Biosecurity – Swine in Minnesota

Evaluating on-farm sampling strategies for early detection of African swine fever

This is our Friday rubric: every week a new Science Page from the Bob Morrison’s Swine Health Monitoring Project. The previous editions of the science page are available on our website.

North Carolina State University researchers Jason A. Galvis, Aniruddha Deka and Gustavo Machado share their findings about the use of different sampling methods for early detection of ASFV in today’s Science Page.

What you need to know about pseudorabies

By the University of Minnesota Swine Group

The reporting on April 30, 2026 of pigs positive to pseudorabies in Iowa and Texas is a good reminder that we cannot be complacent when it comes to infectious diseases.

Pseudorabies virus (PRV) causes a devastating clinical picture resembling rabies in young pigs, thus the name. This disease, also known as Aujeszky’s disease, is most severe in piglets, causing high mortality as well as tremors, seizures, paralysis, incoordination and “dog-sitting” signs. As they get older, infected pigs experience respiratory disease with fever, coughing, and pneumonia. In sows, PRV causes abortions and stillbirths and in boars the virus can be shed in semen. PRV transmits primarily by direct contact with secretions of infected pigs but other routes such as exposure to contaminated fomites or aerosols can lead to infection.

Assessment of PEDV Trailer Contamination at the Harvest Facility

This is our Friday rubric: every week a new Science Page from the Bob Morrison’s Swine Health Monitoring Project. The previous editions of the science page are available on our website.

Researchers Lucas Ferreira, Mark Schwartz, Marie Culhane, and Cesar A Corzo from the University of Minnesota bring us today’s Science Page, looking at PEDv contamination of trailers at the slaughter house.

Partitioning, a novel approach to mitigate the risk and impact of African Swine Fever (ASF) in endemic settings

This is our Friday rubric: every week a new Science Page from the Bob Morrison’s Swine Health Monitoring Project. The previous editions of the science page are available on our website.

In this week’s Science Page Solenne Costard, Andres M. Perez, Francisco J. Zagmutt, Jane G. Pouzou, and Huybert Groenendaal share how partioning would contribute to the improved resilience and sustainability of the global pork industry.

Enhancing U.S. swine farm preparedness for infectious foreign animal diseases with rapid access to biosecurity information

This is our Friday rubric: every week a new Science Page from the Bob Morrison’s Swine Health Monitoring Project. The previous editions of the science page are available on our website.

In today’s Science Page Christian Fleming, Kelsey Mills, Nicolas C. Cardenas, Jason A. Galvis, Cesar Corzo, Denílson dos Santos Ebling, and Gustavo Machado look at the value of the Rapid Access Biosecurity application (RABapp™) as a centralized tool for standardizing and auditing biosecurity plans at a national scale.
