Funding Information: This project received funding from the COST Action CA18218 European Burden of Disease Network, supporting the first author with a Short-Term Scientific Mission to the National Food Institute, Technical University of Denmark, with the aim of improving knowledge and applying the appropriate methodology on burden of disease on this project.The authors would like to thank the researchers from the Research Group for Risk Benefit from the National Food Institute, Technical University of Denmark for raising questions to improve the robustness of the research project, as well as the COST Action CA18218 European Burden of Disease Network for funding and supporting the project, and to the researchers Carla Martins from NOVA National School of Public Health and Ricardo Assunção from Egas Moniz Cooperativa de Ensino Superior for contributing to the initial brainstorming on the disease pathology.

In 2025, the occupational exposure limit is set to change to 5 μg/m3. Current exposure limits are higher, with 10 μg/m3 as a general limit and 25 μg/m3 for the welding industry. We aimed to assess the current burden of lung cancer caused by occupational exposure to Cr(VI) and to evaluate the impact of the recently established EU regulation by analysing different occupational exposure limits. Methods: Data were extracted from the literature, the Global Burden of Disease 2019) study, and Eurostat. We estimated the cases of cancer attributable to workplace exposure to Cr(VI) by combining exposure-effect relationships with exposure data, and calculated related DALYs and health costs in scenarios with different occupational exposure limits. Results: With current EU regulations, 253 cases (95%UI 250.96–255.71) of lung cancer were estimated to be caused by Cr(VI) in 2019, resulting in 4684 DALYs (95%UI 4683.57–4704.08). In case the welding industry adopted 10 μg/m3, a decrease of 43 cases and 797 DALYs from current values is expected. The predicted application of a 5 μg/m3 limit would cause a decrease of 148 cases and 2746 DALYs. Current costs are estimated to amount to 12.47 million euros/year (95%UI 10.19–453.82), corresponding to 39.97 million euros (95%UI 22.75–70.10) when considering costs per DALY. The limits implemented in 2025 would lead to a decrease of 23.35 million euros when considering DALYs, with benefits of introducing a limit value occurring after many decades. Adopting a 1 μg/m3 limit would lower costs to 1.04 million euros (95%UI 0.85–37.67) and to 3.33 million euros for DALYs (95%UI 1.89–5.84). Discussion: Assessing different scenarios with different Cr(VI) occupational exposure limits allowed to understand the impact of EU regulatory actions. These findings make a strong case for adapting even stricter exposure limits to protect workers’ health and avoid associated costs.publishersversionpublishe

Probabilistic approach for assessing cancer risk due to benzo[a]pyrene in barbecued meat: Informing advice for population groups

<div><p>Background</p><p>Consumption of meat prepared by barbecuing is associated with risk of cancer due to formation of carcinogenic compounds including benzo[<i>a</i>]pyrene (BaP). Assessment of a population’s risk of disease and people’s individual probability of disease given specific consumer attributes may direct food safety strategies to where impact on public health is largest. The aim of this study was to propose a model that estimates the risk of cancer caused by exposure to BaP from barbecued meat in Denmark, and to estimate the probability of developing cancer in subgroups of the population given different barbecuing frequencies.</p><p>Methods</p><p>We developed probabilistic models applying two dimensional Monte Carlo simulation to take into account the variation in exposure given age and sex and in the individuals’ sensitivity to develop cancer after exposure to BaP, and the uncertainty in the dose response model. We used the Danish dietary consumption survey, monitoring data of chemical concentrations, data on consumer behavior of frequency of barbecuing, and animal dose response data.</p><p>Findings</p><p>We estimated an average extra lifetime risk of cancer due to BaP from barbecued meat of 6.8 × 10⁻⁵ (95% uncertainty interval 2.6 × 10⁻⁷ − 7.0 × 10⁻⁴) in the Danish population. This corresponds to approximately one to 4,074 extra cancer cases over a lifetime, reflecting wide uncertainty. The impact per barbecuing event on the risk of cancer for men and women of low body weight was higher compared to higher bodyweight. However, the difference due to sex and bodyweight between subgroups are dwarfed by the uncertainty.</p><p>Interpretation</p><p>This study proposes a model that can be applied to other substances and routes of exposure, and allows for deriving the change in risk following a specific change in behaviour. The presented methodology can serve as a valuable tool for risk management, allowing for the formulation of behaviour advice targeted to specific sub-groups in the population.</p></div

Benefit and risk assessment of fish in the Norwegian diet - Scientific Opinion of the Steering Committee of the Norwegian Scientific Committee for Food and Environment

Source at https://vkm.no/.In 2006, VKM published “A comprehensive assessment of fish and other seafood in the Norwegian diet”. The assessment supported the recommendation from Norwegian Health authorities to eat more fish both for dinner and on sandwiches. In an update of the assessment in 2014 VKM concluded that “the benefits from fish consumption clearly outweigh the negligible risk presented by current levels of contaminants and other undesirable substances in fish”. Because of new knowledge available, the Norwegian Food Safety Authority requested a new benefit and risk assessment of fish in the Norwegian diet in 2019. In the assignment, they asked VKM to answer the following questions: Which health consequences will it have for the Norwegian population if they: Continue with the same fish consumption levels as of today Increase the consumption of fish to match the recommendations given by the Norwegian Directorate of Health </uli
