At this time, there is no irrefutable proof that BSE tainted meat causes vCJD. However, I have posted (probably hundreds by now) of articles which high-light spongiform diseases/symptoms after contamination with various metals, inlcuding lead.
The University of Saskatchewan has several researchers there who have received funding to look at the role of metals in the brain, eg.

CFI Awards $22 Million for Major New U of S Research Facilities
The four U of S projects include:
• BioXAS: Life Science Beamline for X-ray Absorption Spectroscopy: Led by U of S Canada Research Chair Graham George, this $20.6-million suite of two beamlines at the Canadian Light Source will be used to study biological and health-related functions of metals in diseases such as Alzheimer's, as environmental toxins, in metal-containing drugs, and as essential constituents of living systems.
• National Agricultural Industrial Hygiene Laboratory: Led by U of S researcher Jim Dosman at the Canadian Centre for Health and Safety in Agriculture, this $14.5-million initiative will provide tools to study the health effects in workers and others exposed to the risks of modern agricultural production and related rural activities.
• Feed Technology Research Facility: Led by U of S researcher Bernard Laarveld, this $12.6-million initiative will explore challenges related to the burgeoning bioproducts industry, such as how to make high-value animal feed products from low-value crops and by-products created by biofuel plants.
• Aquatic Toxicology Research Facility: Under the leadership of U of S environmental toxicologist Karsten Liber, this $7-million unique-in-Canada initiative will provide the tools to detect, monitor, and evaluate toxic pollution in our lakes, rivers, and other aquatic ecosystems. This will provide crucial information for policy, regulation, and environmental remediation.
The Canada Foundation for Innovation (CFI) is an independent corporation created by the Government of Canada to fund research infrastructure. Its mandate is to strengthen capacity among Canadian universities, colleges, research hospitals, and non-profit research institutions to carry out world-class research and technology development that benefits Canadians. More information is available at www.innovation.ca.
Dr. Graham George and others are working with the Canadian Light Synchrotron. In an earlier news release from 2004, it is noted:

In our normal everyday lives, we are exposed to an incredibly complex chemical soup.
Many of these compounds contain metal atoms which, once inside us, can either fulfill roles that are essential to health or act as poisons, sometimes with deadly consequences.
• Specifically,
Graham George will study mercury, a toxic metal that is a health concern in Canada and worldwide. Exposure sources are numerous, and include methylmercury compounds in predatory marine fish and "silver" fillings in teeth. Mercury compounds (such as methyl mercury) are
severely neurotoxic in that they can damage the human nervous system, but the mechanism of neurotoxicity remains largely unknown.
• George will use the new Canadian Light Source synchrotron to study mercury's molecular form, how it is modified in foods and in tissues, and
how it interacts with other elements such as selenium. This will eventually allow the use of advanced techniques to design highly specific drugs - called
custom chelators - that could be capable of specifically binding and removing mercury from tissues.
You wouldn't think that there is a scientist on this planet that would deny the relevance of this work. However, the media has reported "news bits" from various researchers in the past and one such bite actually stated, "mercury is good for you, it makes you more creative".
Our cattle industry and health industry must tackle the BSE problem head on - no matter what the fallout. Keeping in mind, that we need to question all science, and verify results. MBM feeding trials did not transmit BSE. Only specially designed laboratory tests that homogenized the brain tissue, were successful at limited transmission of an "unidentified agent."
The cattle industry should demand that the health of our cattle be an indicator for the health of the environment. If our cows are sick, so is the environment and we all breath the same air, drink the same water and consume vegetation grown from the soil. Once the consumer understands that these metal contaminants, chemical contaminants etc are causing these diseases (or at the very least, causing susceptibility to disease for those that can't yet see the direct connection) then they will demand that we clean up the sources of the environmental toxins.
When my neighbor wanted to vaccinate his cattle with two different shots, one had mercury in it the other aluminum, he was fortunate enough to have circumstances prevent this from happening (at least on the same day).
Alzheimer's disease was discovered in 1906, again in America, where dentists used mercury-laden amalgams to fill cavities (dentists in Europe largely avoided them). Today, more than 4 million Americans now have Alzheimer's disease. It afflicts half of people over the age of 85 and 20 percent aged 75 to 84.
The first symptoms of this disease are difficulty concentrating and variable degrees of memory loss, leading ultimately to devastating mental deterioration. The brains of people with Alzheimer's disease shrink by 25 percent and have distinct pathologic hallmarks (neurofibillary tangles, amyloid plaques, and phosphorylation of tau protein). Brain cells grown in the laboratory develop the same three pathologic findings when exposed to nanomolar (3.6 × 10-10 molar) doses of mercury, an amount approximating that found in the brains of people who have a lot of amalgam fillings.
Dental amalgams are the main source of mercury in an adult's brain. An average-sized amalgam filling contains 750,000 micrograms of mercury and releases around 10 micrograms a day. Researchers put radiolabelled mercury amalgams in the teeth of sheep and determined where escaped mercury went with a scanner. They showed that mercury atoms exhaled through the nose travel up filaments of the olfactory nerve to the hippocampus, which controls memory, and to other critical areas in the brain. In another study, rats given the same concentration of mercury that people inhale from their amalgams develop the pathologic markers of Alzheimer's disease. People with Alzheimer's disease have mercury levels in their brains that are 2 to 3 times higher than that seen in normal people.
The mercury in flu vaccines also plays a role in this disease. One investigator has found that people who received the flu vaccine each year for 3 to 5 years had a ten-fold greater chance of developing Alzheimer's disease than people who had zero, 1, or 2 shots.
Another important factor with regard to mercury on the mind, which officials at the CDC, FDA and the professors in the IOM do not consider, is synergistic toxicity – mercury's enhanced effect when other poisons are present. A small dose of mercury that kills 1 in 100 rats and a dose of aluminum that will kill 1 in 100 rats, when combined have a striking effect: all the rats die. Doses of mercury that have a 1 percent mortality will have a 100 percent mortality rate if some aluminum is there. Vaccines contain aluminum.
