🔍 Clinical, Sensory & Functional Diagnosis
Aucune altération visuelle, texturale ou olfactive du fromage ; danger sanitaire surveillé (entérite granulomateuse des ruminants et lien épidémiologique étudié avec la maladie de Crohn)
🧬 Biochemical, Enzymatic & Genetic Mechanism
Paroi cellulaire riche en lipides complexes et acides mycoliques (mycobactine-dépendante pour la subsp. paratuberculosis) empêchant la lyse acide et saline pendant plusieurs mois d'affinage
🌡️ Physicochemical Parameters & Target Matrices
Excrétion mammaire et fécale dans le lait cru et survie prolongée durant la fabrication et l'affinage • Troupeaux infectés par la paratuberculose, haute résistance thermique (survie partielle à la thermisation et à la pasteurisation basse en amas cellulaires) et tolérance à pH 4.5-5.0
🛡️ Cellar Protocol, Prophylaxis & Biocontrol
Certification et assainissement des cheptels vis-à-vis de la paratuberculose, hygiène stricte de la traite, microfiltration du lait et affinage prolongé
