The Disposal of Humanely Euthanized Birds and Other Potentially Contaminated Material from an Avian Influenza Infected Premises
The Canadian Food Inspection Agency (CFIA) requires all contaminated material (e.g. bird carcasses, manure/litter, leftover feed, and eggs (if applicable)) from the infected premises to be disposed of, or to be treated through a verified biological heat treatment process to inactivate the Avian Influenza virus. This process is achieved by creating compost windrows of the contaminated material inside the barn. CFIA monitors the windrows using temperature probes to confirm the materials have maintained a minimum time and temperature according to a hazard assessment. Once these conditions have been confirmed, the CFIA releases the material to the farmer for ongoing composting and ultimate disposal according to Ontario regulation O.Reg 106/09.
Though the material is not completely composted at this time, the AI virus is inactivated. The material is moved out of the barn to a selected site that meets a number of specified provincial setbacks where the secondary stage composting will occur. The material will continue to compost and heat treat for several weeks or months until all soft tissue is consumed and the material resembles topsoil.
Once the material is removed from the barns, the farmer is able to start the Cleaning and Disinfection (C&D) process of the barns and equipment to ensure there is no virus remaining. After C&D is completed, the premises will remain under quarantine for an additional 21 days.
At the end of the compost process, this material will be land applied to crop land in accordance with the provincial Nutrient Management Act.
