McCain Added 05 Jan 2017 'McCain is the largest purchaser of British potatoes in the UK, working with over 300 Red Tractor Assured growers and farmers. Carrying the Red Tractor logo on our product for ten years, our foodservice customers across all sectors can be confident that they’re purchasing only the best quality potato products. The McCain story in the UK begins in Yorkshire back in the 1960’s, right in the heart of prime potato growing country, and just down the road from our head office today. We’re still partners with some of the farmers who were with us at the start more than 50 years ago, and we’re proud to have close links to more than 3 generations of British potato growers. Although the way we grow, harvest and store our potatoes has changed a little since the 1960’s, our commitment to offering only the best potato products to our customers hasn’t. We work closely with our farming partners to ensure quality right from the start of the supply chain, something that is greatly supported by our membership of the Red Tractor Assurance scheme'.
