If animal disease, i.e., livestock foot-and-mouth disease, avian influenza, brings out, animals have to be disposed to prevent the virus spreading. Mainly, animals have been disposed by carcass disposal. However, If not done properly, carcass disposal can lead to environmental problems, i.e., soil and ground water pollution, etc. Therefore, various disposal methods, i.e., rendering, cremation, etc., have to be considered with burial. Also, various supplement policies are needed to prevent the animal disease. The purpose of this study was to find effective solutions for the prevention and biosecurity of animal disease.

In the livestock industry, detecting environmental outliers and predicting data are crucial tasks. Outliers in livestock environment data, typically gathered through time-series methods, can signal rapid changes in the environment and potential unexpected epidemics. Prompt detection and response to these outliers are essential to minimize stress in livestock and reduce economic losses for farmers by early detection of epidemic conditions. This study employs two methods to experiment and compare performances in setting thresholds that define outliers in livestock environment data outlier detection. The first method is an outlier detection using Mean Squared Error (MSE), and the second is an outlier detection using a Dynamic Threshold, which analyzes variability against the average value of previous data to identify outliers. The MSE-based method demonstrated a 94.98% accuracy rate, while the Dynamic Threshold method, which uses standard deviation, showed superior performance with 99.66% accuracy.

South Korea is susceptible to foreign diseases due to its high rate of livestock importation. The purpose of this study was to investigate the infectious conditions of contagious disease of horses imported into South Korea from other countries. The horses were tested for contagious equine metritis (CEM), equine infectious anemia (EIA), equine piroplasmosis (EP), equine viral arteritis (EVA), vesicular stomatitis (VS), dourine, and glanders. The prevalence of these infectious diseases in 6,650 horses imported from 24 countries between 2003 and 2008 was reviewed by the National Veterinary Research and Quarantine Service. Seropositive results were found for EIA, EP, EVA, dourine and glanders: 3/6,189 serum samples tested were EIA-positive, 37/6,005 samples tested by complement fixation (CF) were EP-positive, 28/6,043 samples tested by virus neutralization (VN) were EVA-positive, 4/2,071 serum samples tested by CF were positive for dourine, and 4/1,950 samples tested by CF were positive for glanders. No contagious equine metritis or vesicular stomatitis was detected. In total, 76/6,650 imported horses tested positive for an infectious disease. Notably, 4/6 sera (66.6%), all taken from horses imported from Tanzania, were positive for glanders. This is the first report of glanders infection in horses from Tanzania since 1996.

In the event of an outbreak of a livestock epidemic, it has been considered that the existing burial-centered carcass disposal method should be improved ecofriendly for prevention of leachate and odors from burial basically in regard of pathogen inactivation. Therefore, the aim of this study is whether it was possible to treat the carcass of cattle and chickens using the chemical carcass treatment method. It was conducted to establish detailed treatment standards for the chemical treatment method of cattle and chicken carcasses based on the results of the proof of the absence of infectious diseases in cattle chickens. After inoculating cattle carcass with 10 pathogens (foot and mouth disease virus, bovine viral diarrhea virus, Mycobacterium bovis, Mycobacterium avium subsp. Paratuberculosis, Brucella abortus, Bacillus anthracis, Clostridium chauvoei, Clostridium perfringens, Escherichia coli, and Salmonella Typhimurium) and chicken carcasses with low pathogenic avian influenza virus, Clostridium perfringens type C, E. coli and Salmonella Typhimurium, these were treated at 90℃ for 5 hours in a potassium hydroxide liquid solution corresponding to 15% of the body weight. This method liquefies all cadaveric components and inactivates all inoculated pathogens by PCR and culture. Based on these results, it was possible to prove that chemical treatment of cattle and chicken carcasses is effective in killing pathogens and is a safe method without the risk of disease transmission. The chemical treatment method of livestock carcasses can be suggested as an alternative to the current domestic burial-centered livestock carcass treatment method, preventing environmental pollution, and contributing to public health.

The prevalence of major zoonotic diseases such as tuberculosis, brucellosis and the highly pathogenic avian influenza (HPAI) in Jeonbuk province was monitored from 2004 to 2008. For tuberculosis, a total of 306 heads from 92 farms were positive during the surveillance period, which 228 heads were from 78 dairy farms and 78 heads from 14 Hanwoo farms. Based on the number of recurrent tuberculosis in 92 positive farms, 28 farms or 43.8% of the positive farms had 1-4 additional outbreaks during the surveillance. Based on brucellosis surveillance of 5,252 dairy cattle and 2,600,829 Hanwoo conducted during the same time period, 4,818 heads from 1,203 farms were positive for brucellosis, which 445 heads were from 111 dairy farms and 4,373 heads from 1,092 Hanwoo farms. Among the 1,203 positive farms, 473 farms or 39.3% of the positive farms had experienced 1-4 recurrent brucellosis during the surveillance. According to nationwide surveillance of HPAI, a total of 45 cases had been reported between 2004 and 2008. Among those outbreaks, 20 cases were reported in Jeonbuk province and 3 cases in 2006 and 17 case in 2008. For the regional distribution of 20 cases in Jeonbuk, 4 cases (48,490 chickens), 4 cases (23,066 chickens 66(1) and ducks 23,000(3)), 11 cases (183,077 chickens 63,077 (10) and quails 120,000 (1)), and 1 case (9,000 ducks) were reported in Iksan, Jeongeup, Gimje and Sunchang, respectively.

Brucellosis is one of the zoonoses, and it is a disease that is almost eliminated in South Korea. This disease is also known as a representative disease of one health. We would like to introduce brucellosis found by one health in this study. One Health means an approach in which multiple sectors communicate and work together to achieve better public health outcomes. The Gyeongbuk Agricultural Safety and Health Center established a cooperation system between a Veterinary Service Laboratory and a Public Health Center, and found a case of human brucellosis in a farm with cattle brucellosis. Through this case, to be effective control of zoonoses as above case, epidemiological investigation for cattle and human should be concurrently conducted. And we once again recognized the need for multi-sectoral cooperation in prevention and management of zoonoses.

Many burial sites were constructed to suppress the spread of foot and mouth disease during outbreak. Defected burial sites were removed when leachate leak is presumed and carcasses were moved to the circular storage tanks. However, carcasses were not decomposed possibly due to low water content, low microbial activities, and poor mixing. In this research, storage tank containing carcasses in it was modified to bioreactor to accelerate stabilization. Liquids with nutrients were added and circulated to maintain the optimum water content while extraneous microorganisms were augmented. Settlement was used as the primary index for assessing stabilization rate, and the consolidation theory was utilized to estimate the expected final settlement. 30% of carcasses is expected to be decomposed and removed from the storage tank for five years of bioreactor operation.

Coxiella burnetii is an obligate intracellular rickettsial organism and the causative agent of Query fever, a zoonosis that occurs worldwide. In Korea, C. burnetii infection had occurred in humans and animals. However, the studies were only conducted in geographically limited area for detection of C. burnetii. The objective of this study was to detect C. burnetii in Korean native cattle and dairy cattle nationwide by real-time PCR. The total of 807 blood samples from 622 Korean native cattle and 185 dairy cows, 170 individual milk samples of dairy cows, and 348 bulk tank milk samples of dairy herds were collected nationwide. From blood samples, C. burnetii was detected in 17 (2.7%) out of 622 Korean native cattle and 2 (1.1%) of 185 dairy cows. From milk samples, C. burnetii was detected in 27 (15.9%) out of 170 individual milk samples of dairy cows. And C. burnetii was detected in 84 (24.1%) of 348 bulk tank milk samples. In conclusion, this study revealed that the detection rates are considerably high in cattle and the infection of C. burnetii has been continuously occurring in cattle of Korea. In order to prevent the hazards of a zoonosis Q-fever that occur both humans and domestic animals, further studies are needed to clarify the epidemiology of Q-fever of domestic animals and humans in Korea.
