Raw safety data returned.","data":{"risk_level":"high","summary":"Stachybotrys chartarum (formerly S. atra) is a cellulolytic mold that requires sustained water activity >0.94 and cellulose substrate, making it characteristic of chronically water-damaged buildings. It produces macrocyclic trichothecenes (satratoxins G and H, roridins, verrucarins) and is the most toxicologically significant indoor mold. Colonies are dark olive-green to black with a slimy appearance due to mucilaginous spore production. Unlike Aspergillus and Penicillium, Stachybotrys spores are not readily aerosolized from wet surfaces — disturbance (demolition, remediation) dramatically increases airborne concentrations. The 1993-1994 Cleveland cluster of acute idiopathic pulmonary hemorrhage in infants (10 cases, 1 death) in water-damaged homes initially attributed to Stachybotrys exposure by the CDC was later re-evaluated (insufficient evidence for causal link). Nevertheless, toxicological evidence from cell and animal studies confirms that satratoxins are potent cytotoxins at nanomolar concentrations. EPA/CDC guidance recommends remediation of any visible Stachybotrys growth. Not a primary invasive pathogen — health effects are predominantly toxin-mediated and immunological (inhalation of toxin-laden spores).","source_refs":["aletheia_fungi_batch_2026"]},"meta":{"synthesis_version":"n/a","timestamp":"2026-07-28T05:15:38.104Z"},"_notice":"ALETHEIA output is reference data, not professional advice.
