The Consumer Product Safety Commission released a report of an investigation it had requested be performed by the CDC's National Center for Environmental Health regarding deaths allegedly associated with exposure to imported drywall. The report concludes that the drywall was not a contributing factor in the deaths of the people who had previously lived in or visited homes reported to contain problem drywall.
The investigation included reviews of the pertinent medical records, interviews of witnesses, and available information from state public health authorities. The CDC review confirms the results of previous reviews conducted by CPSC itself. The cause of death in each case was clearly a primary, and often secondary, pre-existing chronic health condition. Subjects typically had multiple long-term, severe, pre-existing conditions.
