It is not a bacteria, but a protein, sometimes secreted by bacteria, but found in the excreta of any creature consuming animal proteins. It becomes concentrated at up to 600 times normal background levels in sewer sludge. And as noted, it is not broken down by normal composting, even at commercial treatment levels.
There is little evidence yet on this front; the science is new, and so are the experiments. It may be years before we start to see good solid data.
But there is VERY compelling evidence that there are serious issues here, so why should we continue to use the general populace as guinea pigs? Europe and Canada have put the Precautionary Principle into law to protect their populations; we continue to labor under laws designed to help out corporations. If this stuff is so harmless, prove it.
Instead we, the unfunded and unprotected populace are forced to prove it harmful while unknown numbers of us are subjected to the terrifying prospect of losing the very core of our being, our memories. Our families are subjected to watching a wasting more insidious than any physical degeneration. There are several specific prioinic poisoning incidents that point clearly to the possibility of prionic brain plaques being a causal agent for Alzheimers, yet the damage continues until you can "prove it in a court of law."
Is this any way to run a country? Tobacco, DDT, BisA; why must we continually subject ourselves to a toxic stew at the whim of corporate powers more concerned with bottom line than customer health? Why shouldn't they have to prove their product safe instead of the other way around?
