Introductory speech by Caleb Rudd on behalf of Toxic Mould Support Australia

“Toxic Mould Support Australia, which I’ll refer to as TMSA, is a Facebook group that as of today has 3,312 members. It also has an associated website. The aim of the group and website is to raise awareness, and provide support to Australians suffering from health effects related to mould exposure. This includes the biotoxin illness Chronic Inflammatory Response Syndrome due to the environment of water-damaged buildings. Which I’ll refer to as CIRS from here on. This is a condition that I also suffer from.

Mold related illnesses, from mold allergy induced asthma to CIRS create a great burden of disease in Australia.

Daily, I hear the heartbreaking stories of those afflicted with chronic illnesses related to mould and see photos of terrible water damage to buildings. People write about how CIRS has devastated not only their health, but their relationships, their finances, and their faith in the medical, welfare and legal systems of this country.

I am here today to give voice to TMSA members, especially those who are not well enough to enter a submission to this inquiry.

Apart from the access to affordable medical care the issue of water-damaged buildings must also be addressed. There are fundamental issues with the design of buildings which includes the Australian building code, construction of buildings, their ongoing care and maintenance, and their remediation.

Patients struggle to find and afford healthy home and work accommodation. Landlords, real estate agents and insurance companies ignore their pleas for adequate remediation.

In summary, CIRS and other mold related conditions pose a significant public health and economic risk to Australia.

I look forward to discussing these issues with the committee roundtable session today.

Thank You.”

(From: Terms of reference web page)

  • CIRS – Chronic Inflammatory Response Syndrome. A complex multi-symptom, multisystem illness due to the exposure of biotoxins, inflammagens and toxicants in the environment.
  • WDB – water-damaged building(s).
  • CIRS-WDB – Chronic Inflammatory Response Syndrome due to Water-Damaged Buildings. Also known as mould illness, sick building syndrome. Not mould allergy, which occurs due to IgE antibodies produced via the acquired immune system upon inhalation of mould spores, but rather an chronic activation of the innate immune system, its inflammatory proteins and gene dysregulation, due to exposure to biotoxins.
  • CIRS-PLS – Chronic Inflammatory Response Syndrome – Post Lyme Syndrome aka Chronic Lyme disease. Borrelia spp bacteria and the parasite Babesia also produce biotoxins and can cause CIRS.
  • Biotoxin illness – Illness caused by biotoxins and inflammagens found in water-damaged buildings, bacteria and parasite infection (Borrelia spp. aka Lyme disease, Babesisos), Ciguatera, toxic blue-green algae.

Points to consider (Medical)

  1. We need epidemiological studies to determine the prevalence in the Australian population. McMahon 2017 estimated the prevalence of CIRS to be between 7-12.7% in children and at least 7% in adults in two small clinical studies in New Mexico, United States. 7% of the Australian population would amount to 1.73 million people in total (24,770,700 total, ABS Dec 2017).
  2. Considering the possible prevalence of CIRS in the Australian population there is a vast shortage of general and specialist practitioners who are knowledgeable in the screening, diagnosis and treatment of the condition. Most health practitioners are only aware of mould allergy.
  3. Specialist general practitioners who are knowledgeable about CIRS, and their patients,  should have access to MBS video consultation item numbers as many CIRS patients are bed and/or house bound or live substantial distances away from the small number of practitioners who treat CIRS.
  4. Chronic Inflammatory Response Syndrome (CIRS) should be a recognised medical illness throughout government departments, especially Centrelink, for disability pension and sickness allowance.
  5. Biotoxins and inflammagens found in water-damaged buildings are not limited to mould spores, but also fungal fragments, mycotoxins, mVOCS (microbial volatile organic compounds), VOCS from building materials, bacteria and bacterial toxins, viruses, parasites and more. Fungal fragments and toxins can persist even if mould is killed.
  6. Screening tools include visual contrast sensitivity testing (VCS) and symptom cluster analysis.
  7. Genetic susceptibility towards CIRS may be 24% of the general population (Dr. Shoemaker unpublished clinic data, Shoemaker et al, 2017)
  8. Accurate diagnostic biomarker testing is not available in Australia via a NATA/RCPA accredited laboratory for the following: Transforming growth factor beta 1 (TGB-b1), alpha-Melanocyte stimulating hormone (MSH), complement 3a (c3a), complement 4a (c4a), Matrix metallopeptidase 9 (MMP-9),and vascular endothelial growth factor (VEGF). These tests need to be a) available through common Australian pathology laboratories and have b) Medicare rebates available.
  9. Of those that are currently available some incur out of pocket costs (vasopressin/ADH, leptin). While for other accessible biomarkers (vasoactive intestinal peptide (VIP), estradiol, testosterone, serum osmolality, ACTH, cortisol, antigiladin antibodies, antiphospholipid antibodies) doctors are hesitant to request as bulk billed in case of Medicare audits.
  10. The primary medicine in the CIRS protocol, cholestyramine, is only available in Australia as Questran Lite (Aspen pharma care) that includes aspartame that many patients cannot tolerate. Most patients get the raw ingredient compounded without additives, leading to out of pocket costs.
  11. Secondary medicines; colloidal silver/EDTA nasal spray and VIP nasal spray are also compounded only medicines that also incur considerable out of pocket costs.
  12. CIRS and mycotoxins are linked to ME/CFS (Chester et al, 1994, Shoemaker et al, 2009, Gunn et al, 2016, Brewer et al, 2013), ulcerative colitis (Gunn et al, 2016), Alzheimer’s disease (Bredesen, 2016), Lyme disease (Shoemaker et al, 2008), Babesia (Shoemaker et al, 2006), Ciguatera (Ryan et al, 2015), Dinoflagellates/cynobacteria (toxic blue-green algae), (Shoemaker, 2001)

Points to consider (Water-damaged buildings)

  1. Problem of water-damaged buildings begins with the building code, design and building phases with increased energy efficiency leading to warmer, airtight buildings and non-awareness of vapour pressure management, causing condensation and mould growth even in new builds (Dewsbury et al, 2017). The recommendations of the Scoping Study of Condensation in Residential Buildings (Dewsbury et al, 2016) and the ABCB’s Condensation in buildings (2014) handbook need to be included into the Australian building code and made mandatory.
  2. Apart from design and construction issues water-damage can arise after construction due  to natural events (storms, hail, cyclones and flooding), pipe and appliances leaks and occupant behaviour (cooking, drying clothes, overcrowding, overfilling of bath or sink etc).
  3. Indoor Environmental Professional (IEP) of building testing needs to be standardised and include professional visual inspection, moisture testing, VOC testing and testing of settled dust via qPCR (ERMI, HERTSMI-2) among other methods. Inspection and scope of works must be done by different parties than those doing remediation to negate conflict of interest issues.
  4. Mould remediation industry in Australia is unregulated with many remediators not following ANSI/IICRC S520 Mold Remediation industry standards. Many are using fogging, spraying and gassing in lieu of source removal which is advised against in the standard as it does not solve the problem and often makes it worse (see Medical talking points 2).
  5. Insurance, real estate and assessment industries often use mould testers and remediators based on lowest price and not to the above ANSI/IICRC standards.
  6. CIRS-WDB patients may need a higher mould remediation standard than ANSI/IICRC S520, see Schwartz et al. (2016). Indoor Environmental Professionals Panel of Surviving Mold – Consensus Statement.
  7. Based on percent of water-damaged buildings (see below) many private buildings – homes, work places, shops, restaurants – are not safe for those with CIRS-WDB.
  8. Likewise many public buildings are not safe for those with CIRS-WDB – schools, universities, public housing, armed forces quarters, prisons, law enforcement offices, emergency services offices, libraries etc.
  9. No Australian tenancy laws explicitly mention mould. Tenancy laws should adopt the recent Californian law that requires landlords to give written disclosure to prospective tenants when the landlord knows, or has reason to believe, that mold is present in the building that either exceeds the permissible exposure limits allowed or poses a health threat. The landlord has this responsibility when the mold is visible, invisible, or hidden (
  10. The same should apply to residential and commercial building sales.
  11. Widespread awareness that killing mould with sprays (such as exit mould, vinegar and bleach) is not appropriate for anyone, especially for those with CIRS-WDB, rather prevention of moisture and then safe source removal of mould, is needed via public health initiatives.

  • 10-50% of all indoor environments in Europe, North America, Australia, India and Japan are affected by indoor dampness; the numbers are much higher in some areas
  • Microbial growth may result in greater numbers of spores, cell fragments, allergens, mycotoxins, endotoxins, β-glucans and volatile organic compounds in indoor air. The causative agents of adverse health effects have not been identified conclusively, but an excess level of any of these agents in the indoor environment is a potential health hazard.
  • Well-designed, well-constructed, well-maintained building envelopes are critical to the prevention and control of excess moisture and microbial growth, as they prevent thermal bridges and the entry of liquid or vapour-phase water. Management of moisture requires proper control of temperatures and ventilation to avoid excess humidity, condensation on surfaces and excess moisture in materials. Ventilation should be distributed effectively throughout spaces, and stagnant air zones should be avoided.
  • Building owners are responsible for providing a healthy workplace or living environment free of excess moisture and mould, by ensuring proper building construction and maintenance. The occupants are responsible for managing the use of water, heating, ventilation and appliances in a manner that does not lead to dampness and mould growth. Local recommendations for different climatic regions should be updated to control dampness-mediated microbial growth in buildings and to ensure desirable indoor air quality.
  • Dampness and mould may be particularly prevalent in poorly maintained housing for low-income people. Remediation of the conditions that lead to adverse exposure should be given priority to prevent an additional contribution to poor health in populations who are already living with an increased burden of disease.

    The recent enhancements of the National Construction Code have reduced the amount of energy required to heat and cool Australian homes. To date, the result of these changes, within Australia’s temperate and cool-temperate climates, is generally warmer internal temperatures. However, many of these warmer homes are presenting condensation and mould. This is demonstrating a general non-awareness of vapour pressure management within the Australian design and construction professions.”
