Trade Update • May 6, 2026
Key Points
- Canada imposed import restrictions on specific U.S. swine by-products following confirmed pseudorabies outbreaks in Iowa and Texas.
- The USDA suspended export certification for raw inedible swine by-products, untreated swine blood products, and raw swine manure.
- Shipments that have already been certified are still allowed to enter Canada.
- Imports of edible pork products and raw pet food containing pork may continue because they do not present a transmission risk.
- USDA confirmed the first known pseudorabies case in U.S. commercial swine since the disease’s eradication in 2004.
Canada introduced temporary import restrictions on certain U.S. swine products after the U.S. Department of Agriculture (USDA) confirmed pseudorabies cases in commercial swine herds in Iowa and Texas. The restriction applies to raw inedible swine by-products, untreated swine blood products, and raw swine manure. The USDA won’t be issuing export certificates for these products until further notice.
Meanwhile, shipments that have already been certified may still enter the country. Also, other swine commodities, including edible pork meat and raw pet food containing pork products may continue because officials said these products do not spread the disease.
First Commercial Swine Case Since 2014
According to the USDA website, the Animal and Plant Health Inspection Service (APHIS) confirmed antibodies to pseudorabies virus (PRV) in a small commercial swine facility in Iowa through Enzyme-Linked Immunosorbent Assay (ELISA) and latex agglutination testing.
Federal investigators traced the affected boars to an outdoor facility in Texas, where additional animals also tested positive. USDA officials continue traceback investigations with state authorities to identify possible exposures and limit further spread.
According to APHIS, this marks the first known case of pseudorabies in U.S. commercial swine since the disease was eradicated from the industry in 2004.
While the virus affects pigs and some mammals, humans, horses, and birds are considered resistant. Officials also emphasized that the outbreak does not affect the safety of the commercial pork supply.
