CALAIS (AP) — Parts of the Maine coast have been reopened to shellfishing because levels of a potentially dangerous biotoxin have declined.

The biotoxin was produced by an unusual algae bloom. The Portland Press Herald reports the state has reopened some of the coastline between Calais and Cutler for the harvesting of clams, mussels and carnivorous snails. Clamming will also be allowed on a portion of the coast between Isle Au Haut and Winter Harbor.

Shellfishing on much of the state’s Downeast coast is still restricted because of the algae bloom, which produces a toxin that can cause amnesic shellfish poisoning in humans.
