Is There A Way To Estimate Length Of Time A Fungal Colony Has Been Growing?

Question: Is there a way to estimate the length of time a fungal colony or colonies have been growing? I’m sure that is based on the type of mold, water availability, temperature, food availability, etc. However, in the district we have found several mold growth areas that appear to have been active for several weeks (based totally on assumptions), not a matter of days as is relayed in the information provided.

Answer:. It’s difficult to tell the length of time a fungal colony or colonies have been growing. As you mentioned the rate of fungal growth will depend on water availability, temperature, food availabity, presence/absence of
growth inhibitors and most important the type of fungus. If we know the type of fungus and if it’s still actively growing,
then we can estimate the length of time the fungal colony has been growing. Under laboratory conditions, most fungi will
produce visible colonies in 3-5 days (some fast growing ones within 2 days) and produce spores within 5-10 days.

Should I Panic And Move Out Of The House Or Clean The Mold?

Question: Hi, I have a family of 4 and currently living in a basement home. Last year in August, we had a leakage right above of one the windows. I would say the amount of water that came is between 2-4 Litres of water. I had no idea and ignored the fact that mold could be a problem in the future. All I did was dried the water with cloth and never paid attention behind the drywalls. My problem is that I now see mold growing just right above the frame of the window which I believe is metal. My family has been sick for the past few months with fever and constant coughing. I’m not sure if it’s just the weather but I suspect it could be the mold in our room. I am now in the process of cleaning the window with moldcontrol which I purchased at homedepot. I also planned to look further and open the drywalls around the molded area. I was just wondering if I should panic and move out of the house OR simply clean the mold. I am also inquiring in how much does it cost to get an air sample to test for mold right after the cleanup.

Any of your input would be greatly appreciated.

Answer: It’s possible that you had a major leak or even slow leak that has been there for some time. It’s likely that there is more mold growth than what you see. Instead of trying to clean the mold yourself, I would suggest you ask the homeowner to deal with the problem themselves. While you should not panic, you should ensure the mold is properly cleaned by qualified professionals.

Do You Know Of Specific Blood Tests For Molds?

Question: My husband and I were exposed to extremely high levels of Aspergillus (indoor count 33,000 ppm-outdoor count 400-500 ppm), Stachybotrys, Penicillium, Chaetomium, Cladasporium and a few others…

This exposure was over a period of 2 1/2 years. We didn’t know the mold was in our home and we and the doctors could not explain or diagnose our symptoms (ie: bleeding noses, flu like symptoms, chronic fatigue, aches and pains…just to name a few). We both have tumors (lungs, liver, ovaries). Do you know of specific blood tests available in Canada to test for the molds listed above. We have been tested for Cryptococcus gatti but realize that this is not for all mold types. Our doctors are unwilling to accept the idea that the molds in our home caused our symptoms or made us sick. Please, can you help?

Answer: Were the spore counts reported as parts per million (ppm)? Mold spore counts are usually reported as spores per cubic meter of air and not as parts per million (ppm). That’s beside the point. You wanted to know whether there are specific blood tests available in Canada to test for the molds Aspergillus, Stachybotrys, Penicillium, Chaetomium, and Cladosporium. I believe there are, although I don’t know who is doing it. The tests may not be available for some species.

The test is based on mold-specific antibodies. The presence of antibodies in the blood only indicates that one has been exposed to mold at some time. It does not indicate when one was exposed, where the exposure took place, or how much of mold one was exposed to. Therefore, a positive test for mold-specific antibodies alone is generally not enough to prove that health effects reported by individuals in moisture-damaged buildings are caused by exposure to mold.

Do I Vacate The Property Until The Mold Is Remediated?

Question: If penicillium/aspergillus-like spore counts are 4,700 and outdoor is 100, does this warrant vacating the property until the mold is remediated? I believe the mold has been there for close to 2 years and I have symptoms such as chronic yeast infections of armpits and rash on face, open sores on arms and severe chemical sensitivities.

Answer: Currently there is no set safe or unsafe number for airborne fungal spores. You have indicated that you have symptoms such as chronic yeast infections of armpits and rash on face, open sores on arms and severe chemical sensitivities. In that case you may consider to vacate the place during remediation.

Can Houses Suffer From Bacterial Infestations?

Question: Hi, I recently bought and moved into a new build property.  Having suffered with increasingly sensitive skin (became very red when bathing, touching skin) I moved out after 6 weeks.  Having removed carpets and repainted I am still getting a very clear skin reaction after having spent time in the house, unless I wash my skin almost immediately. Could this possibly have a bacterial component- for example if the drains haven’t been fitted properly- the house does have, what I would term, a ‘dirty plastic’ smell upstairs. I have also tried a powerful air-purifier which hasn’t really helped. Can houses suffer from bacterial infestations? Any advice would be much appreciated. This has been a very stressful situation. I live in England.

Answer: Yes, a house can be infested with bacteria. It’s difficult for me to know whether your skin condition is due to bacteria or other biological or chemical irritants. I would suggest you seek advice from a dermatologist.

It is the cause of Legionnaires’ Disease, a severe form of pneumonia and, it is the cause of Pontiac fever, a non-pneumonic form of L. pneumophila infection. Legionella spp.’s mode of transmission is through aerosols or aspiration of contaminated water.

The Indoor Mold Is An Early Warning Device

The mold (or mould, in the Queen’s English) has been the victim of a bad press. Mention the word and it conjures up an image of something rotting or in the process of decomposition. And yet, were it not for the mold that inspired the discovery of penicillin millions of lives would have been lost. […]
