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.

Evolution of Beef Cattle Farming

Video: Evolution of Beef Cattle Farming

The Clear Conversations podcast took to the road for a special episode recorded in Nashville during CattleCon, bringing listeners straight into the heart of the cattle industry. Host Tracy Sellers welcomed rancher Steve Wooten of Beatty Canyon Ranch in Colorado for a wide-ranging discussion that blended family history and sustainability, particularly as it relates to the future of beef production.

Sustainability emerged as a central theme of the conversation, a word that Wooten acknowledges can mean very different things depending on who you ask. For him, sustainability starts with the soil. Healthy soil produces healthy grass, which supports efficient cattle capable of producing year after year with minimal external inputs. It’s an approach that equally considers vegetation, animal efficiency, and long-term profitability.

That philosophy aligned naturally with Wooten’s involvement in the U.S. Roundtable for Sustainable Beef, where he served as a representative for the Colorado Cattlemen’s Association. The roundtable brings together the entire beef supply chain—from producers to retailers—along with universities, NGOs, and allied industries. Its goal is not regulation, Wooten emphasized, but collaboration, shared learning, and continuous improvement.
