Luckily for those of us in the cattle business, this seems to have slipped under the radar screen of the fear-mongering news types for now. Please note that it is my understanding that this is not a new case! Also note that this carcass never entered the food supply!

The only reason that I chose to post it is an effort to prevent the hysterical hand-wringing that some people are prone to with any mention of BSE. Much better for us to be aware of what is happening and be able to discuss this with consumers than to let the media handle it. This should also be factored into any marketing that is done today or early next week.




STATEMENT BY DR. JOHN CLIFFORD REGARDING FURTHER ANALYSIS OF BSE INCONCLUSIVE TEST RESULTS

June 10, 2005

"Since the USDA enhanced surveillance program for BSE began in June 2004, more than 375,000 animals from the targeted cattle population have been tested for BSE using a rapid test. Three of these animals tested inconclusive and were subsequently subjected to immunohistochemistry, or IHC, testing. The IHC is an internationally recognized confirmatory test for BSE. All three inconclusive samples tested negative using IHC.

"Earlier this week, USDA's Office of the Inspector General (OIG), which has been partnering with the Animal and Plant Health Inspection Service, the Food Safety and Inspection Service, and the Agricultural Research Service by impartially reviewing BSE-related activities and making recommendations for improvement, recommended that all three of these samples be subjected to a second internationally recognized confirmatory test, the OIE-recognized SAF immunoblot test, often referred to as the Western blot test. We received final results a short time ago. Of the three samples, two were negative, but the third came back reactive.

"Because of the conflicting results on the IHC and Western blot tests, a sample from this animal will be sent to the OIE-recognized reference laboratory for BSE in Weybridge, England. USDA will also be conducting further testing, which will take several days to complete.

"Regardless of the outcome, it is critical to note that USDA has in place a sound system of interlocking safeguards to protect human and animal health from BSE-including, most significantly, a ban on specified risk materials from the human food supply. In the case of this animal, it was a non-ambulatory (downer) animal and as such was banned from the food supply. It was processed at a facility that handles only animals unsuitable for human consumption, and the carcass was incinerated.

"USDA's enhanced surveillance program is designed to provide information about the level of prevalence of BSE in the United States. Since the inception of this program, we have fully anticipated the possibility that additional cases of BSE would be found. And, in fact, we are extremely gratified that to date, more than 375,000 animals have been tested for the disease and, with the exception of the conflicting results we have received on this one animal, all have ultimately proven to be negative for the disease.

"USDA is committed to ensuring that our BSE program is the best that it can be, keeping pace with science and international guidelines, and to considering recommendations made by OIG and others in this regard. We are committed to ensuring that we have the right protocols in place-ones that are solidly grounded in science and consistently followed. After we receive additional test results on this animal, we will determine what further steps need to be taken and what changes, if any, are warranted in our surveillance program."
 
Texan, This is probably worse news than a new found case in the US. It might call into question the entire testing protocol of the USDA for BSE.
The USDA were highly questioned when they announced the approval of the Bio-Rad test last year because of false positive history of the test. The Prionic's Check Western test was the newest most accurate test available at the time. It has the ability to detect sub-clinical cases (where prions are in the body -but not accumulated in the brain as of yet) and the "gold standard" IHC (immunohistochemistry) was still being used by the USDA and cannot detect subclinical cases.
When the press gets hold of "How many cases could have slipped through the cracks?" we could be in for a dry spell as far as exporting beef.
 
I,m pretty sure this won,t retest positive.It will likely be inconclusive.

even if it does test positive R-calf has all the answers.
 
Now now frenchie, lets try not to be so negative. Who knows what a positive test result will do for the relations between canada & US.

I agree though should the test result be positive it will be interesting to see the reaction of R calf and how they try to work it to their advantage.

Also just asking have they traced down the origin of the cow? I have not heard.
