Sewage treatment and composting do not inactivate human and animal prions in
sewage sludge "biosolids":
October 2, 2012
"The Environmental Protection Agency (EPA) and US Dept. of Agriculture, (USDA) fail to
warn public about infectious human and animal prions in sewage sludge biosolids
being spread on food crops and grazing lands - uptake of prions by plants - risks to
humans and animals "

EPA NATIONAL WATER RESEARCH COMPENDIUM 2009-2014 lists PRIONS eight times
as an EMERGING CONTAMINANT of concern in sewage sludge "biosolids" , water and manure:
“PRIONS” ARE PATHOGENS, 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":
PRIONS IN COMPOSTING
Postings of Helane Shields 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 . . . . .
"EPA recommends Class A sludge biosolids on home vegetable gardens. Class A
sludge is not pathogen free - it can contain E. Coli bacteria which survive thermal sludge
treatment - AND it contains infectious human and animal prions which are NOT inactivated by
any sewage/sludge treatment."
"Plants, vegetables, grasses, forages uptake sludge pollutants, pathogens and

Helane Shields 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. "
"Young prion disease victims - hunters, venison eaters and others - are they victims of the
Chronic Wasting Disease (CWD) epidemic which is spreading throughout the US?
See below for pdf
The following states and Canadian provinces are designated CWD positive: Alberta,
Colorado, Illinois, Kansas, Maryland, Michigan, Minnesota, Missouri, Nebraska, New
Mexico, New York, South Dakota, Utah, Virginia, West Virginia, Wisconsin,
Wyoming, Saskatchewan, Texas and CWD recently jumped the border into Iowa.
Alzheimers and Creutzfeldt Jakob Disease (CJD) are sister prion diseases in humans, just as
Mad Cow and Chronic Wasting Disease are in animals. "

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 whatever
substance 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
