African Swine Fever virus can survive a simulated 30-day transoceanic voyage in contaminated plant-based feed and ingredients, a new study shows.

 

The study, conducted by veterinary researchers in the United States, looked at the degradation of African Swine Fever (ASF) virus in animal feed ingredients to understand the potential for disease spread through contaminated feed. The study was published in the journal Emerging Infectious Diseases.

 

ASF virus on a 30-day transoceanic voyage

 

The paper examined the possible risk of ASF virus spreading to the United States through imported feed. The study provides more accurate half-life measurements that confirm the virus can survive a simulated 30-day transoceanic voyage in contaminated plant-based feed and ingredients.

 

Lead author of the scientific article was assistant professor Megan Niederwerder, Kansas State University. In an article on the website of Kansas State Uni she commented, “This study provides additional evidence supporting the potential risk that feed may play in the transboundary movement of ASF. Our latest work provides robust half-life estimates, which include standard errors and confidence intervals, and characterises the stages of viral decay over time for ASF virus in animal feed ingredients.”
