Can black mold cause respiratory problems? 

In a residential setting,  people are generally exposed to black mold through breathing in mold spores and mycotoxins. When ingested, mold spores have the potential to cause irritation and a burning sensation in air passages, such as the nasal cavity, mouth, and throat.
