Abstract:
Control of Salmonella cross contamination in slaughter processing plant is one of the main factors in pig meat production process. From pig slaughter house processing flow, major slaughter processes are consisting of stunning, bleeding, scalding, dehairing, carcass cutting, and chilling. Although the major processes are the same in good manufacturing practice (GMP) certified slaughter house, details of work in each major step are different in each slaughter. Therefore, the study was aimed at comparing efficacy of Salmonella control on different slaughter process in GMP and hazard analysis and critical control point (HACCP) certified pig slaughter houses. Study was conducted in 3 pig slaughter houses and each slaughter houses were visited twice to collect swab and water samples at before and after each control point on major processing step. Water sample was also collected at critical control point. It was found that the average numbers of Salmonella on skin swab samples after stunning process were accounted for 44.40% of total samples. Salmonella serovar isolates were S. Rissen (4.76%), S. Weltevreden (2.38%) and S. Kedougou (0.79%). Salmonella was not detected on any other samples. In conclusion, different slaughter process in GMP and HACCP certified pig slaughters can be used to effectively control Salmonella cross contamination
