Determining the Risk of African Swine Fever in Vitamins

Are you asking the right questions about where your feed ingredients come from? On April 26, the Swine Health Information Center (SHIC) and the University of Minnesota invited vitamin and premix manufacturers to gather for a discussion on vitamins and the process involved prior to delivery to a producer’s farm with a special focus on African swine fever (ASF) transport and transmission risk.

 

Vitamin suppliers are responsible for ingredient safety to 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, according to the executive summary from this meeting.

 

“The workshop was convened to look at vitamins and premixes produced in areas of the world that have diseases foreign to the U.S. that might pose a risk to U.S. pig health if imported,” says Paul Sundberg, DVM, executive director of SHIC. “One of the points of discussion of the workshop was about quality control procedures for both human and animal grade vitamins. It was pointed out that manufacturing plants are generally dedicated facilities in urban areas with third party certification programs in place.”

 

One of the participants, Jon Bergstrom, senior technical support manager at DSM Nutritional Products, says vitamins for food and feed are produced in secure facilities. Most vitamin manufacturers produce human and animal grade vitamins using the same quality assurance and controls that meet human grade standards.

 

“Premier suppliers are already producing vitamins in accordance with high standards, certifications and verifiable quality audits. Premier suppliers often apply the highest accepted standards recognized globally for quality and safety,” Bergstrom says.

 

Participants agreed, however, that a comprehensive description of the entire vitamin supply chain is needed. Many vitamins are produced exclusively in China, while some are also primarily produced in China by a few manufacturers.

 

Although most meeting participants consider the risk of ASF introduction from vitamins to be low, they also believe that, if contaminated, some vitamins could be a vehicle for virus introduction into the U.S. Understanding the supply chain for every ingredient, especially essential ingredients that cannot be sourced locally, is increasingly important.

 

“An improved understanding of the vitamin supply chain will provide greater transparency about the high quality and safety standards that premier suppliers have already been using for many years,” says participant Jon Bergstrom, senior technical support manager at DSM Nutritional Products. “Pork producers will become more confident in sourcing safe, quality vitamins that provide the greatest value with the least amount of risk.”

Research on Viral Transmission in Feedstuffs Yields New Information

Ames, Iowa – May 7, 2019 – With research confirming that swine viruses can be transmitted through feed and feedstuffs, new studies are looking at how to prevent the spread of foreign animal diseases, such as African swine fever (ASF), via these vehicles. Based on new research, the Swine Health Information Center (SHIC), the National Pork Board, the National Pork Producers Council and the American Association of Swine Veterinarians have revised the information for feed holding times.

 

The Institute for Feed Education and Research (IFEEDER), the public charity of the American Feed Industry Association, helped fund the research that resulted in the updated information that provide the best and most current understanding of viral survivability in feedstuffs and details for mitigating risk to domestic herds.

 

“The science on viral transmission through feed and feedstuffs is still relatively young, but it has yielded some interesting and potentially useful information on mitigating the spread of costly viruses, such as ASF,” said Paul Sundberg, DVM, Swine Health Information Center executive director. “This includes recognition that not all imported feedstuffs are manufactured and handled in the same way. It’s important to know whether ingredients are produced under biosecure conditions and how they were shipped.”

 

The new details decrease holding times over the initial estimations, which were calculated in October 2018 based on the available research, and give additional assurances of further viral degradation if the feed ingredients are contaminated.

 

“Variations of the same feed components might cause disparity in holding time confidence,” said David Pyburn, DVM, National Pork Board senior vice president, science and technology. “For example, according to research using Senecavirus A (Seneca Valley virus), which is suggested to have the longest holding time of studied viruses, increasing holding times by an additional 30% would give an opportunity for 99.999% degradation of contaminating viruses.”

 

More research would be needed to confirm that the results could be extrapolated to other feed ingredients in like classes to those studied. The updated information shows new holding times details for general informational and educational purposes. They should not be considered as to be recommending or advocating any specific course of action.

“Continued diligence on feedstuffs origin, the manufacturing processes, the shipping methods and ‘born on date’ is essential,” Liz Wagstrom, DVM, National Pork Producers Council chief veterinarian, said. “Feedstuffs manufactured, sealed, handled, and shipped under biosecure conditions produces an ingredient free of pathogens and reduces the risk of post-processing contamination, resulting in little to no risk to animal health.”

 

For example, vitamins and amino acids are typically shipped in sealed or secure containers. Anything produced under unknown conditions or unsealed can pose an animal health risk. Imported soybean meal and DDGS are often transported in non-sealed or non-secure containers. Knowing the origin of ingredients and the disease status of the region or country is essential.

 

“The feed industry is a committed partner in the effort to prevent foreign animal diseases from entering the U.S. through imported feed ingredients,” said Leah Wilkinson, vice president for public policy and education for the American Feed Industry Association. “This additional information on holding times is helpful. We encourage dialogue with your feed ingredient or feed supplier to discover all of the measures that have been put in place to supply a safe product.”

The National Pork Board has responsibility for Checkoff-funded research, promotion and consumer information projects and for communicating with pork producers and the public. Through a legislative national Pork Checkoff, pork producers invest $0.40 for each $100 value of hogs sold. Importers of pork products contribute a like amount, based on a formula. The Pork Checkoff funds national and state programs in advertising, consumer information, retail and foodservice marketing, export market promotion, production improvement, science and technology, swine health, pork safety and sustainability and environmental management. For information on Checkoff-funded programs, pork producers can call the Pork Checkoff Service Center at (800) 456-7675 or check the Internet at pork.org.

Use of Chinese animal feed in US raises concern as killer swine disease rages abroad

 

·         American pork producers are using feed from China for their pigs, raising concerns about bringing a contagious disease to the U.S.

·         African swine fever has devastated China’s hog herd and has spread to other parts of Asia.

·         “Feedstuffs can carry it, and one of our concerns is we bring in vitamins and trace minerals for our pork industry from manufacturers in China,” says Steve Meyer of Kerns & Associates in Iowa.

·         The fear is it could spread to U.S., where it could devastate the more than $20 billion pork industry.

American pork producers are using feed from China for their pigs, raising concerns about bringing a contagious disease to the U.S.

 

At least 129 cases of the African swine fever in China have been reported since August, and the incurable viral disease has spread to other parts of Asia, including Vietnam and Mongolia. The fear is it could reach the U.S., where it could devastate the more than $20 billion pork industry.

 

“Feedstuffs can carry it, and one of our concerns is we bring in vitamins and trace minerals for our pork industry from manufacturers in China,” said Steve Meyer, an industry expert with Kerns & Associates in Iowa. “If you get the virus in those things, they can survive for a while.”

 

For example, Meyer said the so-called organic soybean meal — known for its high protein content — is shipped from China and typically fed to organic livestock, including to hogs. So far, the U.S. and Canada haven’t banned imports of plant-based food from China, but some experts have recommended a quarantine on imported feed of at least 20 before using it.

 

“They are still bringing it in, but it can be done in a responsible manner,” said Meyer. “We’re still concerned that somebody won’t be responsible, and I’d [be a] whole lot happier if we had regulations and stuff that allowed all that to happen on our shores.”

 

China accounted for about 12% of all soybean meal the U.S. imported from abroad in 2018 although India was another significant source of the animal meal, according to WISERTrade, a Massachusetts-based trade research organization.

 

“Animal feed ingredients and fomites have the potential to be pathways associated with a moderate likelihood of [African swine fever virus] entry, but there is high uncertainty because of the lack of data on transmission from these sources,” a recently published report from the the U.S. Department of Agriculture assessing the likelihood of swine fever entry to the U.S.

 

A meeting was held in Ottawa last week where U.S., Canadian and Mexican pork industry and government officials met to coordinate efforts to prevent the spread of the highly contagious swine fever into North America.

 

“We’ve never had this disease here in the United States, we don’t ever want to have this disease,” said Dr. Dave Pyburn, a veterinarian and vice president of science and technology at the industry trade group National Pork Board. “If we were to get it, it would be devastating for our pigs.”

 

The U.S. currently exports just under 30% of its pork, which could be at risk if the swine fever reached the domestic market, Pyburn said. He said the disease only affects pigs and not people.

 

Along with infected feed, experts say the swine disease can be spread by pigs’ bodily fluids and their meat as well as feral hogs and the animals eating uncooked garbage. Blood-sucking ticks also can carry the virus and spread it to swine...
