For the examination of the bacterial contamination rate on each processing steps in the chicken processing plants, the CH chicken processing plant located on Chung Buk province was selected. All the general bacterial contamination rate on each processing steps of CH proceccing plant were compared with the microbiological standard of chicken processing plant in Japan. Seven of seventeen processing steps on the CH plants were failed to meet microbiological standards of Japan for general bacterial contamination. Especially, the mean contamination rate of interior surface of the chiller and scalder was over 1.0×105 cfu/cm2 which was much higher than standards of Japan.
The coliform contamination rate of the most processing steps were fairly low. The Staphyloccus species contamination rate on each processing steps was fairly high on the earlier steps especially, 1st and 2nd treated water of chiller, and gradually decreased in the latter processing steps. Exclusively the contamination rate of processed chicken after final chilling was very low.
On the examination of the pathogenic bacterial contamination on the 23 processing steps, Listeria monocytogenes was highly isolated bacteria and isolated from 8 process steps of 24 process steps. The Campylobacter jejuni and Staphylococcus aureus were isolated from 7 and 6 processing steps, respectively. Salmonella species was isolated from only 3 processing steps and was least contaminated pathogenic bacteria in this examination.
The mean productive index of 383 broiler farms which were under CH chicken integration system was 189.6 which is similar to those of national average in Korea. To find the correlation between productivity index and pathological lesion scoring of the chickens processed, 11 different determinants including the size of Fabricius bursa were observed on the chickens which were processed in the CH chicken processing plant.
The most significant changes among the 11 determinants before evisceration was observed on the twisted sternum which had mean of 1.57 with fairly large standard error, 1.03, interpreted to be big differences among farms. After the productivity index was gradually classed by 5 unit, the productivity index was compared with the 4 factors of productivity index such as average body weight, feed convulsion, mortality and the total days required on market weight. Among the factors of the productivity index, both the average body weight and feed convulsion index were positively correlated with productivity index. There was no correlation between productivity index and the number of Newcastle disease or Infectious Bursal disease vaccination. Although both pericarditis and the lesion severity of liver were not correlated with productive index, the degree of stunting, perihepatitis and the variation degree of Fabricius bursa size are fairly correlated with productive index.
Total 16 CCPs has been selected for applying HACCP to the each process steps of the national chicken processing plants. Among them 7 CCPs have been selected as CCP-1 which should be checked and monitored daily, 3 CCPs as CCP-2 which should be checked and monitored every other day, and finally 6 CCPs as CCP-3 which is relatively less important and should be checked and monitored by every week at least. Based on this classification of above CCP, the generic HACCP model for chicken processing plant has been developed.
