Swine flu: how a new virus has taken over other genotypes in France

In 2020, a new genotype of swine influenza virus, responsible for swine flu, emerged in France and quickly replaced certain previous strains. Scientists at ANSES’s Ploufragan-Plouzané-Niort Laboratory conducted a study to understand how this rapid change could have occurred. The emergence of a new genotype poses a risk to the health of pigs and humans alike.

Foot-and-mouth disease: a step closer to understanding the persistence of the virus in ruminants

Foot-and-mouth disease is one of the most contagious viral animal diseases. It affects more than 70 domestic and wild species, in particular cattle, pigs, sheep and goats. Disease-free countries are not exempt, as has been shown by recent cases since January 2025 in Germany, Hungary and Slovakia. The disease has a major socio-economic impact on livestock sectors, both in areas where it is endemic and in the event of an incursion into a previously disease-free area. For more than 50 years, a complex question has been asked: in areas where the virus circulates, why is it able to persist in up to 50% of infected ruminants after their apparent recovery? ANSES's Laboratory for Animal Health sought to answer this question through FMDV_PersIstOmics, an international research project. This project revealed that one of the virus's proteins plays a key role in this persistence.

Analysis of the results of Inserm’s collective expert review on the health effects of pesticides

The adverse effects of plant protection products must be monitored and taken into account so that their uses and marketing authorisations can be adjusted where necessary. Through its phytopharmacovigilance scheme, ANSES analysed the results of a major scientific study: Inserm’s collective expert review on the links between pesticide exposure and human health, updated in 2021. Following this analysis, the Agency identified several health signals, including a strong signal concerning pyrethroids, which are used in plant protection products as well as in biocides and veterinary medicinal products. ANSES reiterates the importance of regularly reviewing the assessments of substances and products in light of new data.
Cases of nitrous oxide poisoning still on the rise

Cases of nitrous oxide poisoning still on the rise

Since 2020, reports of poisoning related to the misuse of nitrous oxide, or ‘laughing gas’, have been steadily increasing. This gas can lead to dependence and to severe, sometimes irreversible complications affecting the nervous and cardiovascular (heart and blood vessels) systems if taken repeatedly and/or in large quantities. Nitrous oxide is mainly consumed by teenagers and young adults: according to data from a Santé publique France survey, in 2022, 14% of 18-24-year olds had already tried it and more than 3% reported having consumed it within the last year. Not all of these young users are aware that it can be dangerous. In response to this public health issue, the ANSM, ANSES and Santé publique France are reiterating the measures that should be taken to prevent and manage the risks associated with nitrous oxide consumption.

ANSES to coordinate Green Data for Health (GD4H) in support of environmental health

On Wednesday 2 April 2025, a cooperation agreement was signed between the members of the Green Data for Health project (GD4H), entrusting ANSES with its coordination. GD4H brings together a community of French environmental health stakeholders, with the aim of facilitating the availability of environmental data and their cross-referencing with health data.
