British Columbia reports spread of whirling disease in trout and salmon, urging precautions.

The British Columbia government has detected more cases of a parasite causing whirling disease in young trout and salmon. First found in Yoho National Park in September 2023, the disease can decimate up to 90% of young fish but poses no risk to humans. Officials suspect it spread from Alberta via human contact. To prevent further spread, the government advises boaters and anglers to adopt the "clean, drain, dry" approach and avoid moving fish between bodies of water.
