Markets that have closed their borders to Canadian beef after a case of bovine spongiform encephalopathy (BSE) was discovered account for just 3 percent of Canadian trade, Agriculture Minister Gerry Ritz said on Tuesday.

South Korea, Taiwan, Peru and Belarus have imposed trade restrictions on Canadian beef and beef products after Canada confirmed a case of BSE on Feb. 11. Indonesia banned non-edible byproducts from Canada.

"While they have imposed temporary restrictions, these markets, while important, represent ... some 3 percent of our overall trade," Ritz told legislators in the House of Commons.
