A 61-year-old woman is dead and her 63-year-old husband is in hospital after an apparent carbon monoxide poisoning in western Newfoundland.

The couple was found by their son late Tuesday morning in their cabin on Portage Lake, off the Burgeo Highway.

They were at the cabin this past weekend, celebrating their anniversary.

Police said the incident is not suspicious.

The source of the carbon monoxide is unclear.

No names have been released.
