Every bag of seed you develop, produce, test, or ship represents years of innovation, investment, and commitment.
When those seeds cross international borders, they carry something just as valuable as genetics. They carry your reputation.
For the past 25 years, the National Seed Health System has been helping you protect that reputation.
Whether you’re a seed company opening new export markets, a laboratory delivering accurate diagnostics, a researcher developing better testing methods, or a regulator working to safeguard agriculture, you’re part of a system built on one common goal: ensuring healthy seed can move safely and confidently around the world.
Administered by the Iowa State University Seed Science Center under the authorization of USDA APHIS, the NSHS exists because the seed industry recognized that science, consistency, and collaboration are essential to maintaining global trust. Today, that partnership is stronger than ever.
When the program launched in August, 2001, five organizations earned accreditation. Today, 28 accredited entities work together under a common framework that gives international customers confidence in U.S. seed. That confidence does not happen by accident. It’s earned every day by the people throughout our industry who are committed to producing healthy, high quality seed.
The challenges facing seed movement have changed dramatically over the past two decades. Global trade continues to expand. New pathogens emerge. Climate conditions shift. Import requirements evolve. Yet your customers still expect the same thing: confidence that every shipment meets the highest phytosanitary standards.
That’s why continuous innovation matters.
Together, we’re advancing faster molecular diagnostics, validating new testing methods, and developing technologies that improve both speed and accuracy. Current work on seed extract qPCR assays for diseases such as Goss’s Wilt is just one example of how industry, researchers, and regulators continue to work side by side to solve tomorrow’s challenges before they become tomorrow’s barriers.
Just as important is the work happening beyond our borders. Through collaborations with organizations like the International Seed Health Initiative (ISHI) and the International Seed Testing Association (ISTA), you’re helping shape internationally harmonized testing standards that reduce unnecessary trade barriers while maintaining strong plant health protections.
That collaboration benefits everyone, from seed companies and farmers to regulators and, ultimately, consumers around the world.
As we celebrate the 25th anniversary of the National Seed Health System, this milestone belongs to you. It belongs to the companies that embraced accreditation, the laboratories that upheld rigorous standards, the scientists who continually improved diagnostics, and the regulators who believed that science should guide policy.
The next 25 years will bring new challenges, but they will also bring new opportunities. By continuing to invest in innovation, collaboration, and scientific excellence, you’re ensuring that U.S. seed remains among the most trusted in the world.
The National Seed Health System is more than a program. It’s a partnership, and your commitment has made it one of the greatest success stories in global seed trade. Together, we’re not just protecting seeds. We’re protecting confidence, expanding opportunity, and strengthening the future of agriculture.
