CBS 2's received countless phone calls and e-mails from parents living inside FEMA homes who say their kids are sick constantly -- they do not know for sure why -- and do not know what to do.

The Ruzicka family lived inside their home on 7th Street South West until the flood hit. At that point their home became unlivable and unsafe. And now the Ruzicka's family fears their new FEMA home is not safe either.

Melissa Ruzicka says both her two-year-old and two-month-old sons have the same symptoms: runny noses, bloody noses and sore throats -- all of these symptoms signs of formaldehyde poisoning.

Ruzicka took her children to the doctor Tuesday morning. Her doctor ran strep tests but found nothing. The doctor agrees Ruzicka's children are definitely sick but cannot say for certain why.

Ruzicka says she understands kids often get sick and pass germs back and forth to one another but says it's the not knowing for certain that makes her scared.

CBS 2 installed a formaldehyde test in the Ruzicka's home. That test needs to sit inside for about 24 hours before we can send the test off to the lab and get some results.

Meanwhile the Ruzicka's say they are waiting for FEMA to do something because they clearly cannot live in their flood home and depending on test results may not be able to live in their FEMA mobile home either.Formaldehyde Fears
