How can you tell if a listing has Chinese drywall? It's a simple question without a simple answer. The Florida Department of Health has a Web site section devoted to the problem, however, and it updates information as it comes in. Since it helps to understand what kind of damage tainted Chinese drywall can cause, one section, "Case Definition with Pictures," includes photos of mirrors, pictures, pipes and other household items impacted by the drywall. The Web site also explains how the state plans to deal with the problem and includes details on how to file a complaint.
