EPA and University of Wisconsin research has found that sewage sludge may also contain infectious human and animal prions which can cause transmissible spongiform encephalopathies such as Alzheimers, Creutzfeldt Jakob Disease, Mad Cow Disease, Chronic Wasting Disease, Scrapie, etc.

Sewage sludge fertilizer should not be used in public parks, ballfields, playgrounds, and home flower and vegetable gardens. Peer reviewed scientific research has found that plants, including vegetables can take up sludge pollutants. Children eat dirt, and family pets can track the sludge into homes on their feet and fur. Many gardeners and other victims have been sickened by use of or contact with Class A sludge biosolids “fertilizer”.

Your recommendation to use sewage sludge biosolids to “fertilize” organic gardens is truly bizarre, since US Dept. of Agriculture organic rules specifically PROHIBIT the use of sewage sludge, genetic engineering, pesticides, drugs, hormones, and antibiotics in organic farming. http://www.organicconsumers.org/Organic/averycummins.cfm
