Relative risk of transmission of ASF in imported soybean products

By Jerry Shurson and Pedro Urriola, University of Minnesota, St. Paul

Originally appeared in National Hog Farmer

African swine fever continues to be a significant threat to U.S. pork production, as well as corn and soybean growers. The introduction of a foreign animal disease may cause the U.S. losses of about $8 billion for the pork industry on the first year of an outbreak (Hayes et al., 2011; Lusk, 2019). However, the economic impact of an ASF outbreak would extend beyond the pork industry because the prices and revenue from production of corn ($44 billion) and soybeans ($25 billion) would also significantly decrease as a consequence of decreased utilization of these ingredients in swine diets (Hayes et al, 2011).

Most swine viruses tested in the Pacific and Atlantic transboundary models survived in soybean meal (Dee et al., 2018). In addition, porcine coronaviruses had the greatest survival in soybean meal compared to other feed ingredients (Trudeau et al., 2017).

Best practice to submit samples to UMN VDL

Do you need to submit samples to the UMN Veterinary Diagnostic Lab (VDL) and unsure how to submit proper samples? Good news....UMN VDL has put together a 1-page illustrated handouts to help you submit commonly used sample types. The "how-to" for each commonly used sample type is available in a downloadable PDF format.

The handouts can be found on UMN VDL's website.

Sow handling videos

Upper Midwest Agricultural Safety and Health Center (UMASH) worked with their partners National Pork Board, the UMN College of Veterinary Medicine and UMN Southern Research and Outreach Center at Waseca to develop two new training videos addressing sow handling and biosecurity measures to prevent influenza. The videos are available in English and Spanish and were designed as training tools for employees.

Be sure to check out the videos on UMASH's website.

African Swine Fever resources

The MN Board of Animal Health has new resources available to inform the public, producers, veterinarians and markets about how they can prevent African Swine Fever (ASF) and other swine diseases. The new fact sheets provide a background of ASF and how to prevent it with biosecurity. The fact sheets are available in multiple languages and are available on MN Board of Animal Health's website.

The MN Board of Animal Health has also created a "Know the signs of foreign animal disease" fact sheet aimed at hobby or small scale pig owners. These fact sheets have been distributed to select feed stores across MN. These fact sheets show clinical signs of ASF, foot and mouth disease and classical swine fever to raise awareness and encourage pig owners to contact a veterinarian if they suspect any of these viruses in their pigs.

Taking a look at African Swine Fever one year later

A year ago, on August 3, 2018, the Chinese government reported an occurrence of African Swine Fever (ASF) in their country. At that time, many North American producers and industry-affiliated folks had no idea about ASF. The disease was covered in veterinary textbooks and materials defining emerging & exotic diseases, but very few had seen it or had any experience with it.

Today we know much more about it. From the National Pork Board, these are the plain facts about this disease the United States' swine herd has never faced:
The virus is not dangerous to humans, it only affects pigs (domestic and wild).It is hardy and can survive for long periods - dried, frozen and cured pork products are at high risk of carrying the virus.The virus can be spread through feeding pigs swill containing undercooked contaminated pork.Adhering to strict farm biosecurity measures will decrease the cha…
