The Swine Health Information Center funds the Morrison Swine Health Monitoring Project and shares key deliverables derived from its activities. In December 2025, upon review of MSHMP’s 2025 accomplishments and proposed 2026 objectives, the SHIC Board of Directors renewed funding for 2026. MSHMP gathers information on the health of the US swine herd from more than 30 production systems participating voluntarily, analyzing data to track disease trends and monitoring for emerging pathogen activity. Led by principal investigator Dr. Cesar Corzo and the MSHMP team at the University of Minnesota, MSHMP delivers reliable and consistent swine health monitoring data for the US industry.
In the MSHMP summary of 2025 key outcomes, Dr. Corzo noted the US swine industry dealt with PEDV twice in 2025 across two epidemics. Both epidemics occurred in the fall/winter seasons, consistent with historical reporting. However, the last time two PEDV epidemics occurred in one year was in 2022.
The 2024-2025 and current 2025-2026 PRRSV seasons followed a similar trend as PEDV, with growing frequency of detection. New variants such as the L1C.5.32 were tracked as causing higher losses in affected herds. During 2025, MSHMP developed and launched the Variants Under Monitoring (VUM) initiative to better inform and aid industry stakeholders about PRRS variant activity. Through the VUM project, MSHMP characterizes and groups newly emerged variants into different categories based on the number of new sites affected in the previous six months. These VUM reports are featured in SHIC’s monthly newsletter.
During 2025, the MSHMP team focused on database improvements to enable more informed disease metric calculations. As part of this effort, the team focused on influenza quantification by estimating cumulative incidence. While improvement for breeding herd classification is still needed, Dr. Corzo said they have confirmed that estimation of cumulative incidence is feasible within the current MSHMP framework.
