To protect the farm against transfer of disease, disinfection is recommended. This includes a disinfection barrier in front of the total farm area and others before entering the different production departments on the farm. A simple method is to utilize a disinfection mat/bath to which a disinfectant is added. The shoes are disinfected when step-ping into this bath. It is, however, preferable to use a barrier where the shoes are changed. Having a clean zone, where people only walk in their socks is a possible solution here (Fig. 21.21). Clothes may also be changed in this zone. It is advantageous to use different colours for shoes and working clothes in the different departments. How much sectioning is to be done into separate departments with prior disinfection will always be a problem because it is costly, and more time is needed for changing, especially of clothes
