Iowa Farmers And Pork Producers Show Their Support To Keep A Massive Trade Agreement With Mexico And Canada

By Rachel Cramer

Iowa farmers and pork producers are urging the U.S., Mexico and Canada to renew a massive trade agreement in the coming weeks.

The United States-Mexico-Canada Agreement (USMCA), which replaced the North American Free Trade Agreement (NAFTA) in 2020, includes a mandatory review on July 1. The three countries will decide whether to extend the USMCA for another 16 years, terminate the agreement or begin an annual review process starting in 2027, according to the Center for Strategic and International Studies.

Trade leaders from Canada and Mexico said earlier this week that they’d like to renew the USMCA through 2042. If the U.S. opts out, the USMCA will sunset in July 2036.

Bob Hemesath grows corn and raises hogs in northeast Iowa. At the World Pork Expo in Des Moines Wednesday, he moderated a roundtable with agricultural leaders in the state as board chairman of the nonprofit coalition Farmers for Free Trade.

“At a time when global competition is intensifying and market access is more critical than ever, the USMCA agreement remains a cornerstone of North America agriculture, trade and just economic impact overall,” Hemesath said. “For Iowa, that impact is tangible. Canada and Mexico account for a vast majority of our state's key export markets.”

Around 40% of Iowa’s goods are exported to the two countries, according to the Brookings Institute. The total value in 2023 was $8.9 billion with corn, soybeans, ethanol and tractors at the top of the list.

Genetics Behind Swine Resilience - Dr. Jenelle Dunkelberger

Video: Genetics Behind Swine Resilience - Dr. Jenelle Dunkelberger


In this episode of The Swine it Podcast Show Canada, Dr. Jenelle Dunkelberger, geneticist at Topigs Norsvin, explains how genetics can improve disease resilience in pigs. She explores how resilience differs from resistance, the role of genetic variation, and how breeding strategies can enhance health and performance under disease pressure. Dr. Dunkelberger also covers practical applications and future implications for swine production. Listen now on all major platforms!

"Controlled experimental trials confirm that differences in mortality and performance under disease pressure are linked to genetic background, even when environmental conditions remain consistent."

Meet the guest: Dr. Jenelle Dunkelberger / jenelle-dunkelberger-9200ab86 is a geneticist at Topigs Norsvin, where she leads the Global Health and Behavior Research Platform. She earned her PhD from Iowa State University, focusing on host genetics and disease response in pigs. Her work centers on improving swine health and performance through genetic selection for resilience and behavior traits.
