The only problem with this new  EPA research on prions in sewage sludge biosolids is that it fails
to consider HUMAN as well as animal prions in BOTH CLASS A and CLASS B sewage sludge . . . .
. Class A sewage sludge biosolids compost/"fertilizer"  (such as "Milorganite") which may contain
both infectious human and animal prions is sold by the bag to an unsuspecting public at WalMart,
Home Depot, nurseries, hardware stores, etc. it is spread on ballfields, playgrounds, and
homeowners are encouraged to spread it on their lawns and in their flower and vegetable
gardens . . . . kids eat dirt -- and "pica" kids eat LOTS of dirt !    And obviously, topdressing prion
infected Class B sewage sludge on grazing lands and dairy pastures puts both livestock and
cervids at risk of ingesting infectious prions . . . . . . .

Also, if anyone wants it,  I can share by computer my  30+ page word/doc  file on animal prions in
both Class A and Class B sewage sludge biosolids.    Prions may be  discharged to public sewers
via landfill leachate, abattoirs, taxidermy shops, vet labs and facilities, etc.      Two Risk
Assessments (Wisconsin and Stanfield & Gale) have found that the wastewater treatment process
reconcentrates the hydrophobic prions in the sewage sludge.    No existing sludge pathogen
reduction method inactivates the prions.  Prions can survive in soil for 3 to 6 years.    It is well
known that grazing livestock can ingest up to one kilogram of soil (and sludge) per day.     Thus
the prions in both Class A and Class B sewage sludge may be infectious and put humans,
livestock,cervids and possibly other species, at risk.   Researchers have said as little as one-half
a gram can be infectious.

Because the USDA and cattle and beef industry are terrified  of the economic losses should any  
USA cattle be diagnosed with BSE, (remember Oprah ? )  very little testing is being done in USA
and whistleblowers claim test results are being covered up . . . (Friedlander - http://sask.cbc.

SASKATOON – An allegation of a U.S. coverup of mad cow cases south of the border has been
generating debate and disbelief in Canada. )


However, In Japan, where all animals over 30 months are tested, they have recently uncovered
their 18th and 19th cases of bovine spongiform encephalopathy.

Week of 6-7-04 Biosolids Update (WORD)

From Water & Wastewater Products E-News, 6-4-04.   Researchers To Study Fate Of Prions In
Wastewater.  With funding from EPA, a group of University of Wisconsin-Madison researchers will
investigate what happens if infectious prion proteins -- considered the cause of chronic wasting
disease and mad cow disease -- enter wastewater treatment plants.
