New SHIC research shows ASF remains infectious for much longer

Pork Checkoff reports that the new recommendation is to hold conventional soybean meal an average of 125 days from when it is “born” or packaged, up from only 52 days determined in previous research.

Transit time to the United States of potentially contaminated feed ingredients can be applied to the total holding time after the “born-on date” if the ingredient is transported in such a way that would prevent further contamination.

Experts recommend that you talk with your feed suppliers and ask for the born-on date for all imported feed products. Vigilance is the best prevention, so it’s good to review key tactics found in The Role of Feed and Ingredient Biosecurity for ASF Prevention on the pork.org/fad page.

To learn more about the original study on viral half-life, see Stability of SVA in animal feed ingredients at www.swinehealth.org/originalfeedholdingtime on the Swine Health Information Center website.

Also, find biosecurity guidelines in Developing Biosecurity Practices for Feed & Ingredient Manufacturing at www.swinehealth.org/AFIAbiosecuritypractices from the American Feed Ingredient Association website.
