Abstract
Good Management practice (GMP) is a systematic, scientific approach that is tailored to prevent the incidence of any problem by making sure that the control procedures are applied at any point in a food production system where critical or hazardous situations might take place. Hazards can include chemical, physical, or biological contamination. It is necessary for each plant’s GMP team to draw his own model to fit the production, on basis of the knowledge they have for the process inside the plant. Several points should be taken in consideration when using the model to develop certain GMP plans.
The aim of this study is to determine the effect of application of GMP program in some steps of the slaughterhouse on meat quality through determination of microbial count before and after the application of GMP.
Also, this work was designed to examine the followings points:
Microbiological examination by examining the Aerobic Mesophilic count, coliform count, enterobacteriaceae count, and mould and yeast count before and after application of the GMP program in slaughterhouse.
This study was carried-out on samples that have been obtained through swab samples from the surface of 160 random samples (80 before application of the GMP and 80 after application of the GMP) collected from the different parts of the (slaughtering box, skin, evisceration station, meat) from an abattoir in Alexandria Province. The samples were put in separate inside sterile clean plastic bags and transferred with ice chambers that are insulated with less delay for further microbiological analysis to the laboratory. All samples were subjected to microbiological examination to make sure that they were fit for human consumption.
The present results indicated that:-
1- The results on the microbial counts of slaughtering box swabs samples (CFU/ cm2) before and after application of GMP cleared that, Aerobic Mesophilic Count (AMC) on the slaughtering box before application of GMP ranged from 8.1 × 103 to 1.05 × 104 with a mean value of 9.4 × 103, while, after application of GMP the AMC on the slaughtering box ranged from 3.7 × 103 to 4.4 × 103 with a mean value of 4 × 103. The reduction % of AMC due to application of GMP reached to 57 %.
Enterobacteriaceae count (EC) on the slaughtering box before application of GMP ranged from 2.1 × 103 to 3 × 103 with a mean value of 2.5 × 103, while, after application of GMP the EC on the slaughtering box ranged from 3 × 102 to 3.5 × 102 with a mean value of 3.1 × 102. The reduction % of EC due to application of GMP reached to 87 %.
Coliform counts (CC) on the slaughtering box before application of GMP ranged from 1 × 103 to 1.9 × 103 with a mean value of 1.5 × 103, while, after application of GMP the CC on the slaughtering box ranged from 3 × 102 to 3.5 × 102 with a mean value of 3.2 × 102. The reduction % of CC due to application of GMP reached to 78 %.
Mould and Yeast counts (MYC) level on the slaughtering box before application of GMP ranged from 1.25 × 103 to 1.75 × 103 with a mean value of 1.4 × 103, while, after application of GMP the MYC on the slaughtering box ranged from 3.1 × 102 to 4.3 × 102 with a mean value of 3.7 × 102. The reduction % of MYC due to application of GMP reached to 73 %.
2- The results of Microbial counts of skin swabs samples before and after application of GMP cleared that, there was a significant differences of the microbial counts before and after application of GMP.
Aerobic Mesophilic Count (AMC) on the skin before application of GMP ranged from 2.1 × 104 to 2.8 × 104 with a mean value of 2.3 × 104, while, after application of GMP the AMC on the skin ranged from 4 × 103 to 4.6 × 103 with a mean value of 4.1 × 103. The reduction % of AMC due to application of GMP reached to 82 %.
Enterobacteriaceae count (EC) on the skin before application of GMP ranged from 2 × 103 to 2.5 × 103 with a mean value of 2.2 × 103, while, after application of GMP the EC on the skin ranged from 3 × 102 to 3.5 × 102 with a mean value of 3.1 × 102 . The reduction % of EC due to application of GMP reached to 85 %.
Coliform counts (CC) on the skin before application of GMP ranged from 1 × 103 to 2.4 × 103 with a mean value of 1.7 × 103, while, after application of GMP the CC on the skin ranged from 3 × 102 to 3.7 × 102 with a mean value of 3.3 × 102 . The reduction % of CC due to application of GMP reached to 80 %.
Mould and Yeast counts (MYC) on the skin before application of GMP ranged from 1.5 × 103 to 2.3 × 103 with a mean value of 1.8 × 103, while after application of GMP the MYC on the skin ranged from 3.3 × 102 to 4 × 102 with a mean value of 3.7 × 102. The reduction % of MYC due to application of GMP reached to 79 %.
