Could I Save My Clothing, Books, etc After Mold Contamination?

Jackson Kung'u

Question: Hi, I was wondering if you could answer a question for me. It is so hard to get any advice on this subject. My apartment had toxic black mold (Stachybotrys, Aspergillus, and Penicillium). It was a small area under a window. I was very sick and still do not know if I was just “sick” (flu like) or if it was the mold. Anyhow I moved out in May, and have been trying to salvage what I can from my apartment. I was wondering if I could save my clothing, books, etc? I have a microbial cleaner that says it can be used on paper. What do you think? There is no visible mold on any of my things. The mold was on the wall and in the air. Thank you so much for your time. I appreciate it so much.

Answer: Yes, you could save your clothing, books and other belongings. If the apartment had only a small amount of mold, I don’t think your belongings are significantly contaminated with mold spores. However, if you’re still concerned you could have the items that cannot be washed, cleaned with a HEPA vacuum. I would not recommend use of microbial cleaners unless it’s something already approved for that purpose. Items that can be washed should be washed and then dried properly immediately.

Indoor Air Quality: Testing for Mold Contamination in Buildings

Jackson Kung'u

Testing for mold contamination in buildings may involve collection and analysis of the following types of samples:

Air Samples

Air samples may be collected for total spore/hyphal fragment count (non-culture analysis) or for culture analysis. The analysis includes enumeration and identification of significant species. Both non-culture and culture analyses have some limitations. For example with non-culture analysis, identification of mold spores to species is difficult and for culture analysis only the viable spores/hyphal fragments are detected. In some situations, a combination of the 2 types of samples is recommended.

Tape, Bulk, Swab, Dust Samples for Direct Microscopic and Culture Analysis

Tape, swab, and dust samples are taken from surfaces suspected of mold contamination. For bulk, a piece building material such as a piece of carpet, drywall, insulation material or wood is collected. The analyses of these samples by direct microscopy allows identification to genus but experienced mycologists may identify some molds to species.

If identification to species is required, the samples are cultured in some suitable media. However, as was mentioned for air samples, only viable mold would grow in media. It is therefore recommended that both direct microscopy and culturing are used when identification of species is required.

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 Public Health […]

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. […]
