African swine fever (ASF) is a contagious virus that kills pigs. People can’t get sick from it, but they can spread it. If ASF spreads, it could impact how much pork can be made and how much it costs. With the help of young farmers and pig owners, we can protect our pigs and prevent the spread of ASF.
