African Swine Fever – Swine in Minnesota

Assessment of ASF/CSF Sick Pig Surveillance at UMN and ISU Veterinary Diagnostic Laboratories

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 Rachel A. Schambow, Michelle L. Schultze, Leticia C. M. Linhares, Bret Crim, Albert Rovira, Hemant K. Naikare, Catherine Lorenz, Cole Vanicek, Rodger G. Main, and Andres M. Perez from the University of Minnesota, Iowa State University and the USDA bring us today’s science page.

Validation of the effectiveness of pig farm repopulation protocol following African swine fever outbreaks in the Philippines

In this recent publication from the Center of Animal Health and Food Safety, Dr. Hsu presents the protocols put in place in the Philippines to repopulate swine farms after African Swine Fever outbreaks and their success rates.

Risk assessment of the presence of PED and ASF viruses in spray-dried porcine plasma

Today we are sharing a new publication from a collaboration with our colleagues at the School of Public Health and the College of Agricultural and Natural Resource Sciences at the University of Minnesota. In this study, Drs. Sampedro, Urriola, Van de Ligt, Schroeder, and Shurson estimated the maximal viral load of Porcine Epidemic Diarrhea and African Swine Fever that could be found in spray-dried porcine plasma to still achieve a virus-free batch (no infectious viral particle) for three different batch sizes (10, 15, and 20 tons). They also quantified the impact of different treatments such as spray-drying, UV and extended storage in decreasing viral loads to meet the thresholds.

Space-time dynamics of African Swine Fever spread in the Philippines

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 Chia-Hui Hsu and Andres Perez from the Center for Animal Health and Food Safety, and Maximino Montenegro from the Pig Improvement Company in the Philippines, examine the spatial and temporal patterns of ASF in the Philippines between 2019 and 2022.

U of M researchers lead major African swine fever breakthrough

University of Minnesota researchers recently led successful efforts to work on African swine fever virus (ASFV), developing and validating a surrogate virus for ASFV that will help develop effective mitigation strategies to control ASFV and keep it from entering North America. The disease has devastated pig populations and pork production in countries around the world.
