African swine fever now in the Dominican Republic North American swine producers and the related industry have been taking great pains over the past few years to keep African swine fever out of the United States. Although African swine fever is one of three foreign animal the U.S. livestock industry wants to keep out of the country, the other two — classical swine fever (CSF) and foot and mouth disease (FMD) have infected U.S. SWINE & U hogs and were eradicated long ago. CSF, also known as By Diane DeWitte hog cholera, was stamped out in 1978, and FMD, which affects all split-hooved animals, was eradicated in 1929. ASF has not yet infected U.S. swine herds. It has, however, made appearances in the western hemisphere. Cuba, the Dominican Republic and Haiti battled and eradicated ASF in their swine populations in the 1970s. What is African swine fever? African swine fever is one of the most severe diseases of pigs, having a drastic impact on the pig industry. ASF first appeared in domestic pigs in East Africa in the 1900s. It subsequently spread to Europe; appearing first in Portugal, then Spain and further countries. Eradication was achieved in Europe apart from Sardinia in the mid- 1990s. In 2007, ASF then appeared in Georgia — spreading then to Russia and the Caucasus region, and other eastern European countries. In 2018, it continued to spread westward, affecting domestic pig and wild boar populations. In 2018, ASF virus also reached the world’s largest pig producer: China. Mongolia reported its first outbreak in 2019. In the years since its outbreak in China, ASF has been identified in Southeast Asian counties and European countries, including Germany and Poland in wild boar populations in September of 2020. ASF is a h ighly-contagious hemorrhagic disease caused by a virus of the family Asfarviridae. I t is often fatal in domestic pigs and wild boars. The primary control strategy for ASF in domestic swine is stamping-out. Currently, there is no vaccine available. Given the financial implications and limitations in trade, eradication is the ultimate goal. ASF is a n otifiable diseaselisted by the World Organization for Animal Health (OIE) and must be reported. ASF virus is considered a F oreign Animal Diseaseby the United States Department of Agriculture and therefore swine byproduct imports from ASF-positive countries are forbidden. Any suspicion of ASF must be n otified to the Minnesota Board of Animal Health and the USDA.

Wed. Evening, September 1st • 6:10 PM Planning in place Swine producers and allied industry have put together strategies to monitor and prevent ASF from infecting North American pig populations, and Minnesota leads the charge. The University of Minnesota College of Veterinary Medicine swine team, along with Minnesota Pork Producers, the Minnesota Board of Animal Health, the Minnesota Judges: John Huinker, Brian Hines, Shari Sell-Bakker Department of Agriculture and U of M Extension Monday, August 30th have worked together as the Emergency Disease West Ring - 5:00 pm: Management Committee for Swine to implement a Junior Barrow Showmanship plan.

The plan developed strategies for action in the event that ASF would infect Minnesota, the Upper Midwest or the North American swine herd. In September 2019 fourteen swine-producing states worked together for four days through a functional exercise to determine what steps would be taken by all affiliated partners if ASF struck. Now in the Western Hemisphere On July 28, 2021, the USDA announced that it had identified ASF in samples from the Dominican Republic. USDA receives quarterly samples from a lab in the Dominican Republic, and originally identified eight samples positive for ASF. Further testing provided information that the ASF infection had spread further than the original results indicated. The Dominican Republic swine herd is produced in both larger, more commercial-type farms established on the eastern end of the island, and in small backyard settings (with 20 pigs or fewer) found throughout most of the regionals of the Dominican Republic. The positive samples were discovered in the smaller herds, many of which are loosely
