SHIC Funded MSHMP Annual Report Details Program Growth and Value to US Pork Producers

The Morrison Swine Health Monitoring Project, funded by the Swine Health Information Center, submitted its 2025 annual report for swine disease monitoring and project enhancements. Dr. Cesar Corzo, along with colleagues at the University of Minnesota, detail the outcomes from three project objectives for the past year. Key achievements include adding porcine deltacoronavirus to the list of monitored diseases, assessing requirements to include influenza A virus sequencing information for breeding herds, and supporting the dynamic porcine reproductive and respiratory syndrome virus variant classification system that serves as the basis for the PRRSV Variants Under Monitoring report. Further, project leaders report the continued expansion of producer participation in alignment with increasing inclusivity and representativeness. The MSHMP project data currently accounts for 3.9 million sows and represents approximately 65% of the US breeding herd. Read the full MSHMP report here. For 202Read More

Annual swine competition brings legislators, exhibitors together

The Ohio Department of Agriculture and the Ohio Pork Council recently hosted the annual Battle for the Bacon at the Ohio State Fair, where legislators and cabinet members teamed up with skilled 4-H and FFA swine exhibitors in the show ring. After an evening of friendly competition, State Senator Michele Reynolds (R-Canal Winchester) was named Grand Champion, while State Representative Johnathan Newman (R-Troy) earned Reserve Champion. “Ohio farmers feed Ohioans and feed the world, and these young exhibitors are the next generation to lead that effort,” said ODA Director Brian Baldridge. “This event is an incredible opportunity for legislators and leaders from across the state to learn about agriculture in a unique way and to better understand the hard work and dedication that these young exhibitors bring to the Ohio State Fair and to their communities.” The event highlighted Ohio’s pork industry while giving participants an inside look at handling techniques, show-ring etiquette, anRead More

Study finds MRV, PAdV present but low risk in U.S. pigs

The Swine Health Information Center funded a study to examine whether mammalian orthoreovirus and porcine adenovirus are present in U.S. swine herds and whether they pose health risks. Led by Wenjun Ma, University of Missouri, the study suggests that MRV and PAdV can infect pigs and contribute to general enteric disease but that these viruses are not associated with severe or unique clinical signs. These findings suggest that both viruses circulate in swine populations, with evidence pointing toward intestinal shedding or prior exposure rather than widespread active disease in routine tissue submissions. For producers and their veterinarians, this study helps interpret diagnostic findings on MRV or PAdV, enabling more informed herd health decisions. Emerging and re-emerging viral pathogens remain an ongoing threat to the U.S. swine industry, and undiagnosed disease outbreaks continue to highlight important gaps in pathogen surveillance and characterization. Although MRV and PAdV have Read More
