After the border between the US and Canada closed in response to an Alberta case of bovine spongiform encephalopathy, OMAFRA is examining the economic impact if one of the major borders closed again. After, they will attempt to create a strategy to mitigate the effects. The first part is prevention, and biosecurity and traceability can help accomplish this. A communication strategy should be developed for industry, government, international, and public communication in the event of a closure. The strategy will also address managing the surplus of product and live animals on farm and at rendering facilities, and create support programs for individuals and businesses.
