A CBBC Blue Peter presenter spent two days visiting a Dorset-based dairy farm to undertake an extreme cheese challenge, in preparation for Blue Peter's 60th anniversary.

Lindsey Russell visited Ford Farm to undertake the challenge, which will be part of the anniversary celebrations in 2018.

She spent two days undertaking various dairy production tasks, alongside other challenges for the hit show.

Martin Crabb, head cheesemaker at Ford Farm, was thrilled to be part of the filming, and is excited to see the finished result which will be broadcast on Blue Peter on February 9.

On day one of the challenge Lindsey visited Form Farm Dairy to make her own traditional cheese truckle.

She got a real hands on experience, from hand cutting and turning the heavy curds, pressing them into a 2kg mould, turning the pressed cheese and bandaging it in cloth.

On day two she then took the packaged cheese to Wookey Hole caves in Somerset to place the truckle in the cheese cave, where Form Farm cheddars are matured.

But for the TV show Lindsey had to undertake an extreme caving challenge, which included entering the cave half way up a cliff face.

She then crawled and tunnelled down before abseiling to the subterranean River Axe and climbing across a walkway bridge to safely delivering the cheese.

The Blue Peter trickle was then placed on a shelf in the cave where it will remain and mature naturally in the humid conditions until next January, when it will be moved to the Blue Peter studio for the milestone anniversary.

Martin said: "My children grew up with Blue Peter - in fact my younger son achieved a Blue Peter badge for a competition when he was nine-years-old.

"I may be a little over the target age of the Blue Peter audience now but I'm still just as chuffed to have played a part in it."
