  • Background: Foot-and-mouth disease (FMD) is a highly contagious viral disease in livestock that has tremendous economic impact nationally. After multiple FMD outbreaks, the South Korean government implemented a vaccination policy for efficient disease control. However, during active surveillance by quarantine authorities, pig farms have reported an insufficient antibody positivity rate to FMD. Objective: In this study, the spatial and temporal trends of insufficiency among pig farms were analyzed, and the effect of the number of government veterinary officers was explored as a potential preventive factor. Methods: Various data were acquired, including national-level surveillance data for antibody insufficiency from the Korea Animal Health Integrated System, the number of veterinary officers, and the number of local pig farms. Temporal and geographical descriptive analyses were conducted to overview spatial and temporal trends. Additionally, logistic regression models were employed to investigate the association between the number of officers per pig farm with antibody insufficiency. Spatial cluster analysis was conducted to detect spatial clusters. Results: The results showed that the incidence of insufficiency tended to decrease in recent years (odds ratio [OR], 0.803; 95% confidence interval [95% CIs], 0.721-0.893), and regions with a higher density of governmental veterinary officers (OR, 0.942; 95% CIs, 0.918-0.965) were associated with a lower incidence. Conclusions: This study implies that previously conducted national interventions would be effective, and the quality of government-provided veterinary care could play an important role in addressing the insufficient positivity rate of antibodies.

  • A study was conducted to determine the susceptibility of swine to Korean foot-and-mouth disease virus (FMDV; subtype O, isolated from Chungju province) in April, 2ooo. One holstein cow was inoculated intradermolingually with suspension of homogenized tissue from a Korean native cow naturally infected with Korean FMDY. Infected cow was housed with one susceptible cow and one susceptible pig (contact sentinels). Four additional susceptible pigs were housed in the same room but caged separately (non-contacted sentinels). The contacted pig and cow as well as non-contact pigs developed typical clinical signs after 2, 3, and 7 days post exposure, respectively. We compared neutralizing antibody from the animals to FMDV $O_1$ Lombardy, O Taiwan, $O_1$ Campos, and $O_1$ Manisa after 0, 4, 7, 10, 14, 21, 28 days post challenge and post-exposure. The highest viral neutralization titer could be interpreted that serotype O Korea (Chungju isolate) is antigenically more related to $O_1$ Manisa. In addition, immunohistochemistry was used to further characterize Korean FMDV from tissues of infected pigs. Korean FMDV antigen was observed in the tongue, hoof, esophagus, and tonsil tissues of sentinel pigs. These findings suggest that Korean FMD virus isolated from cattle can be rapidly transmitted to pigs both directly and indirectly contrast field observation in which only cattle were clinically ill.

  • This study evaluated the effect of a combination of acetaminophen and vitamin C (CAV) on reducing serum cortisol and tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$) concentrations in piglets vaccinated with foot-and-mouth disease (FMD) vaccine. Piglets were vaccinated with FMD vaccine and treated with CAV at concentrations of 0.0, 0.5, 1.0, and 2.0 kg/ton feed (P-CON, AD-1, AD-2, and AD-3, groups, respectively) for 5 days post-vaccination. Cortisol and $TNF-{\alpha}$ levels at 5 days post-treatment in the AD-1-3 groups were significantly lower than that in the P-CON group (p < 0.05). There were no significant differences between AD-2 and AD-3 groups and non-vaccinated, non-CAV-treated piglets.

  • This report describes a case of foot and mouth disease (FMD) in farm-raised Sika deer. FMD serotype A occurred in six cattle farms in January 2010 since the outbreak of pig cases 2002 in South Korea. In addition to the six cattle farms where the disease occurred during January, positive reactions to FMD antibodies were found in two heads of deer on March at a deer farm in serological tests intended to lift the movement restriction of the susceptible animals imposed within risk zone. In the specimens collected from 12 heads for confirmatory tests in the same farm, no virus was detected in antigen tests and neutralising antibody titers in all raising deer in the farm were relatively high. So it seems likely that the animals had been infected with FMD at least one month earlier when they were found.

  • Foot-and-mouth disease (FMD) is a infection that can easily spread when it occurs and causes serious economic damage because of the existence of multiple serotypes of the virus and extreme contagiousness. The most effective method in preventing the transmission of FMD virus (FMDV) is the culling of livestock and additional vaccination in the other areas depending on the spreading rate and situation. Diagnostic methods are utilized not only for the definite diagnosis of FMD but also for identification of serotype, and confirmation of antibody production after vaccination. Although many methods have been developed to diagnose, they are not still enough to detect accurately the disease in a short time. Therefore, it has been needed new diagnostic methods improved from existing methods. Previous methods were based on the enzyme-linked immunosorbent assay (ELISA) as a serological diagnostic method, or polymerase chain reaction (PCR), which is a molecular genetic method. The recent technology has been performing about the combination of both methods and how to make it faster, less costly, more sensitive and accurate way.

  • In 2010-11 outbreak of foot-and-mouth disease, around 3.5 million livestock were slaughtered and buried at more than 4,500 landfill sites. These landfill sites have been managed according to the Domestic Animal Infectious Disease Control Law. However, the control will be removed from December 2013 since the control period is 3 years. That means the sites will be reused without any interference. In this situation, if the buried livestock has not fully resolved and opened to surface, many dangerous happening is expected. This study explores technology and policy measures to meet the expected problems after December 2013. We will suggest the structure of technology for management of landfill sites based on the needs of the sites, and we will analysis Korean patents under this classification. This is the first try in the world because Korean style of landfill is unique. Based on analysis, we will suggest policy recommendations.

  • The ex-post evaluation of governmental crisis management is an important issues since it is necessary to prepare for the future disasters and becomes the cornerstone of our success as well. In this paper, we propose a data cube model with data mining techniques for the analysis of governmental crisis management strategies and ripple effects of foot-and-mouth(FMD) disease using the online news articles. Based on the construction of the data cube model, a multidimensional FMD analysis is performed using on line analytical processing operations (OLAP) to assess the temporal perspectives of the spread of the disease with varying levels of abstraction. Furthermore, the proposed analysis model provides useful information that generates the causal relationship between crisis response actions and its social ripple effects of FMD outbreaks by applying association rule mining. We confirmed the feasibility and applicability of the proposed FMD analysis model by implementing and applying an analysis system to FMD outbreaks from July 2010 to December 2011 in South Korea.

  • Foot-and-mouth disease (FMD) is an infectious disease affecting pigs. The control of FMD in swine husbandry is very important because its outbreak results in a vast economic loss. FMD vaccination has effectively controlled FMD; however, it results in economic loss associated with the incidence of lesions in the pork meat at the injection site. The objective of this study was to investigate the effects of transdermal needle-free injection (NFI) of the FMD vaccine on the incidence of lesions at the injection site. Pigs (n=493) in the control group were vaccinated with the FMD vaccine using a commercial syringe needle, while 492 pigs in the transdermal NFI group received the FMD vaccine using a needle-free gas-powered jet injector. After the slaughter of the pigs, the incidence of lesions at the injection site of all pigs was checked by plant workers. The result of this study showed that the incidence of lesions in the pork ham from pigs vaccinated with NFI was 14.82% lower than that in control pigs (p<0.01). In addition, lesions generated in the NFI group were found just in the subcutaneous tissue. Therefore, the incidence of lesions at the injection site in pork from pigs vaccinated with the FMD vaccine can be effectively reduced by using transdermal NFI rather than a conventional syringe needle.
