FEMA-Provided Travel Trailer Study

CDC Takes Action

In the aftermath of Hurricane Katrina, the Federal Emergency Management Agency (FEMA) provided either mobile homes or travel trailers to displaced Gulf Coast residents who had lost their homes in the hurricane. Residents of these trailers and mobile homes have raised concerns about air quality in the trailers and the occurrence of respiratory and other symptoms resulting from exposure to formaldehyde or other respiratory irritants among residents of the mobile homes. CDC has been working with FEMA to investigate the health concerns of those living in the trailers and mobile homes and to take action to protect residents’ health.

Trailer Assessment Reports

On February 14, 2008, CDC released preliminary results from testing that found higher-than-typical indoor levels of formaldehyde in the travel trailers and mobile homes. Below is a listing of all of the trailer assessment reports available from the CDC.
