WATER RESEARCH COMPENDIUM 2009-2014 lists PRIONS eight times as an EMERGING CONTAMINANT of concern in sewage sludge “biosolids”, water and manure.

But the US Environmental Protection Agency (EPA), and the waste industry including SYNAGRO, promote Class A sludge “biosolids” compost for spreading on home vegetable gardens, and parks, playgrounds, and ballfields where children with their hand-to-mouth behavior, will be playing.  Even though they know Class A sludge “biosolids” contains infectious prions,  the EPA/waste industry nevertheless promotes this contaminated waste as being “pathogen free” or “sterile”.


Postings to Composting Council discussion group in 2006 on issue of infectious human and animal prions in both Class A and Class B sewage sludge biosolids, with particular regard to the fact that EPA pathogen reduction measures under Part 503 do NOT inactivate prions …

Email to US EPA and WEF – human and animal prions in Class A sewage sludge biosolids compost which is promoted for home use as pathogen free:

  • “PRIONS” ARE PATHOGENS — The Prion Diseases
  • Prions in intestines and feces
  • “Human prions in public sewers, autopsies, etc.”
  • “Human prions in public sewers, embalmers, funeral directors, etc. “

Persistence of Pathogenic Prion Protein during Simulated Wastewater Treatment Processes

Transmissible spongiform encephalopathies (TSEs, prion diseases) are a class of fatal neurodegenerative diseases affecting a variety of mammalian species including humans. A misfolded form of the prion protein (PrPTSE) is the major, if not sole, component of the infectious agent. Prions are highly resistant to degradation and to many disinfection procedures suggesting that, if prions enter wastewater treatment systems through sewers and/or septic systems (e.g., from slaughterhouses, necropsy laboratories, rural meat processors, private game dressing) or through leachate from landfills that have received TSE-contaminated material, prions could survive conventional wastewater treatment.

Inflammation and prions in Urine

Adriano Aguzzi of the University Hospital of Zurich: “Further research by the team showed that, if inflammation is induced in any excretory organ of the body, prions are excreted in whateversubstance the organ excretes. ”

Transmission and Detection of Prions in Feces

Oral exposure to prion-tainted blood, urine, saliva, and feces has been suggested as the mode of transmission of CWD and scrapie among herbivores susceptible to these prion diseases.
