Le risque biologique se définit comme le danger que représentent certains agents biologiques pour la santé de l’être humain. Le risque peut être infectieux, toxique, parasitaire. Parmi ces agents biologiques, on compte les bactéries, virus, champignons et parasites. Ils sont présents dans l’environnement : dans les eaux, les sols, les objets contaminés et les êtres vivants. Hommes, animaux et plantes peuvent être les porteurs.

Du fait de leur présence dans l’environnement, ils constituent un risque lors des activités de la vie quotidienne et professionnelle. Certains métiers sont plus vulnérables à ces agents biologiques comme les métiers de la santé, de l’agriculture et des industries agroalimentaires… mais certaines activités du bâtiment et des travaux publics exposent aussi les personnes à des agents biologiques.
