Sheep in some upland parts of the UK were subject to these controls under the Food Protection (Emergency Prohibitions) (Radioactivity in Sheep) Order 1991(SI 1991/5).
The results of a peer-reviewed assessment demonstrated that radiocaesium levels in sheep were a very low food chain risk, even to high-level consumers, and that controls were no longer necessary. All movement controls ended in Wales on the 1 June 2012. The ending of movement controls made the remaining legislation redundant.
Welsh Government has also revoked the associated Export of Sheep (Prohibition) Order 1991 (SI 1991/58).
