Mitigating the risk of African Swine Fever virus entry into boar studs in the USA

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.

This week the Secure Food Systems Team at the University of Minnesota shares information on a proactive risk assessment regarding the introduction of ASF via boar studs. To learn more about risk assessment regarding ASF introduction via feed, read our Science Page from last week.

Rethinking the uncertainty of African swine fever virus contamination in feed ingredients and risk of introduction into the United States

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.

The University of Minnesota shares their quantitative risk assessment framework to estimate the risk of African swine fever virus from imported contaminated feed ingredients, including soybeans and corn.

Streptococcus equi subsp. zooepidemicus associated with sudden death of swine in North America

This week, Dr. Matheus Costa from the University of Minnesota in collaboration with Dr. Brad Lage from Maple Leaf Agri-Farms share a case of sudden death due to Streptococcus equi subsp. zooepidemicus.

Key Points

Historically described as a commensal of the swine upper-respiratory tract, Streptococcus equi subsp. zooepidemicus was only reported previously in Asia as an important swine pathogen.
Here we report the isolation and whole genome characterization of Streptococcus equi subsp. zooepidemicus associated with a sudden death outbreak in pigs in North America.
