Agriculture – Children and public safety
People often believe that farm children understand farm risks, but most children who die in farm incidents are family members. A few straightforward steps, and proper supervision of children, will reduce these risks. Other members of the public may also be at risk, eg when using public rights of way through fields containing cattle and calves.
