Charlie and Lee;
I find it disturbing that Canada is not following known information on infected BSE animals, that the normal BSE infection shows up between 3-5 years of age, this is not a disease of just older cows, but can appear in cattle at 24 months!
Why are we not proposing safegaurds that err on the side of saftey?
The following FAO recomendation exists;
"- Specified risk materials (brains, eyes, tonsils, spinal cord, etc.) should be removed from all beef and sheep carcasses over 12 and 6 months respectively"
Why are we going to make 30 months the standard, when clearly it should be 12 months for beef and 6 months for sheep?
The folowing articles are telling:
BSE - Bovine Spongiform Encephalopathy
http://www.prionics.ch/prionics-e.htm
BSE (Bovine Spongiform Encephalopathy) was first described in the UK in 1985. In 1996, new scientific findings indicated that BSE is transmissible to man and causes a variant of CJD.
After the infection of cattle with BSE, 3-6 years pass on average before clinical symptoms (such as the decline in milk production, shaking and timidness) develop. This incubation time can vary widely, with a span of from from 20 months (youngest) to more than 15 years. As a result of this incubation time, products from infected but not visibly ill animals end up in the human food chain.
In a first phase after infection, the infectivity of an affected animal is at a very low level. Officials therefore assume that BSE-infected animals do not pose a health risk to humans in this phase. Nevertheless, it should be stated here that the possibility of potential risks can not be completely ruled out.
In a second phase, before the occurrence of clinical symptoms, the infectious agent is found to be highly concentrated especially in the brain and in the spinal cord. It is this phase which represents the main risk factor for public health: an animal in this phase of infection poses the same risk to the consumer as a visibly ill animal, but is not detected due to the lack of signs of disease. The duration of the second phase is thought to be at least 6 months.
In a third phase clinical symptoms occur followed by death. The age of animals in the third phase of the disease ranges from 20 months to 16 years. The average and most frequent age is between 3 to 5 years.

Andrew Speedy from the Animal Production and Health Division of the Food and Agriculture Organisation (FAO) of the United Nations anounced today in a press release that all countries should continue to check for the disease and apply precautionary measures. "Even countries which have not found any cases of BSE should now consider adopting mor stringent measures" Mr. Speedy said.
Countries should apply the following measures:
- Besides passive surveillance and testing of all animals showing neurological symptoms, active surveillance should be carried out, including: all cows which are killed because of disease or accident; all emergency slaughtered cows; and a random sample of all cows during routine slaughter.
- A national risk assessment should be conducted for the presence of BSE, considering imports of feed and cattle and the efficiency of the rendering and feed industries.
- Specified risk materials (brains, eyes, tonsils, spinal cord, etc.) should be removed from all beef and sheep carcasses over 12 and 6 months respectively.
- Standards of rendering need to be improved with the correct temperature, pressure and time of processing (133 degrees, 3 bar, 20 minutes).
- All cross-contamination of rendered products and in animal feed manufacture must be avoided. There are risks of cross-contamination if feed for poultry and pigs or pet food is in contact with feed for cows.
- Where this cannot be achieved, the use of meat and bone meal in animal feeds should be banned altogether.
- Cows found with BSE must be killed; all direct offspring of cows with BSE should be slaughtered, as well as all animals born in the same year and the same herd as the animal with BSE; in all these cases, the carcass must be incinerated.
- Effective national identification and recording should be implemented to ensure that animals can be traced back to source.
Open trade depends on assurance that the product is safe and this can only be achieved by undertaking the national risk assessment, active surveillance and implementation of all recommended measures, Mr. Speedy said. "It is not so much whether there have been isolated cases of BSE found by animal testing, but rather whether the exporting country can provide assurance that the system is in place to keep infective material out of the food chain."
If I were the US and Japan, I would not be pleased with Canada, we have not come clean yet... IMHO!
