The National Pork Board has responsibility for Pork Checkoff-funded research, promotion and consumer information projects and for communicating with pork producers and the public. The Pork Checkoff funds national and state programs in consumer education and marketing, retail and foodservice marketing, export market promotion, production improvement, science and technology, swine health, pork safety, and environmental management and sustainability. For the past half century, the U.S. pork industry has delivered on its commitment to sustainable production and has made significant strides in reducing the environmental impact of pig farming. Through a legislative national Pork Checkoff, pork producers invest $0.35 for each $100 value of hogs sold. Importers of pork products contribute a like amount, based on a formula. For information on Checkoff-funded programs, pork producers can call the Pork Checkoff Service Center at (800) 456-7675 or visit porkcheckoff.org.
