Just how bad is black mould for your health?

Household mould, especially "black mould," is often feared, but the dangers are debated. While linked to allergies and asthma, evidence is weak connecting mould mycotoxins to serious illnesses. The fungus *Stachybotrys chartarum* can produce mycotoxins, but significant health issues from household mould exposure are unconfirmed. Removing mould remains important for respiratory health.
