Study Strengthens Formaldehyde Link to Crippling Disease ALS
NBC News

Funeral directors who use formaldehyde to embalm bodies may be the most at risk, the researchers at the Harvard School of Public Health found.

Their findings, published in the Journal of Neurology Neurosurgery & Psychiatry, strengthen the links between formaldehyde and amyotrophic lateral sclerosis (ALS), also called Lou Gehrig’s disease. The condition, which gradually paralyzes patients by damaging their nerves, affects an estimated 30,000 Americans. It’s always fatal.

Veterans carry a higher-than-average risk, for reasons not fully understood.
