Here, the school did the test based on a recommendation from the maintenance crew. The kind of mold found is not even the most dangerous. It is usually found on old bread and potatoes. It’s mostly harmless unless someone is immunosuppressed – which is probable given the age of the students. The report did not seem to mention Stachybotrys or other kinds of black mold. Still, the school decided it was unsafe and took responsible action by sealing off a section of the school and informing parents of the situation.
