The hazard analysis critical control point (HACCP) system was introduced to the Korean livestock slaughter and product processing business in 1997. Ice cream manufacturers focus on the sterilization process in order to reduce microorganism, so the HACCP-accredited ice cream manufacturers particularly set the sterilization process as critical control point (CCP). Therefore, the microbiological test results on the finished products can be considered as one of the indicators which show the level of microbiological control in the ice cream manufacturers. Accordingly, this study was carried out to examine if there is a meaningful difference in terms of the microbiological control level between the HACCP-accredited and non-accredited ice cream manufacturer groups by comparing aerobic plate count (APC) of ice creams. The mean of APC was 1.68 Log CFU/g in the HACCP-accredited ice cream manufacturer group and 2.59 Log CFU/g in the non-accredited ones respectively and there was a statistically significant difference (P<0.05). The test results suggest that the level of microbiological control in the HACCP-accredited ice cream manufactures is much higher than that of non-accredited ones.

The Autofom is a equipment for predicting the amount of pig carcasses meat using the 16 ultrasonic sensors to measure in real time and it was established in Dodram LPC in Gyeonggi Province of Korea for the first time. This study was carried out to validate the reliability of Autofom statistically and to establish guideline for developing a analytic formula through comparing the measurement between Autofom and dissection. The ham parts of sixty-six pig carcasses were measured with Autofom and by two experimental performers. The weight means and standard deviations of ham parts including bone by measurements with Autofom and dissection were 10.69±0.81 kg and 10.77±0.94 kg, respectively a strong positive correlation (P<0.01) was identified, with a coefficient of determination (R2) of 0.82. The weight means and standard deviations of lean ham parts by measurements with Autofom and dissection were 7.41±0.58 kg and 7.42±0.89 kg, respectively a strong positive correlation (P<0.01) was identified, with a coefficient of determination (R2) of 0.72. The root mean square errors of two groups were 0.40 and 0.50, respectively.

Three serotypes (O+A+Asia1 type) of the foot-and-mouth disease (FMD) vaccine were injected into cloven-hoofed animals in Korea after the nationwide spread of FMD at the end of 2010. This study was conducted to investigate FMD antibody development after FMD vaccination, and to determine whether there was a significant correlation between the antibody titer of the sow and the antibody titer of the growing pigs. The antibody titer (percentage inhibition [PI] titer) of the sow (gilt) after FMD vaccination was maintained at a level higher than 50 (P<0.05) for 5 months. A higher PI titer for the 1-month-old growing pigs corresponded with greater inhibition of the PI titer of the vaccinated growing pigs (P<0.05). A negative correlation (P<0.05) between the PI titer of the 1-month-old growing pigs and the PI titer of 3-month-old growing pigs, 4-month-old growing pigs after FMD vaccination at 2 months, 3months was identified, with a coefficient of determination (R2) of 0.274. Thus the PI titer of the growing pigs was inhibited to a greater degree when vaccination was performed at 2 months of age than at 3 months. However, many other factors likely influence growing pigs` PI titer in addition to the PI titer of the sow and age at vaccination, given that the coefficient of determination was somewhat lower.
