The black mould that could be lethal to human being. Most types of mould have different degrees of health threats. Mould frequently also serves as a cultivation bed providing an ideal environment and nutrition to other bacteria and viruses.

Health Concerns

Mould presents a general health risk.

Mould can be a serious concern for people with respiratory issues

Studies have shown that more humid regions in the US with mould problems lead to a higher % of children developing Asthma.

Stachybotrys chartarum (often called “black mould”), which can produce mycotoxins and has been associated with severe respiratory illness in heavily contaminated environments.

Aspergillus fumigatus, a common indoor mould, can trigger asthma symptoms in sensitised people and may cause life‑threatening lung infections (aspergillosis) in immunocompromised patients.

Some Penicillium species commonly found on damp walls, furniture, and stored items are highly allergenic and can worsen asthma and rhinitis, and a few strains produce mycotoxins such as ochratoxin A, which is associated with kidney damage and potential carcinogenic effects after long‑term high‑level exposure. Public health reviews by agencies such as WHO and CDC now treat persistent indoor dampness and mould as a key indoor air‑quality risk that building owners have a responsibility to control.*
