Yesterday the Food Standards Agency (FSA) finally announced that it's going to review its misguided policy advising us all to eat at least two portions of fish every week. The independent watchdog, which is charged with protecting the public interest on food safety and health issues, has been pushing the 'two a week' figure in recent years - conveniently overlooking the fact that our over-exploited fisheries can't possibly sustain the increases in fishing needed to meet this level of consumption.
