper seeks to inform the current "regulatory reform" effort in the U.S. by describing how information from risk assessments and cost-benefit analyses is used by decision makers in six other industrialized countries. In Japan, Germany, the United Kingdom, Netherlands, Canada and the European Union decision makers deal with uncertainties associated with risk assessments differently than in the U.S. They are less likely to employ "default assumptions" to bridge uncertainties and instead tailor risk evaluations to the chemical in question. Furthermore, while U.S. agencies are sometimes required to pair information from risk assessments with data from cost-benefit analyses in order to estimate how much it costs to stem or avert environmental and health... |

| Salmonellosis, a common human intestinal disorder primarily caused by contaminated meats and poultry, attacks an estimated two million Americans annually. Using a cost of illness approach, the medical costs and productivity losses alone were estimated to cost around one billion dollars in 1987. If pain and suffering, lost leisure time, and chronic disease costs could be quantified, the estimate would increase significantly. Other procedures for calculating the value of life could either raise or lower the estimated economic benefits of reducing human salmonellosis. Incorporating losses to farmers, whose animals have reduced feed efficiency, reduced weight gain, or deaths because of chronic salmonellosis, would also increase the estimates. Also excluded... |

| This paper deals with the ex-ante analysis of the effects of farm subsidies on farm behaviour. Beside that the risk factor is implemented in the farm model to reflect and quantify potential (negative) impact on farm results. A farm-level optimization model is used to assess the effects of different kind of policies and risk on production structure, income indicators and land use management. It appeared that a reasonable level of risk (via income variation) have impact, but not significant. If liberalisation would have happened (zero direct and disadvantageous payments) production would homogenised, 30% of land would remained abandoned, production and income would clearly decline. Other scenario points out that environmental objectives (here through more... |

| Current policies designed to improve food safety rely on regulation and market incentives. However, the mix of both private and public incentives to improve food safety and the dynamics of industry response to regulation make analysis of the costs of food safety complex. The paper provides an overview of costs of food safety regulation and control in recent literature for both pesticide and microbial controls and draws lessons for identifying cost-effective food safety approaches. Four lessons emerge concerning industry compliance costs. First, the distribution of costs is likely to be more important than market price effects. Second, regulation has an impact on long-run incentives to invest in new technologies or inputs and therefore may bias the nature... |

| The United States regulates deliberate species introduction by blacklists: any species not blacklisted may be imported. Half of invasive introduced species were deliberately introduced, yet most were not blacklisted, so this system is not working. White lists are also needed: no species can be deliberately introduced unless experts place it on a white list. The United States has not closed pathways for inadvertent introductions, which are regulated by international treaties. Risk assessments for introduced species have mostly targeted species as potential vectors for pathogens rather than as potentially invasive themselves. Although multilateral treaties mandate quantitative risk assessments for exclusions of species or goods that may carry them,... |
