Q&A: Pork, pathogens and progress—a close look at PRRSV research

The pork industry provides people across different cultures a considerable source of protein, essential nutrients and a versatile ingredient for diverse culinary traditions. So, when the problem of porcine reproductive and respiratory syndrome virus (PRRSV) infection in the pork industry results in an economic loss of $650 million annually in the United States, finding a solution is of critical significance.

A diverse group of researchers at the Faculty of Science and Leiden University Medical Center, The Netherlands, recently published a paper sharing their discovery on better understanding and managing PRRSV. The following interview is with Dr. Brian Mark, professor at the department of microbiology and dean of the Faculty of Science, who leads a laboratory focused on understanding the molecular basis of diseases.

The Next Mile, host Dr. Meredith Petersen, Director of Swine Health at the National Pork Board, sits down with Dr. Cara Haden, Director of Animal Welfare and Biosecurity at Pipestone, to unpack the National Swine Health Strategy and what it means for producers across the country.

Meredith walks through how the strategy came together: a producer-led effort launched in March 2025 in response to input gathered at the National Pork Industry Forum, built around two core goals, keeping foreign and emerging diseases out of the U.S. herd and reducing the impact of domestic diseases already here, including long-term elimination targets for PRRSV and PEDV.

Cara then brings the conversation down to the farm level, sharing how Pipestone scores biosecurity across seven key areas: air, feed, water, people, supplies, trucks and pigs, plus everything within the farm perimeter. She and Meredith dig into why farm leadership and daily culture, not just protocols on paper, ultimately determine whether biosecurity efforts stick.

Whether you're a producer, veterinarian, or anyone invested in herd health, this episode offers a grounded look at where the industry is headed and what everyday habits make the biggest difference.
