Risques microbiologiques liés aux déjections et aux aires de vie des bovins

De nombreux agents pathogènes peuvent se transmettre ou être véhiculés par les déjections animales sous différentes formes (matières fécales, effluents, fumiers, lisiers…), à différents endroits (aire de vie des animaux, lieux de stockage des fumiers) et à différents moments (épandage, retournement des andains...).

Afin d’évaluer le risque microbiologique lié aux déjections et aux aires de vie des bovins, une meilleure connaissance des caractéristiques physico-chimiques de ces substrats, ainsi que de la capacité de survie de pathogènes d’intérêts dans ces mêmes substrats sont nécessaires.

Descriptif du projet : 2009-2011

L’objectif général est la production de connaissances et méthodes pour la maîtrise des risques microbiologiques liés aux déjections.
Pour ce faire, l’action est décomposée en 3 volets :

  • Volet 1- La connaissance physico-chimique des effluents (principalement fumiers) et mise au point de modèles;
  • Volet 2- La méthodologie d’échantillonnage pour déterminer les niveaux de contamination;
  • Volet 3- La modélisation prédictive pour la maîtrise;

Cet axe est momentanément suspendu d’ans l’attente de recrutement spécifique sur cette thématique.
