What are the Top 2 Mycotoxins in the home?
Stachybotrys chartarum Stachybotrys chartarum is cosmopolitan and grows naturally on straw and other cellulose containing materials in soil. In the indoor environment, this mould is commonly found together with Stachybotrys chlorohalonata on cellulose containing materials including paper, canvas and jute which are wetted to a water activity > 0.98. In a study conducted in Denmark, Stachybotrys chartarum was found to produce a number of mycotoxins inclduding macrocyclic trichothecenes, satratoxins and roridins when growing on building materials. 35% of the isolates from buildings produce SUPER TOXIC cytotoxic mycotoxins, the satratoxins. This led to the conclusion that idiopathic pulmonary hemosiderosis in infants is possibly not caused by satratoxins but by other S. chartarum mycotoxins. The optimum temperature for growth for Stachybotrys chartarum is 23 oC with a minimum and maximum temperature of 2 and 37 oC respectively. Aspergillus flavus Aspergillus flavus is widely distributed in
