2012년 8월 3일 미 농무부(USDA)가 캘리포니아 광우병 최종역학조사보고서를 발표했습니다.
예상대로 충분한 과학적 근거도 제시하지 못하고 광우병에 걸린 홀스타인 젖소는 오염된 사료와 무관하다고 발표했습니다. (비정형 광우병의 원인이 사료와 관련이 있는지, 없는지는 아직까지 과학적으로 충분히 규명되지 못한 상황입니다)
캘리포니아 광우병 소를 안락사시켜 렌더링 공장에 팔아넘겼고… 렌더링 공장에서 그야말로 우연하게 무작위추출(렌덤 샘플링)에 의해 광우병 검사가 실시되었음에도… 미국의 광우병 위험관리체계는 전혀 문제가 없다고 발표했습니다.
미국 정부의 발표는 캘리포니아 광우병 소가 도축되어 인간의 식품체계로 유입되지 않았다는 점을 강조하고 있습니다. 이것은 당연한 내용입니다. 세상에 어떤 미친 정부가 광우병 검사를 통해 양성이 확인된 소를 도축하여 인간의 식품체계로 유입되도록 그냥 손 놓고 있겠습니까?
문제는 미국에서 1년에 4천만 마리가 넘는 소를 도축하고 있고… 그 중에서 광우병 검사를 4만 마리만 하고 있는데… 광우병에 걸렸으나 광우병 검사를 받지 않고 인간의 식품체계로 유입된 사례가 발생할 가능성이 중요한 것입니다. 왜냐하면 광우병은 사후 부검을 통한 검사를 통해서만 진단을 할 수 있기 때문입니다. 또한 비정형 광우병, 무증상 광우병의 경우는 정밀한 광우병 검사를 실시하지 않으면 감염여부를 전혀 확인할 수 없습니다.
미국 정부는 캘리포니아 광우병 소가 낳은 새끼 중 생존해 있는 1마리만을 안락사시켜 광우병 검사를 실시했으며… 광우병 소의 birth cohorts는 생존해 있는 소가 없어서 광우병 검사를 실시하지 못했습니다.
해당 농장에 사료를 공급했던 회사는 12곳인데… 그 중 1곳은 폐업을 한 관계로 조사를 하지 못했으며 11곳을 조사했습니다.
미국은 광우병 위험물질(SRM) 중에서 30개월 이상 소의 뇌와 척수만을 육골분 사료의 원료로 사용하는 것을 금지하고 있을 뿐입니다. 나머지 광우병 위험물질 부위는 사료의 원료로 여전히 사용되고 있으며… 30개월 미만인 경우엔 뇌와 척수도 사료의 원료로 사용할 수 있습니다. 문제는 렌더링업자들이 소의 연령이 30개월 미만인지 그 이상인지를 구분할 수 있는 객관적 지표를 갖추지 못했다는 점입니다.
이런 상황에 눈 감은 미국 정부의 최종 역학조사보고서는 “눈 가리고 아웅”하는 요식행위에 불과할 뿐입니다.

Update from APHIS Regarding Release of the Final Report on the BSE Epidemiological Investigation
출처 : http://www.aphis.usda.gov/newsroom/2012/08/bse_update.shtml
Today, USDA is releasing its final report on the epidemiological investigation of a dairy cow from California that tested positive for bovine spongiform encephalopathy (BSE) in April 2012. This epidemiological report is the result of months of close coordination with the U.S. Food and Drug Administration (FDA), the California Department of Food and Agriculture (CDFA), local officials, and the associated dairy and rendering facility.
In accordance with World Organization for Animal Health guidance, USDA conducted a thorough epidemiological investigation following the BSE detection. This included on-the-ground investigations and records review from the rendering facility, the index farm, and associated premises, as well as traceback for progeny and birth cohorts of the index cow.
The results of this thorough investigation confirmed that at no time was the U.S. food supply or human health at risk, and that the United States’ longstanding system of interlocking safeguards against BSE continues to be effective.
This case was found in an animal that was sampled for the disease at a rendering facility in central California. This animal was never presented for slaughter for human consumption, so at no time presented a risk to the food supply, or to human health in the United States.
The index animal was a 10 year 7 month-old Holstein cow from a central California dairy. The animal was humanely euthanized after it developed lameness and became recumbent, and was sampled by a renderer contracted to collect samples as part of USDA’s ongoing BSE surveillance. Results from immunohistochemistry and Western blot tests at USDA’s National Veterinary Services Laboratories (NVSL) confirmed the animal positive for atypical BSE. Samples were also sent to the World Organization for Animal Health (OIE) reference laboratories in Canada and England. The laboratories confirmed that the index cow was positive for atypical (L-type) BSE.
As a result of on-the-ground investigation and records review, USDA and CDFA identified only one live offspring of the cow, which was humanely euthanized and found to be negative for BSE. No birth cohorts of the index animal were found alive.
The carcass of the index animal (along with approximately 90 other carcasses being held at the renderer’s transfer station), were disposed of in a landfill in accordance with all Federal, State and local regulations. The carcass of the index animal did not enter the human or animal food chain.
In conjunction with USDA’s investigation, FDA and CDFA conducted an extensive feed investigation. Twelve feed suppliers were identified to the index premises; one of which was no longer in business. The remaining 11 were found to be in compliance with FDA and CDFA regulations and requirements. FDA has released a full report on the feed investigation. It is available at www.fda.gov.
The United States has a longstanding system of three interlocking safeguards against BSE that protects human and animal health, the most important of which is the removal of specified risk materials – or the parts of an animal that would contain the BSE agent should an animal have the disease – from all animals presented for slaughter in the United States. The second safeguard is a strong feed ban that protects cattle from the disease. The third safeguard—which led to this detection— is our ongoing BSE surveillance program that allows USDA to detect the disease if it exists at very low levels in the U.S. cattle population and provides assurances to consumers and our international trading partners that the interlocking system of safeguards in place to prevent BSE are working.
