Black Mold is a toxic species of Stachybotrys mold which grows in poorly-ventilated—usually older—buildings.
In the game, Black Mold can be encountered while scavenging certain urban locations as a result of a scavenging accident. Therefore, keeping the "Safety" bar high lowers the possibility of mold exposure.
If the player character is exposed to black mold, he will suffer an allergy-like reaction that, while not directly harmful, has general negative effects on health restoration and fighting capacities, but only for for a short period of time.
