Within the Canadian Food Inspection Agency and Agriculture and Agri-Food Canada the International Affairs Branch engaged with trading partners that accept Canadian pork products and byproducts and looked at having them accept Canada's zoning arrangements.In general, when a zone is placed, it is a ten-kilometer radius around an infected farm or premise and, when we go to a trading partner, what we're saying to them is that we are confident in the epidemiology of the outbreak thus far, that it's not outside of that ten-kilometer area or however large it needs to be comfortable with it being contained.
But outside of that zone would be considered disease free.
Dr. Lundquist says Canada has zoning arrangements in place the United States, the European Union, Singapore and Vietnam representing just under 40 percent of our pork export market and we continue to pursue arrangements with other countries including Japan, the United Kingdom, Mexico, the Philippines, South Korea, Chile and Peru.
