We know that black mold, along with many other types and colors of mold, can trigger severe allergies (stuffy head, headaches, itchy eyes, sinus issues, etc.) in some people who are sensitive.  Living with allergies like that is awful and miserable.  So in that sense, black mold can certainly make some people very sick. Black mold has not been scientifically proven to cause cancer.  But we know that it can cause major health problems in some people, such as pneumonia, that can lead to death if you can’t recover from it.  We think the talk about black mold being especially dangerous is an unfair connection to make, because lots of things can lead to pneumonia such as colds, flus, and other viral infections.  Black mold causes severe allergies in certain people who are sensitive.  That much we know for sure. Following the mantra that “no mold, no matter what color, belongs in a healthy home” is the best way to keep yourself and others safe from any mold symptoms.
