L\u2019Agence nationale de s\u00e9curit\u00e9 sanitaire de l\u2019alimentation, de l\u2019environnement et du travail (Anses) a rendu le 28 mai 2026 un avis relatif aux prolif\u00e9rations d\u2019Ostreopsis spp. sur le littoral basque, dans le cadre de la saisine n\u00b0 2025-AST-0078, li\u00e9e \u00e0 la saisine n\u00b0 2021-SA-0212. Cet avis fait suite \u00e0 une demande d\u2019appui scientifique et technique de la Direction g\u00e9n\u00e9rale de la sant\u00e9 (DGS) en date du 14 ao\u00fbt 2025. La DGS sollicitait notamment l\u2019Agence sur la possibilit\u00e9 d\u2019\u00e9tendre \u00e0 l\u2019ensemble du littoral fran\u00e7ais les recommandations d\u00e9j\u00e0 \u00e9mises par l\u2019Anses en 2023 concernant les risques pour la sant\u00e9 humaine li\u00e9s aux prolif\u00e9rations d\u2019Ostreopsis spp. sur le littoral basque.<\/p>\n
L\u2019Anses rappelle que sa mission consiste \u00e0 fournir une expertise scientifique ind\u00e9pendante et pluraliste pour \u00e9valuer les risques sanitaires dans les domaines de l\u2019environnement, du travail et de l\u2019alimentation, et \u00e0 appuyer les autorit\u00e9s comp\u00e9tentes pour l\u2019\u00e9laboration et la mise en \u0153uvre des dispositions l\u00e9gislatives et r\u00e9glementaires. Dans ce cadre, l\u2019Agence souligne que les conditions topographiques, hydrodynamiques et m\u00e9t\u00e9orologiques propres au littoral basque sont sp\u00e9cifiques et ne permettent pas, au vu des connaissances disponibles, de transposer directement \u00e0 l\u2019ensemble du littoral fran\u00e7ais les recommandations formul\u00e9es pour cette seule r\u00e9gion.<\/p>\n
Compte tenu de ces limites, l\u2019Anses indique qu\u2019il n\u2019est pas possible, en l\u2019\u00e9tat actuel des donn\u00e9es, de g\u00e9n\u00e9raliser les mesures ou recommandations bas\u00e9es sur la situation du littoral basque \u00e0 d\u2019autres zones c\u00f4ti\u00e8res fran\u00e7aises. En cons\u00e9quence, il a \u00e9t\u00e9 propos\u00e9 de reformuler la demande initiale de la DGS en une \u00ab demande d’appui scientifique et technique relatif aux prolif\u00e9rations d\u2019Ostreopsis spp. sur le littoral basque \u00bb, concentrant ainsi l\u2019analyse et les recommandations sur ce territoire sp\u00e9cifique. Les avis de l\u2019Anses, dont celui-ci, sont publi\u00e9s sur son site internet afin d\u2019\u00eatre accessibles aux autorit\u00e9s concern\u00e9es pour la gestion des risques sanitaires.\u00a0(contenu r\u00e9sum\u00e9 par l’IA)\u200bLire la Suite<\/a>\u200b<\/p>","protected":false},"excerpt":{"rendered":" L\u2019Agence nationale de s\u00e9curit\u00e9 sanitaire de
