African swine fever (ASF) has spread from the Dominican Republic to Haiti, marking the first outbreak in the country since 1984, with 234 cases found among a herd of 2,500 animals. The World Organization for Animal Health (OIE) confirmed the outbreak in Anse-a-Pitre. In response, the USDA has stopped the flow of pork products from Puerto Rico and the U.S. Virgin Islands to the mainland U.S. as a precautionary measure. The disease, which does not affect humans but is fatal to pigs, first emerged in the Dominican Republic in July 2021. The outbreak in Haiti and the measures taken to prevent the spread of ASF to other areas highlight concerns about the disease's potential impact on global pork markets, especially considering the significant pork export revenue the U.S. achieved in 2020 and the early 2021 continuation of these high export volumes.
