In these materials, which can not be used in animal feed any more includes those tissues that have mounting risk of shifting the factor that is considered causing BSE. Brains and spinal cords of 30 months and older cattle are some of the major sources of these high risk cattle materials. There is a low risk of BSE among the cattle less than 30 months of age and the risk gradually increases among the cattle that are more than 30 months of age. It has also been banned if the entire dead body of cattle is not examined and supplied for human use.
