That is why animal by-products are sorted into three categories: The highest risk material is Category 1 (Cat 1), intermediate risk material is category 2 (Cat 2) and material with a low risk is Category 3 (Cat 3).Дepending on the source of the raw materials and the intended use there are strict rules to achieve safe products. On the other hand, they are mainly of a high nutritional and energetic value and should be used in the best possible way to preserve resources. These materials bear the risk of transmitting diseases to humans or animals, if not processed properly.
