The chief executive of the National Beef Association (NBA), Neil Shand, has said the UK beef industry is at a crossroads and either needs to step up and deliver more products or accept that imports will be required to fill empty spaces on supermarket shelves.Writing in the weekly NBA newsletter, Shand pointed to a recent analysis from Quality Meat Scotland (QMS) which suggests the UK will need to produce an extra 100,000t of beef by 2030 just to maintain current self-sufficiency levels.
