Bleach Neutralizes Mold Allergens

Article excerpt

Researchers at National Jewish Medical and Research Center have demonstrated that dilute bleach not only kills common household mold, but may also neutralize the mold allergens that cause most mold-related health complaints. The study, published in the Journal of Allergy and Clinical Immunology, is the first to test the effect on allergic individuals of mold spores treated with common household bleach.

"It has long been known that bleach can kill mold. However, dead mold may remain allergenic," says lead author John Martyny, associate professor of medicine at National Jewish. "We found that, under laboratory conditions, treating mold with bleach lowered allergic reactions to the mold in allergic patients." The need for denaturing or neutralizing mold allergens is a critical step in mold treatment that has not been fully understood. Currently, most recommendations for mold remediation call for removal since dead mold retains its ability to trigger allergic reactions, according to Martyny.

The researchers grew the common fungus Aspergillus fumigatus on building materials for two weeks, and then sprayed some with a dilute household bleach solution, some with Tilex (a cleaning product containing both bleach and detergent), and others only with distilled water as a control. They then compared the viability and the allergenicity of the treated and untreated mold.

The researchers found that the use of the dilute bleach solution killed the A. …
