JACKSON, Miss. -- The Federal Emergency Management Agency says it's going to it temporarily suspend the sale and deployment of trailers for hurricane evacuees.
The agency says it will assesses health-related concerns involving formaldehyde levels.
FEMA provided about 120,000 trailers to victims of the 2005 hurricanes Katrina and Rita.
Some occupants last year began reporting illnesses, including nosebleeds and headaches.
The agency recently sent about 40 of the trailers to Miami, Oklahoma, where residents were forced out of their homes because of flooding.
Congressional leaders were outraged after documents revealed that FEMA lawyers had discouraged the agency from investigating reports that some trailers had high levels of formaldehyde.
The agency said in a statement that industrial hygienists, epidemiologists, medical toxicologists, and others were in Louisiana and Mississippi to gather information and review measurements that take into account relative humidity, trailer design and usage.
