MAFF disinfectant figures assume clean surfaces

THE MAFF website should give us better guidance on the concentrations to use when dealing with farm situations when it is impossible to remove all organic matter on tyres, boots and straw mats.

Direct advice from the manufacturer caused us to use 400cc of concentrate instead of MAFFs 60cc when making up a 40 litres. Quite a difference.
