Dear Slaya
This question is from another thread, but I thought I’d post my response here for compactness.
Toxic mold has a number of weird characteristics that tend to cause people to inappropriately rule it out as a potential factor in CFS. Here is a summary of some of those.
1. Stachybotrys vs. Other Molds
Stachybotrys, which appears to be the most problematic mold in CFS, rarely grows in places where it can be seen or smelled. Thus, many buildings have severe Stachy problems without any evidence of its being there.
This mold usually grows inside walls, behind shower tile or (as in my house) behind other solid surfaces such as paneling. On those occasions when it can be seen, it usually looks like smears of dirt on the wall rather than mold.
Only if the walls (or whatever) are opened up does it look like mold.
However:
PLEASE DON’T OPEN UP THE WALLS TO LOOK AT THE MOLD! THIS IS VERY DANGEROUS!!!!
(CFS sufferers should never go looking for mold in their homes or try to remediate it themselves. They should be nowhere around when any remediations are done, and should hire a competent professional to do the job. I have seen CFSers experience permanent declines as a result of not following these recommendations, and Erik has seen many people get sick or die as a result of doing this type of do-it-yourself work. Be safe!!!)
Stachy doesn’t come up on most tests used by remediators either, as described in one of my posts earlier on this thread. So not being able to see mold, smell it, or find it on conventional tests gives no assurance whatsoever that it’s not there.
(Are we having fun yet?)
Stachy can grow synergistically with certain other molds. This is misleading as well. People get various tests done and find out, to their relief, that it’s “ONLY” X mold. Meanwhile, the hidden Stachy is ignored.
On the other hand, buildings can be quite moldy and not have any Stachy or other particularly toxic molds growing. This especially tends to be the case in damp climates.
Most non-toxic molds need a good bit of moisture in the air to grow. When moisture is present, these molds can just spring up “spontaneously” as a result of spores being blown in from outside and the water in the air.
Stachy grows under a very different set of circumstances. First, Stachy usually needs a water sitting for an extended period of time (24 hours or more) to get started. Thus, it is associated with “water events” such as leaks or floods. In some cases, the condensation in ductwork or in between walls (e.g. at the “condensation interface”) is enough.
If Stachy gets some water, it can grow even if the general humidity is low. 60% (which is the “comfort level” in climate controlled buildings) is plenty high enough. (More benign molds usually require more humidity to grow freely.)
Once a colony of Stachy has been established, it does not help to dry it out or kill it (e.g. with Thieves Oil). Dead colonies of Stachy are just as problematic as live ones. All that happens when a colony is dried out is that it releases a whole lot more dormant spores into the environment. (See abstract below.)
Stachy creates its poisons in order to coat all the surfaces of the environment. This is designed to prevent competitive molds from growing, thus allowing Stachy to grow more freely. (The poisoning that it does to people and animals apparently is just a side effect.)
A dwelling that has previously had a big Stachy problem thus will have poison spread throughout. This poison may keep occupants sick even if all the colonies have been properly removed. It also will make it more likely that Stachy (rather than competitive molds) will grow if conditions again become conducive.
Remediated buildings also will have lots of Stachy spores left, just waiting to spring up into live mold if they get some water.
Insofar as a building is remediated correctly and maintained carefully, it may be safe for people who are not already sick. However, it’s my belief that the amounts of mold toxins required to keep CFSers sick are often so low that recovery even in a house that’s been remediated may be extremely difficult.
Just because a house is moldy does not mean that it has Stachy in it. In fact, the presence of competitive molds can keep Stachy at bay. (This is the main reason why Stachy tends not to be found outdoors except under very specific circumstances.)
I don’t think that this means that it’s a good idea to let “benign” molds grow wild! Mold is unsightly, smells bad, damages property/possessions and causes allergies.
However, especially in a humid climate, the presence of obvious mold does not mean that Stachy or other particularly problematic species are present.
And just because it seems that there’s no mold at all is no assurance that that a horrific Stachy problem is not present.
2. New Buildings vs. Old Buildings
As Rock pointed out above, very new buildings MAY be less likely to have mold growth than ones that are a bit older. However, many times they go bad really fast.
Newer buildings tend to be built with characteristics (e.g. drywall, HVAC systems, lots of insulation, cheap construction) that lend themselves to mold growth.
In addition, a lot of building materials are stored in moldy warehouses or otherwise put into place “pre-molded.” The mold toxins on these materials have effects on those of us who are being especially scrupulous in pursuing avoidance. In addition, the spores present are sitting there waiting for a water event so that they can spring into live mold.
It’s hard to predict what buildings are going to be bad just from looking at them. Erik insists, “It is where it is.”
I personally get nervous about entering two specific kinds of buildings: ones with modern construction that look like they’ve been poorly maintained (especially if they have flat roofs), and ones that are sealed off with centralized duct systems.
I’ve never been in a big fancy hotel that felt good to me, for instance. Shopping malls and big office towers usually are problematic.
Buildings that fall into both of these categories (e.g. many schools and government buildings) tend to be the very worst, in my experience.
It’s impossible to know whether an “old mouldy Edwardian terrace house,” a “dry modern house” or an “old mouldy farmhouse” would be especially good or especially bad with regard to toxic mold.
“It is where it is.”
3. Progressive Effects
Another thing to keep in mind about toxic mold is that we’re not talking about an allergy. We’re talking about being poisoned.
If someone had a big exposure to nerve gas, we wouldn’t expect them to recover the moment they got away from it. And the idea that they might be especially susceptible if they got hit with the nerve gas again wouldn’t seem entirely unreasonable.
The same thing applies to toxic mold.
For at least some people, effects are cumulative. Just because you live in a building and aren’t being made deathly ill by it doesn’t mean that it’s not priming you for future serious illness.
Our belief is that once people get CFS, they tend to become much more affected by even small amounts of toxic mold. This means that even if a building isn’t that bad with regard to toxic mold, their “extreme reactions” to it may be keeping them much sicker than they would be if they were in a really good building.
These reactions may be so extreme that even moving to a really good building won’t make any difference, if people bring along all their contaminated stuff.
A main reason that people rule out mold as a factor in their illness is because “moving didn’t help.”
Those of us who have substantially improved or gotten well from mold avoidance wouldn’t have been helped much just by moving either.
Even moving to a really good building with only good stuff doesn’t result in a magic recovery most of the time. Toxic mold in the outside air can be an issue. Also, it can take the system a long time to address all the downstream effects and repair itself.
4. “Humid Days”
One issue that is really related to toxic mold “flares” is barometric pressure changes.
When storms approach, toxic mold colonies release their spores in the hopes of getting water to start a colony. This means that those affected by toxic mold tend to feel worse during those times.
In some cases, a severe storm will wash those released spores out of the air. Usually the outside air (and certainly the inside air) does not recover until the weather improves though.
Even in climates with little rain, spores are released at times of barometric pressure drops. Purchasing a device to measure barometric pressure (available at places like Wal-Mart) or just looking at the extent to which skies are sunny vs. cloudy can allow CFSers to get a sense of whether this phenomenon might be going on for them.
5. “Fresh Air”
Feeling better in fresh air is generally a good hint that toxic mold (or at least some substance present inside buildings) is a problem.
However, in some places, the outside air is severely affected by toxic mold. Pollution can affect outdoor air quality as well.
Therefore, not feeling better outside (especially on days that are not sunny) is not necessarily a good indication that toxic mold is not an issue.
Obviously, all of this makes the questions of whether CFSers are getting toxic mold exposures and whether they are affected by toxic mold really hard to answer.
That’s why it took me 12+ years to realize that mold was an issue for me.
I wish I’d understood that the possibility existed upfront. I’d have gotten to a higher level of wellness much more easily and quickly, and not wasted all those years doing nothing but lying in bed staring at the ceiling.
The only way to figure it out is to unmask in the way that Erik (the “Godforsaken Wilderness” sabbatical) and Dr. Myhill (“I’m afraid you’ll have to go on holiday”) recommend doing.
Best, Lisa

Mold
I have to admit that I'm not that familiar with the topic of toxic mould and at first sight it seems a little 'out there' to me. I've lived in old mouldy Edwardian terrace houses - while entirely healthy - and have been ill while living in three dry modern houses. I have noticed though that humid days make my problems much worse. I'm now living in a warmer, drier climate but in an old mouldy farmhouse with no change in symptoms. I always feel better outside in the fresh air though - so perhaps there is something in it. How would I know?
