Our previous research found that FMD Outbreaks in foreign countries have a significant positive influence on U.S. swine meat exports. However, not all of these FMD-affected countries adopted the same treatment policy to ease domestic FMD issues. This study proposes a gravity model with fixed-effect regressions to analyze the effects of FMD in countries that import U.S. swine meat. Annual trade data for seventeen countries are used in this study. This study confirms that different policies change the results from FMD. FMD-affected countries which adopted a vaccination policy have negative impacts on U.S. swine meat exports, and the estimated results did confirm that these seven countries are still very important swine meat markets for the U.S.
