Article from Farm Journal’s Pork, written by Jennifer Shike, highlights the potential risk for ASF to be transmitted through feed ingredients.
The potential for feed ingredients to serve as a vehicle for African swine fever (ASF) virus introduction to the U.S. remains a significant concern, said Gil Patterson, VMD, chief medical officer at veterinary technology company, VetNOW.
“It is imperative that channels through which high-risk livestock feeds and feed ingredients are imported into the U.S. from ASF-positive countries are identified and considered in the USDA’s ASF National Response Framework,” Patterson says in a summary of his recent publication in Transboundary and Emerging Diseases. 
With the recent announcement of ASF in the Dominican Republic on July 28 and in Haiti on Sept. 20, Patterson says it’s more important than ever to put up every guard possible to keep this virus out of the U.S.
Identify Risk
Patterson’s study demonstrates the use of a novel analytical tool he developed to categorically quantify pork products and potential high-risk feed ingredients that have entered the U.S. from ASF-positive countries over a five-year period (2016-2020). 
Data for this study were obtained at the United States International Trade Commission Harmonized Tariff Schedule (HTS) website, a publicly available website that provides transaction information on specific trade commodities between the U.S. and its international trading partners. 
In the study, 29 high-risk pork products or feed ingredients with the potential to be fed to pigs were analyzed. High-risk products and ingredients are those that previous research has shown to facilitate extended viral survivability, he notes. These products include soybean meal and oilcake, distillers grains, pet food, and pork sausage casings. 
Data were then exported into Microsoft Excel and organized into pivot tables to describe the quantity of each product by country of origin and Port of Entry (POE). The analysis focused on the 60 ASFV-positive countries as were reported at the time of publication by the World Organization for Animal Health (OIE) in December 2020.
How Many High-Risk Products Are Imported into the U.S.?
In 2020, a total of 486,902 metric tons (MT) of these high-risk products were imported into the U.S. from a total of 19 of the 60 ASFV positive foreign countries, Patterson says. 
A majority of imported animal feed ingredients came from India in 2020 (85.8%; 392,243 MT), whereas the majority of pork products and by-products were imported from Poland (21,191 MT, 70.6%).
