Today, we are sharing a recently published review article by the Torremorell lab, available in Frontiers in Veterinary Science. This review article opens with a summary and historical perspective of Highly Pathogenic Avian Influenza (HPAI) H5N1 cases in avian species as well as in dairy cows. It makes the case that considering the high mutation rate of IAV and the potential for spillovers in swine, a One Health approach including human, animal and environmental health needs to be taken. Information regarding experimental infections and field observations of HPAI H5N1 in pigs as well as strategies for diagnostic and surveillance, implications for biosecurity and management practices to control the virus are included. Lastly, authors explain the associated concerns for public health.

H5 Influenza Q&A with Drs. Marie Culhane and Carol Cardona
H5 Influenza is in the news and many swine professionals have questions and concerns around recent outbreaks in dairy cattle and the potential for cross-species spread. We have answers to many of your questions, addressed by Dr. Marie Culhane, one of the UMN Swine Group’s Influenza experts and Dr. Carol Cardona, avian influenza expert and the UMN CVM Pomeroy chair in Avian Health.

This article was written by Catherine Dehdashti and originally published in the University of Minnesota Extension's Magazine Source. Since this piece has been written, the first case of H5N1 influenza has been reported in a non-commercial pig in Oregon. Read Dr. Marie Culhane's comments in this article.
Like Minnesota, the state of Texas is strong in livestock. But Minnesota, including University of Minnesota Extension’s livestock team, has long led in research and education on preventing the spread of disease among farms, especially since the 2015 outbreak of H5N1 highly pathogenic avian influenza and the 2024 spread of avian influenza into dairy cows.

Podcasts are a perfect way to get caught up with new swine information! We are presenting you the latest episode from “At The Meeting.”
In this episode of “At The Meeting,” Dr. Dustin Oedekoven, chief veterinarian for the National Pork Board, talks about the serious threat posed by Highly Pathogenic Avian Influenza (HPAI) and what it means for the swine industry. The discussion touches on the virus’s recent spread to dairy cattle, the crucial role of biosecurity measures, and the steps the industry needs to take to prevent outbreaks. Don’t miss this episode for an in-depth look at the current challenges and strategies for safeguarding swine health.

Dr. Marie Culhane is Professor at the University of Minnesota College of Veterinary Medicine who specializes in Influenza and emergency disease preparedness and management. The poultry industry has battled outbreaks of High Pathogenic Avian Influenza (HPAI) in recent years and as the old saying goes, “Your friends challenges are your cheapest learning opportunities”. We go in depth with Dr. Culhane on Influenza – what makes this a “shared disease” between humans, birds and pigs, what are the common control strategies employed across species and how can vaccine platforms help manage Influenza disease. We specifically focus on HPAI outbreaks and their analogies with reportable diseases in the swine industry. Poultry producers have had major HPAI outbreaks in 2015 and again now in 2022 – how have their biosecurity programs and diagnostic tools evolved over that period? How do they effectively implement control zones and permit requirements prior to movement? Ultimately, what have they done to improve the timeline from diagnosis to depopulation from 7 days to 36 hours from 2015 to 2022? Marie shares lessons learned about smallholder poultry operation management that correlates to similar smallholder swine operations as well as perspective about wild bird management akin to our challenges with feral swine management.
