All that is required for fungal and bacterial growth is moisture or organic materials and people are exposed to thousands of microscopic mold spores every day. Problems are likely to arise when there is signiicant mould growth in an enclosed space with poor ventilation and a person is exposed to extremely high concentrations of microbial spores.

Exposure of mould primarily occurs throught inhalation. Spores can settle in the eyes, nose or lungs, potentially causing irritation or serious illness. There are hundreds of thousands of mould species, some of which are infectious, or pathogenic, while others are toxigenic agents that produce chemical by-products which may have adverse health effects. Individuals with allergies, asthma or a weak immune system are particularly vulnerable to mould related illness.

Fungal spores may not be carcinogenic, but with potential health effects like fever, asthma, nausea or sinusitis, it is very important to hire qualified professionals to clean up mould and ensure that the building is inhabitable, safe and everyone is protected from fungal exposure.
