Rethinking the uncertainty of African swine fever virus contamination in feed ingredients and risk of introduction into the United States

During the acute phase of the African Swine Fever Virus (ASFV) epidemic in China, complete feed, and feed ingredients from three mills were tested for ASFV DNA by PCR. Across mills, the percentage of positive sample pools detected in complete feed ranged from 0.5% to 1.2%, and from 0.2% to 1.8% in feed ingredients, including positive pools of wheat, rice, corn, and soy samples. This is the first report of ASFV contamination in feed under commercial conditions in China.

Policies And Practices

With monetary support from the United States Department of Agriculture Foreign Agricultural Service (USDA FAS), an investigative effort was undertaken to document the biosecurity practices employed by commercial pig producers in Ukraine to prevent the introduction of African swine fever virus (ASFV) on their farms. The cohort of farms selected and evaluated were owned by producers who were active members of the Association of Ukrainian Pig Breeders (AUPB). The assessment of biosecurity policies and practices consisted of an interview and in-person completion of a questionnaire that evaluated various aspects of biosecurity practices used on pig farms in Ukraine. The results of the interviews and completion of survey questionnaires support the conclusion that Ukrainian pig producers recognize the importance of farm biosecurity as it relates to preventing ASFV introduction on their farms and all the participating farms had biosecurity policies that were in force at the time of completion of the questionnaire. However, the results also support the conclusion that significant gaps in understanding about biosecurity exists and that there is a need for more education of Ukrainian pig producers about this critical aspect of health management and disease control. The broad impact of the project detailed that prospective, more comprehensive work on Ukrainian pig farms is required to adequately assist producers with ASFV control and effective applications of biosecurity

The Stability

Since the 2013 introduction of porcine epidemic diarrhea virus into the United States (U.S.), feed and feed ingredients have been recognized as potential routes for the introduction and transmission of foreign animal diseases of swine. Feed ingredients for swine diets are commodities traded worldwide, and the U.S. imports thousands of metric tons of feed ingredients each year from countries with circulating foreign animal diseases. African swine fever (ASF) is the most significant foreign animal disease threat to U.S. swine production, and the recent introduction of ASF into historically negative countries has heightened the risk for further spread. Laboratory investigations have characterized the stability of the ASF virus (ASFV) in feed ingredients subjected to transoceanic shipment conditions, ASFV transmissibility through the natural consumption of plant-based feed, and the mitigation potential of certain feed additives to inactivate ASFV in feed. This review describes the current knowledge of feed as a risk for swine viruses and the opportunities for mitigating the risk to protect U.S. pork production and the global swine population from ASF and other foreign animal diseases.
