Do not go on to any farmland. Obey official road closed signs. Avoid startling livestock in case they panic and break through fences. If you come across patches of disinfected straw on the road, try to disinfect your tyres and your shoes. Avoid cycling in large groups - it can upset farmers and animals.
Farmers are desperate to protect their animals from infection.
You may find that some farmers have put road closed signs on public paved roads that go through or near their farms. The only time that a road is closed is by the police or council if a farm is infected and the stock have to be moved. It is up to you to decide whether to continue along a lane where an illegal road closed sign has been erected. Please do not be antagonistic even if pushed. If you are accosted by a farmer, show them the printout and tell them that you have a legal right to procede as do cars.
