FDA approves technology used to breed PRRS-resistant pigs

The US Food and Drug Administration (FDA) announced it has granted approval to PIC for the gene edit used in its PRRS-resistant pig, determining that the technology is safe and effective. This is a landmark approval, as PIC becomes among the first companies to gain approval for gene editing in commercial livestock in the US. However, PIC noted that FDA approval does not automatically trigger commercialization in the US.

“We have spent years conducting extensive research, validating our findings and working with the FDA to gain approval,” said Matt Culbertson, PIC’s Chief Operating Officer. “Today marks a major milestone for consumers, farmers and the entire pork industry who have desperately hoped for a solution to PRRS.”

The FDA-approved gene edit will be used to breed PIC’s PRRS-resistant pigs, which are resistant to Porcine Reproductive and Respiratory Syndrome (PRRS), one of the most devastating, global swine diseases.

“Addressing PRRS can allow us to improve animal welfare and reduce the environmental impact of raising pigs,” said Banks Baker, Global Director of Product Sustainability. “Recent research indicates that PRRS increases the need for antibiotics by more than 200%. Plus, a recent ISO-conformant lifecycle assessment found that eliminating PRRS could reduce greenhouse gas emissions by 5% in the U.S.”

Video: Season 6, Episode 10: Defining Resiliency and the Research Driving Swine Health Forward

Genetic research and new technologies continue to influence the future of swine health and production efficiency. In this episode, we explore how research and technology are being used to support stronger, more resilient pigs, while also improving overall production outcomes. In this episode, we are joined by Dr. Jenelle Dunkelberger, geneticist with Topigs Norsvin, to discuss both routine and emerging strategies for improving piglet, pig, and sow livability. She outlines two primary approaches to enhancing resiliency: gene editing and traditional selective breeding. Continuing the resiliency conversation, we also hear from Dr. Lucina Galina, director of technical research projects at the Pig Improvement Company. She shares insights into ongoing gene-editing work focused on PRRS, detailing the pathway to success, regulatory and practical considerations, and the questions that still remain as the technology evolves. Together, these conversations provide a closer look at how research, genetics and innovation are shaping the future of swine health and livability.
