Tricothecene mycotoxins (toxic mold) grows on walls, behind walls, in the ceilings, under the carpets, in ductwork and crawnspaces.

Why do experts suggest you need to test after remediation to make sure it has all been removed?

Because common evidence of trichothecene toxicity are depression of immune responses and nausea, vomiting plus the usual respiratory culprits. Trichothecene mycotoxicosis was first recognized to be connected with alimentary toxic aleukia in the USSR in 1932. It is still dangerous but no longer has a 60% mortality rate.

Facts

  • Trichothecenes are 40 times more toxic when inhaled than when consumed orally.
  • Trichothecenes are found in air samples collected during the drying and milling process on farms, in the ventilation systems of private houses and office buildings, and on the walls of houses with high humidity.
  • Trichothecene is sometimes part of the “sick building syndrome”.
  • Trichothecenes include mycotoxins produced by Fusarium, Myrothecium, Trichoderma, Trichothecium, Cephalosporium, Verticimonosporium, and Stachybotrys.
  • Mycotoxin analyses of bulk environmental samples are now commercially available through environmental microbiology laboratories in the United States.

When levels of arsenic, cadmium, vanadium, and lead were tested in flooded Midwestern homes, totals were substantially higher than the maximum levels that the Environmental Protection Agency considers safe. It is not unexpected, since floodwaters are known to contain sewage, industrial waste, petroleum products, bacterial poisons such as E. coli and Vibrio vulnificus, biohazards (asbestos, PCBs and dioxin ) as well as construction material dissolved or degraded into standing water.

After the toxic soup dries, in the course of mud and debris removal, it is crucial to treat the area as a toxic zone and wear appropriate biohazard protective gear. Inhalation of toxic dust is obviously bad for your health. In addition to the sediment, mold growth of species such as the hazardous Stachybotrys chartarum will be difficult to control, especially if there are damaged roofs and plumbing, permitting water access to the area.

As any mold growth indoors is going to be destructive to construction materials–after all, mold feeds on cellulose–it is crucial to remove mold infested walls, roofing, etc. However professional mold assessment reports provide documentation on the type and quantity of mold for insurance purposes. Such documentation can prove very important from the courtroom to the hospital ward.
