However, you should ensure that your contractor takes every precaution to clean and disinfect his equipment between the farm and the roadway, and before going on to another farm. The same applies when you use your own equipment. Take particular care when working near fields that have animals in them. This is probably the real potential source of infection. If you have sufficient slurry storage then this may not be a problem for a few weeks.
Many farms have to apply slurry every day, or at least once a week.
Slurry can carry the FMD virus and spreading it with normal spreaders can send aerosols into the air. These aerosols will travel downwind and could infect your neighbours herd. Therefore take special care. Always taking care not to cause water pollution, try to spread slurry on land that is away from animals, preferable near your own farm rather than adjacent to a neighbours, and direct the slurry splash-plate downwards so that slurry is directed downwards rather than up into the air. Finally make sure that your tractor and tanker are pressure washed before and after use, kept clean, and disinfected with an approved chemical between each load.
