[USCC] Compost made with biosolids

Thu May 22 12:33:26 CDT 2008

I suggest that before panic sets in regarding CJD, etc., that we consult the
research on this topic.  Newspaper articles are NOT nor never have been
research.

If this premise is true Wastewater operators and sewer line repair folks
aught to be just ate up with CJD.

Next, how would propose we dispose of this material safely?

Promoting Class A sewage sludge "biosolids" as an unregulated pathogen free
fertilizer is a fraud on the public.

The US Environmental Protection Agency (EPA) and waste industry know  there
is no sewage pathogen reduction method which deactivates human and/or animal
prions.     To the contrary, research confirms that  wastewater treatment
reconcentrates the infectious prions in the sewage sludge.

Human victims of Creutzfeldt Jakob Disease (CJD) are  shedding infectious
prions into public sewers, to end up in both Class B sewage sludge and Class
A sludge compost.   Between 2 and 25% of the over 4.5 million cases of
Alzheimer's Disease and senile dementia victims in the US are actually
infected with sporadic CJD.  (Manuelidis, et al, 1989; Boller, et al, 1989,
1995; Harrison, 1991; Teixeira, 1995;  Warren, et al, 2005) creating the
reality that many thousands of sCJD victims are shedding infectious prions
into public sewers.

Prions have been found in the blood and urine of CJD victims.  (Gabizon, et
al, 2001; Reichl, et al 2002) .   Undertakers and medical facilities
routinely discharge CJD infected blood and body fluids into public sewers.
(Yale; UC Davis, CDC)

  Prions can cross the intestinal barrier by riding piggyback on ferritin, a
protein normally absorbed by the intestine.  Because ferritin shares
considerable homology across species, these data suggest that
PrPSc-associated proteins, in particular ferritin, may facilitate PrPSc
uptake in the intestine from distant species, leading to a carrier state in
humans.  (Singh, et al 2004)

" . . . enteric infection at early as well as later stages of (CJD) disease,
and regardless of the route of agent entry, implicates potential
environmental spread by fecal matter."  (Radebold, et al 2001)

Class B sewage sludge "biosolids" is expected to be pathogenic.    EPA
allows land applied sludge "biosolids" to contain  fecal coliform up to 2
million CFU/gram.  But the EPA and waste industry promote the use of
"pathogen-free" Class A sludge "biosolids" compost on playgrounds, ball
fields, public parks, and home flower and vegetable gardens 

.       "Pathogen free" is clearly not the case when the Class A sludge
compost can contain infectious human and animal prions.    Not only are
livestock and wildlife at risk from ingesting prion infected soil and
sludge,  but humans, and particularly children,  are especially at risk
because their hand to mouth behavior results in the ingestion of dirt
(Robischon, 1971; LaGoy, 1987; Binder, et al 1986; Gerba, et al 2002 ; CDC,
Callahan,  2004).

The EPA guidelines and disclosures on pathogens in Class A sludge
"biosolids" compost need to be revisited.   And suggesting this
toxic/pathogenic Class A waste be totally unregulated is reckless as
research piles up documenting the amplification and long survival of
infectious human and animal prions in soil.  (CWD prions in soil amplified
700 times, Pedersen, Aiken, 2007)
