Sustainability takes center stage at 2025 World Pork Expo

While the aroma of bacon and baby back ribs filled the air at the Iowa State Fairgrounds at the 2025 World Pork Expo, the hungry crowds weren’t just there to be delighted by the culinary faire on display. They were also hungry to learn, network and collaborate about the third most consumed meat in the United States: pork. According to the Pork Checkoff program, the U.S. produces 11% of the world’s pork. In addition, in 2024, U.S. pork exports surpassed $8.6 billion in value.

The World Pork Expo is held over two days every June at the Iowa State Fairgrounds in Des Moines, Iowa, and is sponsored by the National Pork Producers Council. Thousands of producers, processors and pork industry professionals gathered at the annual Expo, where the latest in swine genetics, feed innovation, and sustainable farming practices took center stage in a celebration of modern hog production.

The world’s largest pork industry-specific trade show brings together pork producers and industry professionals from around the world, for pork industry innovations, educational insights and networking opportunities. But the World Pork Expo isn’t just a trade show—it’s the gathering point for all things pork.

“World Pork Expo is always a great place to share ideas and recharge,” said Doug Fricke, director of trade show marketing at NPPC. “This year, the energy was incredible — from both attendees and exhibitors. Everyone was excited to connect, learn and be part of the conversations shaping pork’s future.”
