EPA fact sheet: Composting for Biosolids Management "Composting is not a sterilization process and a properly composted product maintains an active population of beneficial microorganisms that compete against the pathogenic members." http://deadlydeceit.com/Composting_biosolids.html
EPA study -- Occurrence of Pathogens in Distribution and Marketing Municipal Sludges "Although the use of sludge as a soil amendment is attractive, it is not without potential health risks. Toxic chemicals, including heavy metals and industrial organics, may enter the food chain and present long-term health risks." www.deadlydeceit.com/D_M_sludge.html
Toxic Organic sludge Dust is Not Good for You, Deaths doubled in 15 years --1980/1995 The year 1993 was not a good year for science, the law or public health. It was especially bad for farmers and the general public who depend on science and the law for protection from pollution. In 1993 the Water Environment Federation (WEF) documented that toxic organic sludge dust is a fire and explosive hazard very similar to grain dust. www.deadlydeceit.com/NSA-139
Before EPA released its sham of a regulation in 1993, the Australian government issued its "Statement of Principles concerning EXTRINSIC ALLERGIC ALVEOLITIS in the Veterans Entitlements Act" 1986. The government recognized that working with sewage sludge was a very dangerous occupational risk. www.rma.gov.au/SOP/97/057.pdf

"It is clear that composting causes serious health-related problems for compost workers including an excess of nasal, ear, and skin infections, burning eyes and skin irritation, increased fungal colonies, and higher white blood cell counts and hemolytic complement." "It is reasonable to assume that surrounding communities (exposed to the facility 24 hours a day, rather than the 8- hour work day) are also adversely affected, and anecdotal evidence indicates that may be the case." (p. 1) Both urban and rural communities across the country are reporting illnesses associated by their nearness to a composting facility. To mention just a few: Almaden, California in the West, Islip Township and South Bronx in New York in the East, and Franklin, Kentucky in the South. www.deadlydeceit.com/DD1.html
ANTIGENS AND ALLERGENS are a major concern for women and the elderly living near sludge disposal sites and for people who are exposed by using sewage sludge on their lawn and garden. Contaminated dust may collect in their homes causing Organic Toxic Dust syndrome, which may lead to pulmonary fibrosis. www.deadlydeceit.com/Bioaersols.htlm

A High-Level Disinfection Standard for Land-Applied Sewage Sludges (Biosolids) The potential for pathogen regrowth is the downside to sewage sludge being rich innutrients that promote the growth of bacteria and fungi.Exotoxins;"proteins and peptides secreted into the surrounding environment by growing cells",are produced by both gram-negative and gram-positive bacteria. They are usually the most toxic of the two general types of bacterial toxins. Because they can retain their toxicity at extremely high dilutions, some exotoxins, including staphylococcal enterotoxins and shigatoxin, are used as biological warfare agents. Traces of endotoxins in food and water can cause headaches, fever, fatigue, and severe gastrointestinal symptoms; however, their primary target is the lungs. In addition to the former symptoms, inhaling endotoxin- contaminated dusts can cause acute airflow obstruction, shock, and even death. www.ehp.niehs.nih.gov/members/2003/6207/6207.pdf

"Pathogen Destruction and Biosolids Composting" in Biocycle of June of 1996, "There is some evidence that coliforms and Salmonella sp. can survive prolonged exposure to temperatures of 55 C." Droffner and Brinton found that it took 56 days and 90 days for the densities of Salmonella sp. and E. Coli, respectively, to decline below the detection limit...These investigators also "cite evidence of mutant strains of E. coli and Salmonella sp. resistant to thermal environments in composting." (p. 68)
Although the vegetative cell of bacteria is usually killed by heat and disinfectant, the endospore is resistant to agents that kill the vegetative cell (heating, drying, freezing, chemicals, and radiation). "Nester, Roberts, Pearsall and McCarthy (1978) in their text Microbiology point out the threat that endospores present."
Linne and Ringsrud (1979) in their text Basic Techniques for the Medical Laboratory also point out how spores, as highly resistant forms of bacteria, pose a great problem in sterilization. They state that certain spores have been known to survive 16 hours of boiling. (p. 452)
Viable but non-culturable states A phenomena commonly known as viable but non-culturable state has been described for many bacteria including Campylobacter, E. coli, Salmonella enteritidis, Vibrio cholerae,Vibrio spp., and Legionella pneumophila (Rollins and Colwell, 1986; Chowdhury et al.,1994; Roszak, Grimes, & Colwell, 1984; Oliver et al., 1995) . The bacteria are still viable (exhibit low levels of metabolic activity) but fail to develop colonies on most traditionalsolid culture medium. Moreover, pathogens in this viable but non-culturable state have demonstrated the ability to return to an active potentially disease causing state (Colwell etal., 1985) www.deadlydeceit.com/SludgeScience.html
Soil and human health: a review Soil can affect human health in several ways leading either to specific diseases or to more general ill health. Some illnesses are caused by people's eating soil (geophagia), or by their inhaling it which can lead to malignancy if the soil contains asbestiform minerals; pathogens in the soil can lead to tetanus and infestations of hookworm, and particles may enter the body through abrasions and cause a form of elephantiasis.

The toxicities of many metals, such as mercury and lead, are known to man since the dawn of civilization. Organic compounds of some heavy metals are known to have a particular toxic impact on the central nervous system. Organomercury, particularly alkyl-mercuric compounds (e.g. methylmercury), has a selective effect on the granule cells of the cerebellum, the nerve cells of the calcarine cortex, and the sensory neurons in the dorsal root ganglia.

Neurotoxicity from Municipal Sewage Sludge By Raymond Singer, Ph.D.October, 1999 Based on results of the Neurotoxicity Screening Survey, symptoms consistent with neurotoxicity were found in all who completed the test. The two children born and raised on the farm have been classified by their schools as mildly retarded and having attention-deficit disorders, although there was no family history of these illnesses www.expertlaw.com/library/toxicology/sewage_sludge.html
"Airborne Irritant Contact Dermatitis due to Sewage "Sludge" in the Journal of Occupational Medicine, November 1981, 23, (11) p. 771-4 reported how an airborne irritant in sewage sludge caused an outbreak of cases of dermatitis among incinerator workers employed in a sewage treatment facility.
"Neurotoxic Effects of Solvent Exposure on Sewage Treatment Workers" in the Archives of Environmental Health, July/August, 1988, 43, (4), pp. 263-68. They found after examining nineteen STWs (Sewage Treatment Workers) exposed to industrial sewage that contained benzene, toluene, and other organic solvents at a primary sewage treatment plant in New York City (Plant A). "that fourteen (74%) complained of central nervous system (CNS) symptoms consistent with solvent exposure, including lightheadedness, fatigue, increased sleep requirement, and headache."
"Work Related Symptoms Among Sewage Workers" in the British Journal of Industrial Medicine in August 1983, revealed that a higher proportion of employees at sewage treatment plants reported skin disorders, diarrhea, and other gastrointestinal symptoms than the control group. The results of a clinical investigation that was made among workers in a sewage treatment plant in Switzerland with similar aged workers in a control group who were not exposed to sewage showed that in about half of the exposed workers there were acute incidences of fever and eye symptoms.

Cyanobacterial toxins: occurrence, modes of action, health effects and exposure routes. Codd GA, Ward CJ, Bell SG. Department of Biological Sciences, University of Dundee, UK.
Cyanobacterial toxins are produced by terrestrial- fresh-, brackish- and sea-water cyanobacteria of cosmopolitan occurrence. These toxins present acute and chronic hazards to human and animal health and are responsible for isolated, sporadic animal fatalities (mammals, fish, birds) each year. Human health problems are associated with the ingestion of, and contact with cyanobacterial blooms and their toxins. Modes of action of cyanobacterial neurotoxins, hepatotoxins and skin irritants are considered. Recent indications of the accumulation of cyanobacterial toxins in fish, their effect on crop plants and their association with the deaths of human dialysis patients are discussed. These findings and events indicate an incomplete understanding of the exposure routes of these natural toxins and the need for greater awareness of their occurrence and properties among users of waterbodies which are prone to cyanobacterial bloom development.
