HC Deb 11 March 1968 vol 760 c231W
Mr. Dalyell

asked the Secretary of State for Defence when he estimates that the island of Gruinard, off the north-west coast of Scotland, sprayed with anthrax in the 1940s as a test of microbiological warfare, will cease to be contaminated.

Mr. Mason

In view of the very persistent nature of the anthrax organism it is not possible to estimate how long the contamination will last.
