NFU has helped shoppers support British farming by launching an online supermarket sourcing guide.
Over the past 12 months, the union has been working to establish the ’sourcing policies’ of the major retailers own brand products.
Ruth Mason, chief food chain adviser at the NFU said transparency was the key to providing shoppers with the information which would enable them to buy British, as well as allowing farmers to produce for the domestic retail market.
Ms Mason said: "We want to promote British food to the general public and support shoppers who want to buy British food by helping them find it at different retailers.
"If consumers know who is sourcing from British farmers and growers, it allows them to make an informed choice about which retailers they then want to buy from.
"This guide enables them to evaluate the performance of their regular retailer in terms of supporting British farming.
“What is needed is transparency. The overriding message for consumers is to buy British food and use this guide to be savvy about retailer sourcing policies for own-brand products.
“We also want all of the major retailers to pledge their support for the NFU’s Back British Farming Charter.”
The online guide shows how Aldi and Morrisons were committed to 100 per cent British beef and lamb on their standard and premium lines, whereas Asda, The co-operative and Sainsbury’s only source 100 per cent British for their premium lines of beef and lamb.
The NFU has said as sourcing policies constantly change, the guide will be updated.
However, the NFU is calling for retailers to build more transparent and sustainable supply chains stating labeling was still confusing to understand which made it difficult for consumers to identify British produce.
This was particularly prevalent in the dairy sector.
But consumers could ensure they bought British by looking out for the Red Tractor logo with the Union Jack flag on it. This could then be traced back to a British farm.
