That assessment would be made on variables such as strength and longevity of a ruminant-to-ruminant feed ban, slaughter and processing procedures, surveillance testing plans and the like. If the OIE were to decide to switch to such a standard, South Korea said it would be willing to reconsider its import standards, the Korea Herald reported. That would presumably mean an end to a 30-month rule on age and a ban on bones, since most bones are not considered to be specified risk materials. The latter is a key consideration for the United States, since two-thirds of shipments to South Korea prior to the BSE crisis were bone-in beef ribs, used in barbecue rib dishes, which are a national favorite.
