Health authorities in Iceland have halted sales of a beer containing whale meal.

A whaling firm named Hvalur was making the main ingredient for the beer, which is said to be derived from endangered fin whales but didn't have a license to produce it for human consumption, according to a release.

The Whale and Dolphin Conservation, an environmental group, criticized the plans to sell the beer containing whale meal.

Dagbjartur Ariliusson, owner of brewer Brugghus Stedji that planned to sell the beer, said the matter is being reviewed by their lawyer.

The beer was to be sold during the country‘s month-long Thorablatt festival, which is held in honor of the Norse god Thor.
