Item African Swine Fever-Soybean Meal Supply China Workshop – Workshop Summary and Supplemental Information(2019-07-10) Shurson, Gerald C; Urriola, Pedro E; van de Ligt, Jennifer LG; Sullivan, Polly L; Sundberg, PaulAn African swine fever-Soybean meal supply chain workshop involving key industry stakeholders was conducted on July 10, 2019 on the University of Minnesota St. Paul campus. The objectives were to 1) identify and discuss the various segments and potential risk factors of the soy supply chain in North America, 2) identify and discuss potential prevention, mitigation, and product differentiation (country of origin) strategies for soy products used in the U.S. pork industry, and 3) identify research and education needs related to foreign animal viruses and soy products. The group identified potential risk factors for African swine fever virus introduction into the United States through imported soy products including 1) contamination during transport, 2) inadequate virus inactivation in soybean hulls during processing if contaminated, 3) imported organic soybean products used in fertilizers, and 4) risk of virus spreading through manure and other routes if introduced. Prevention, mitigation, and differentiation strategies were discussed and included 1) develop a diagnostic test to assess African swine fever virus in feed, 2) explore alternatives to inter-port shipment of soybean products among U.S. ports of entry, and 3) identify and educate importers about consequences of African swine fever virus introduction and suggest prevention and mitigation methods. Several research and education outcomes were identified including 1) improve data collection on country of origin for imported soy products, 2) write a report describing the soy supply chain including reasons for imports and benefits of exports, 3) conduct more research on survivability of the virus in different feed ingredient matrices that is reproducible, 4) determine whether the virus is present in feed ingredient supply chains, 5) determine the most accurate methods to assess virus survival, and 6) determine specific factors that cause the African swine fever virus to survive in soybean meal for extended periods of time.Item African Swine Fever-Vitamin Supply Chain Workshop Notes(2019-04-26) Shurson, Gerald C; Urriola, Pedro E; van de Ligt, Jennifer LG; Sullivan, Polly L; Sundberg, PaulAn African swine fever-vitamin meal supply chain workshop involving key industry stakeholders was conducted on April 26, 2019 on the University of Minnesota St. Paul campus. Several vitamins are produced exclusively in China, while others are also primarily produced in China by a few manufacturers. Likewise, most vitamin manufacturers produce human and animal grade vitamins using the same quality assurance and controls that meet human grade standards. Most meeting participants consider the risk of ASF introduction from vitamins to be low but recognize that, if contaminated, vitamins can be a vehicle for virus introduction in the U.S. Several research and development priorities were identified including 1) develop a surrogate for ASF virus for monitoring processes that can inactivate the virus if it was present, 2) develop third party biosecurity modules and audits that can be implemented for feed ingredient manufacturers, 3) conduct a risk assessment of virus transmission throughout the vitamin supply chain, and 4) explore the use of blockchain technology for greater transparency and trust in the vitamin supply chain. Several education and communication priorities were also identified. A clear, transparent, and unified message is needed to educate the feed and pork industry to decrease confusion and suspicion of the perceived risks of virus transmission in the vitamin supply chain. Key components of this story include: 1) what is known about ASF virus characteristics, survival, and inactivation, 2) general description of raw materials, chemical and fermentation processes used to produce various vitamins, 3) current quality assurance programs, 4) packaging and transport, 5) potential for cross contamination from other porcine derived feed ingredients in multi-species feed mills, 6) approved sources vs. brokers and traders, and 7) holding times, origin of carriers, and premix manufacturing processes used before delivery to feed mills and commercial swine farms. Vitamin suppliers have industry wide standards for ingredient safety that minimize the opportunity for virus introduction. However, pork producers are responsible for knowing their suppliers and asking the right questions to screen potential suppliers that do not follow standards of safety. A comprehensive description of the entire vitamin supply chain is needed and a unified, accurate, and consistent message to the pork industry.Item Guidelines for developing a risk-based plan to mitigate virus transmission from imported feed ingredients(2019) Schettino, Daniella N; van de Ligt, Jennifer LG; Sampedro, Fernando; Shurson, Gerald C; Urriola, Pedro EThere is increasing concern regarding the risk of swine disease transmission via feed ingredients, whether imported or domestically produced. This risk may be reduced in the feed ingredient supply chain by identifying and implementing preventive controls (supply chain, sanitation, transportation, and process) at different steps of the chain. The objective of this study was to develop a practical guide to help feed ingredient suppliers and buyers to safely manufacture, package, transport, and use feed ingredients in swine feeding programs. The Food Safety Modernization Act (FSMA) provides the basis of this study because these regulations require proactive risk-based preventive control processes that are applied in the food supply chain to prevent or reduce the risk of hazards from being present in the final product. Using this conceptual framework, implementation of preventive controls in the feed production chain can control or decrease the potential introduction of foreign animal viruses through feed ingredients into the U.S. A decision tree was developed as a first step in identifying preventive controls and potential high-risk feed ingredient sourcing scenarios. A case-study using Porcine Epidemic Diarrhea virus (PEDV) and the corresponding decision tree was developed as an illustration on how to use this new approach. Although this approach is based on swine viral diseases, it can serve as a template for other pathogenic viruses and species.
