A LOGO which advises Bromsgrove and Droitwich Spa shoppers they are buying high quality farm foods has proved a success.

A National Farmers' Union survey showed one in three people recognises the little red tractor stamp of approval.

The British Farm Standard mark can be seen in all major supermarkets and corner shops.

The stamp of approval is on beef, lamb, chicken, pork, milk, vegetables, fruit and salad produced to tough hygiene, environmental and animal welfare standards.
