Also known as “black mold” or “toxic black mold”, which are popular terms used to describe dark or black colored mold that may or may not produce toxic byproducts. These terms became highly publicized in the late 1990s and early 2000s when the potentially toxic and black colored species of mold called Stachybotrys was found at a number of properties with the occupants experiencing associated health problems. There are only a few species of mold that are potentially harmful in the toxic sense.
It is important to note that while any mold is potentially harmful to those with allergies or who have weakened immune systems, not all mold is toxic and not all toxic mold is black. Stachybotrys is a type of mold that is considered toxic. There are also other types of molds that secrete mycotoxins that do not have a dark or “black” appearance.
