Gruinard Island, Scotland, is officially declared free of the anthrax disease after 48 years of quarantine.

Gruinard Island ( GRIN-yərd;Scottish Gaelic: Eilean Ghruinneard) is a small, oval-shaped Scottish island approximately 2 kilometres (1+1⁄4 miles) long by 1 km (5⁄8 mi) wide, located in Gruinard Bay, about halfway between Gairloch and Ullapool. At its closest point to the mainland, it is about 1 km (5⁄8 mi) offshore. The island was dangerous for all mammals after experiments with the anthrax bacterium in 1942, until it was decontaminated in the late 20th century.
