Given the tendency of the United States in general and R-Calf in particular to deny they have a BSE problem within their borders I thought it would be useful to revisit the recommendations and observations made by the International Review Panel that investigated the U.S. index case of BSE in December 2003. The panel was made up of the same scientists that investigated the Canadian case in May 2003 with the addition of one member.
Some key points and recommendations:
• The U.S. does not have an effective animal traceability system. Only 50% of the birth cohort were successfully identified.
• …it is probable that other infected animals have been imported from Canada and possibly from Europe. These animals have not been detected and therefore infective material has likely been rendered, fed to cattle, and amplified within the cattle population, so that cattle in the USA have also been indigenously infected.
• Having examined the information provided on trade in live cattle and livestock feed ingredients within the North American Free Trade Agreement (NAFTA), the subcommittee firmly believes that the first case of BSE in the United States can not be considered in isolation from the whole cattle production system in North America. The significance of this BSE case cannot be dismissed by considering it “an imported case”. The first BSE case detected in the USA, and the first “indigenous case” reported in Canada in 2003, must be recognized as both being BSE cases indigenous to North American.
• Unless aggressive surveillance proves the BSE risk in the USA to be minimal according to OIE standards, the subcommittee recommends that the SRM identified below be excluded from both the human food and animal feed chains.
• Brain and spinal cord of all cattle over 12 months of age
• Stull and vertebral column of cattle over 12 months of age
• Intestine-from pylorus to anus-from all cattle
• …that non-ambulatory cattle are more likely to be BSE infected than are healthy slaughter cattle and therefore may pose a greater risk to public and animal heatlh. The goals for measures related to these cattle must to (1) test them for surveillance purposes (2) prevent potentially infective tissues from entering the food and feed chains. Given their exclusion from supervise slaughter at inspected slaughterhouses, this important population may no longer be available for the BSE surveillance programme at these locations. Therefore it is imperative that the USDA take additional steps to assure that facilitated pathways exist for dead and non-ambulatory cattle to allow for collection of samples and proper disposal of carcasses.
Therefore the subcommittee recommends that the US should demonstrate leadership in trade matters by adopting import/export policy in accordance with international standards, and thus encourage the discontinuation of irrational trade barriers when countries identify their first case of BSE.
