Evaluation of Hazard Analysis and Critical Control Points Implementation in the Poultry Slaughter Houses

Abstract

To pinpoint the principal location for microbial contamination of fowl carcass during the preparation, sixty swabs specimens were taken while the slaughtering process was underway. These specimens were taken from different parts of the carcass (neck, leg, breast, wing and belly) in order to run the microbial count after defeathering, evisceration, washing and chilling steps, which are considered critical control points in the process. The findings revealed that there was average microbial contamination especially on the bellies it was 6.80cfu/ml, on the necks and legs it was 6.55cfu/ml and 5.64cfu/ml respectively, whereas on the breast was found to be 4.49cfu/ml and wings 4.80cfu/ml. The highest contamination of total bacterial count occurred at the evisceration step 6.54 cfu/ml, defeathering 4.99 cfu/ml, washing 5.15 cfu/ ml and at the chilling 4.99 cfu/ml. Counts for pathogenic bacteria; Salmonella, E. coli and Staphylococcus aureus and Coliforme was conducted. The highest average count was 267.29 cfu/ml for Coliform bacteria then the E. coli 30.19 cfu/ml and Staphylococcus aureus 10.22 cfu/ml. The Salmonella was found after defeathering, evisceration and washing steps, but not at all after chilling. To check the labour force as a source of contamination to the product, twelve swabs specimen were taken from their hands at the different steps of processing mentioned above. The average of the bacterial count was evident (5.55 cfu/ml) beyond dought. Also there was count for the pathogenic bacteria; the average for E.Coli was 13.00cfu/ml and Staphylococcus was vi 2.18 cfu/ml. The average for Coliform was 85.25cfu/ml. Salmonella was found at evisceration and washing, but not after defeathering and chilling. Knives as a source of contamination were swabbed sampled, and the average of the bacterial count was 4.02 cfu/ml. The average of the Pathogenic bacteria was detected as, 1.25 cfu/ml for Staphylococcus aureus, but Salmonella and E. coli were not there. Also the average for Coliform was 6.50 cfu/ml.
