The risk is enormous. Prion disease is always deadly. There is no cure. There is no way to neutralize deadly prions in sewage. Prions migrate, mutate and multiply. People with Creutzfeldt Jakobs disease, Alzheimers and other prion diseases are infected with deadly prions. They proceed to contaminate their environment with their bodily fluids (urine, feces, saliva, blood, etc). If just one person with prion disease has used your sewage system, the system is permanently contaminated. Everything discharged from that plant is contaminated. Watersheds that receive the biosolids are contaminated. Every time that it rains on the biosolds, water runoff can spread prions to groundwater. Rain and irrigation can spread prions via surface water runoff--into creeks, ponds, streams, lakes, rivers and oceans. Cattle and other animals that graze on land with biosolids will uptake soil as they graze, which exposes them to prion disease (better known as Mad Cow disease). Therefore, biosolids threaten food and water supplies. See my posts on prion diseases at www.GaryChandler.com (go into the archives and find "Pandora's Lunchbox" for citations and further detail.
