International Symposium strengthens networking, fills gaps for systems to manage mass animal mortalities.
The 5th International Symposium on Managing Animal Mortalities, Products, By-Products and Associated Health Risks was held Sept. 28 – Oct. 1, 2015 in Lancaster, Pa. Through presentations, tours, hands-on activities and networking opportunities, participants were able to discuss effective plans and methods aimed at protecting animal health, human health, economies, communities and our environment during routine and emergency animal mortality management. Symposium participants also were encouraged to strengthen new and existing networks in order to identify current gaps or capability challenges in animal mortality management and work together to develop solutions.
“We wanted our participants to think about creating systems that work effectively and quickly to manage mass animal mortality events,” said Dale Rozeboom, Ph.D., Michigan State University professor and extension specialist and Symposium Chair. “Gaps can exist in many areas – from depopulation, disposal and decontamination to administration of response, funding availability and communication between national, state and local government agencies.”
Keynote speaker Tim Goldsmith, DVM, MPH, DACVPM, University of Minnesota College of Veterinary Medicine assistant professor and co-director of the Veterinary Public Health and Preventative Medicine Residency Program, explained the
importance of understanding risk in planning for and responding to catastrophic animal disease and how meetings like the Symposium are crucial for providing the tools needed to manage risk.
“Risks associated with catastrophic animal disease go beyond the health of the animal – it affects people, communities, and industries,” Goldsmith said. “Zero risk is not possible and we shouldn’t strive for zero, but, we need to look at the risk management possibilities out there for activities with significant risk in order to lower those risks to an acceptable level for all stakeholders involved in the management of a disease event.”
Tim Rueter, Ph.D., Livestock Research Branch of Alberta Agriculture and Forestry, spoke about managing high-risk pathogens through composting. Another plenary speaker, Patrick Webb, DVM, director of swine health programs at the National Pork Board, explained lessons learned in the swine industry and its recent experience with an outbreak of Porcine Epidemic Diarrhea Virus. Webb described response strategies and methods used for managing mortality and morbidity during an emerging disease outbreak significantly impacting swine production and the effects of the disease on U.S. pork producers.
The Symposium began with a day-long tour of Pennsylvania’s diverse agriculture industry – including dairy, beef, poultry and swine operations. Participants were able to see biosecurity procedures, routine composting, anaerobic digestion and in-vessel mortality composting at different local farms. Tour locations also included livestock truck wash sanitation stations that are vital to biosecurity and the health of people and animals involved in the farm’s operations.
Attendees also visited the Southeast Agricultural Research and Extension Center in Landisville, Pennsylvania. Demonstrations were hosted by experts and showed emergency windrow composting, carcass reduction, portable vehicle wash systems, wastewater treatment systems and humane euthanasia methods for livestock and poultry. The demonstration of techniques and challenges of foam euthanasia of poultry was particularly relevant, as many of the participants have been actively involved in response to the recent Highly Pathogenic Avian Influenza (HPAI) outbreak in the U.S. flock.
HPAI was further explored through a producer’s viewpoint with plenary speaker Mark Van Oort, complex manager for the Center Fresh Egg Farm – one of America’s leading egg producers. Van Oort guided Center Fresh Egg Farm through the 2015 outbreak of HPAI with a response that included large-scale euthanasia, carcass disposal, manure disposal and virus education through composting, control of a quarantine zone to control virus spread, and large scale cleaning and disinfecting.
“Immediately, I had planned to compost the birds,” Van Oort said. “We had dabbled in composting a bit before but not with 7.3 million birds – more like seven. We had to develop a cookbook and become resourceful . . . There were many lessons learned throughout this crisis and it’s certainly something that we hope to not have to deal with again.”
In order to understand the issues and to apply research opportunities and lessons learned from the 2015 HPAI outbreak response, the Symposium’s emergency exercise focused on response to a notional HPAI outbreak. Through breakout sessions and participating in facilitated scenario discussions, participants analyzed the notional outbreak on multiple levels (single farm, multiple farms, state, nationally and internationally) and identified issues and research opportunities related to depopulation, disposal, cleaning and decontamination and business continuity plans for the management of realistic issues that may occur during an outbreak.
Symposium planning committee members Edward Malek, Ontario Operational Specialist for Animal Health, Canadian Food Inspection Agency, and Duncan Worsfold, Statewide Specialist in Animal Emergency Preparedness, Agriculture Services and Biosecurity for the Department of Economic Development, Jobs, Transport & Resources of Echuca, Victoria, Australia, served as moderators for the exercise. The two envisioned that this emergency exercise would not only allow the participants to understand lessons learned, but also better prepare attendees to gather information and concepts for the development of collaborative discussions that may apply should an outbreak like this happen in their area in the future.
The Symposium’s focus extended beyond the U.S. borders through an international panel of experts who convened to discuss their perspectives and experiences on animal mortality management. This session included a plenary address from Heekwon Ahn, Ph.D., associate professor in the Department of Animal Biosystems Science at Chungnam National University in South Korea, who discussed his experiences and the response of the South Korean government during the 2011 South Korea Foot and Mouth Disease outbreak. The panel included representatives from: Vietnam, the Republic of Georgia, Australia, South Korea, Tunisia, the United Kingdom, Canada and Nigeria.
Technical presentations explored new and emerging technologies for euthanasia, carcass treatment and disinfection, carcass management, federal and state planning, disease mitigation strategies, depopulation and disposal and all hazards. The Symposium also included exhibits and software demonstrations.
Though the Symposium has concluded, the group’s work continues. Over the next year, the planning committee will produce a white paper for the U.S. Department of Homeland Security (DHS) and continue to collaborate with participants in order to advance the preparedness of the industry for a mass animal mortality event.
