L'objectif de cette ???tude ???tait d'???valuer l'application d'eau chaude entre 76???C et 78???C et de 1,5% d'acide lactique sur la surface des carcasses de porc en vue d'une r???duction microbienne. Quatre traitements ont ???t??? utilis???s, T1, T2, T3 et T4 avec de l'eau ??? diff???rentes temp???ratures suivie ou non d'une aspersion d'acide lactique. Des ???couvillons ont ???t??? pr???lev???s sur des carcasses de porcs naturellement contamin???es au cours du processus normal d'abattage et les micro-organismes suivants ont ???t??? recherch???s: m???sophiles a???robies, ent???robact???ries, Escherichia coli, Salmonella spp. et E. coli 0157 par la m???thodologie conventionnelle et par les m???thodes alternatives PETRIFILM(TM) et TEMPO(R) . Aucun r???sultat positif n'a ???t??? obtenu pour E. coli O157. Salmonella spp. a ???t??? d???tect???e dans 5 (6,58%) des 76 carcasses ???chantillonn???es, et les s???rotypes trouv???s ???taient Thyphimurium, Agona et Derby. Le traitement qui a montr??? la meilleure r???duction du nombre de carcasses contamin???es est celui qui consistait ??? baigner les carcasses dans de l'eau ??? une temp???rature comprise entre 76???C et 78???C, puis ??? les asperger d'acide lactique ??? une concentration de 1,5 %.
