1 Animal Disease Response Training Euthanasia and Disposal August 2010 AWR 206-1

2 Animal Disease Response Training Scope Statement Identify and explain the various methods of euthanasia and options for disposal of animal carcasses and address the operational, safety, and emotional elements associated with these activities.

3 Animal Disease Response Training Terminal Learning Objective Identify euthanasia and disposal measures that control, prevent the spread of, and eradicate animal disease.

4 Animal Disease Response Training Enabling Learning Objectives 4-1List effective methods and resources used for animal carcass disposal during an animal disease event. 4-2Identify personnel safety concerns associated with euthanasia and disposal procedures. 4-3Review the process of indemnification based on fair market value of destroyed animals and materials. 4-4Describe the content of on-site educational materials that will be provided to producers, farmers, and responders.

5 Animal Disease Response Training Euthanasia Activities & Incident Command

6 Animal Disease Response Training Health and Safety Considerations Monitors and observes risks unique to agriculture Alters, suspends or terminates unsafe acts or conditions How does the safety officer assist command?

7 Animal Disease Response Training Safety Issues Walking and working surfaces Slips, trips, and falls Heavy equipment operations Trench operations Animal restraint equipment Nighttime operations Burning operations Working with animals Euthanasia procedures Heat and/or cold stress Fatigue Mental and physical stress Working in inclement weather

8 Animal Disease Response Training Euthanasia Team Safety Size and body weight of animals Temperament of the species Animals generally regarded as dangerous Obscure operator vision and excessive noise Animals’ familiarity with humans Presence and demeanor of animal owner

9 Animal Disease Response Training Coping with Traumatic Events Any person exposed to depopulation and disposal operations may suffer negative impacts and manifest in one or more of the following areas: –Physical symptoms –Cognitive or thought disturbances –Emotional changes –Behavioral changes

10 Animal Disease Response Training Animal Welfare and Handling Euthanasia methods must be humane, safe, and appropriate to the species involved Guidance from Section 4 of AVMA Guidelines

11 Animal Disease Response Training Humane Animal Handling Animal handling help may be recruited from the local community –assistants should be briefed in safe work practices and non-abusive animal handling techniques Euthanasia Team Leaders will require additional personnel to accomplish their mission

12 Animal Disease Response Training How are appraisal and indemnification accomplished? Prior to euthanasia the animals should be appraised Confirmed by an animal heath authority Fair market value utilized

13 Animal Disease Response Training Euthanasia Process uses five common steps 1.Select most appropriate method 2.Select a site for euthanasia 3.Assess and request resources needed 4.Implement euthanasia 5.Withdraw from premises and prepare C&D and support to producer or farm

14 Animal Disease Response Training Physical Methods Euthanasia Captive bolt –Most practical in a mass euthanasia situation Gunshot –method of choice for loose housed animals –where physical restraint is impractical or unavailable Gunshot to the heart is not an approved AVMA method for euthanasia

15 Animal Disease Response Training Chemical Methods Carbon dioxide –Method of choice for swine and small ruminants –Concentrations above 25% Water-based foam –Rapid and humane –Floor-raised poultry Anesthetic Overdose –Animals closely associated with owners

16 Animal Disease Response Training Euthanasia Site Selection Facilitate with carcass removal process Located on level ground –Animal breaks loose –Allow heavy equipment Construction of portable confinement and road access

17 Animal Disease Response Training Assessing Needs Euthanasia decisions are based on several factors: –Location of animals to euthanize –Disease agent involved –Animal species involved –Number & size of animals

18 Animal Disease Response Training Assessing Needs Euthanasia decisions are based on several factors: –Training, experience, skill of personnel –Equipment and supplies available –Emotional impact of euthanasia procedure –Personnel safety –Public perception

19 Animal Disease Response Training Implementation of Euthanasia Protection of the public and responder –Adverse effect on consumers –PIO prepared to address public –Media requests through JIC –Law enforcement reroute traffic Administering euthanasia –Proper training for personnel –Very physically demanding –Local assistance such as slaughterhouse

20 Animal Disease Response Training Concluding Euthanasia May last hours or several days Euthanasia team heavily contaminated Extensive cleaning and disinfecting for team, equipment, and premises

21 Animal Disease Response Training Introduction to Animal Disposal Occurs simultaneously with euthanasia using five common steps 1.Select appropriate disposal method 2.Assess and request resources 3.Site for disposal 4.Implement disposal 5.Secure the site

22 Animal Disease Response Training Common Disposal Methods Burial onsite is preferred method of disposal Trench –More expeditious and inexpensive Landfill –Concern for public opposition –Arrangements made in advance Mass burial sites –Systems to collect gas and leachate Recommended to lance the stomachs of ruminants allowing gases to escape before burial

23 Animal Disease Response Training Common Disposal Methods Composting –Requires abundant oxygen –Deactivates disease from temperature and pH –Requires well drained area away from water source –Security from scavenger species –Downwind of residences Incineration –Open air burning –Air-curtain incineration

24 Animal Disease Response Training Other Disposal Methods Rendering –Transportation –Capacity –Cleaning and Disinfection Methane digestion –Dairy farms –Co-generation facilities Rendering least used option due to capacity and transportation issues

25 Animal Disease Response Training Site Selection Burial site selected using GIS and soil surveys Maps identify three typical zones –Exclusion zone –Cautionary or limited zones –Acceptable zones

26 Animal Disease Response Training Assess and Request Disposal Resources Information needed to dispatch Disposal Team –Number and size of animals –Carcass location and disposal site location –Inventory of on-farm equipment available to assist –Estimate of heavy equipment operators needed –Obstacles to ingress and egress on site

27 Animal Disease Response Training Implementing Disposal Choose method using best industry, scientific, and regulatory practices Plans should identify method long before need arises Disposal site security –People and animal scavengers Environmental impact and continuous monitoring after incident

28 Animal Disease Response Training Summary Euthanasia and disposal is critical to reduce spread of disease Animal restraint and depopulation must be humane Personal safety is paramount in all activities Disposal occurs simultaneously with euthanasia Disposal options will depend upon characteristics of the premises and regulatory requirements
