Systematic Development of Cattle Farm Epidemic Prevention Systems

No outside personnel are allowed to enter the cattle farm under any circumstances; when entry is necessary, they must change shoes and wear work clothing. Do not purchase forage or cattle from epidemic areas. Newly arrived cattle must be placed in an isolation barn for observation and rearing, and only after half a month, once confirmed healthy and disease-free, may they be transferred to the production barn. Farm staff entering the production area must also change into work clothing, shoes, and hats. Rearing personnel must not move between cattle barns, and must not borrow tools or equipment from other cattle barns. No other animals or poultry may be raised within the cattle farm.
