In some cases companies produce feed materials out of other feed material. These feed materials do not necessarily have to be purchased from certified companies, if the feed materials are processed into a new feed material. The original feed material needs to ‘disappear’ due to combined chemical reactions such as enzymolysis, fermentation, hydrolysis and crystallization. The most important requirement is that the molecule structure changes.
For the production of, for example, magnesium phosphate, the feed material magnesium oxide is used. The supplier of the magnesium oxide does not have to be certified for GMP+, but the producer of magnesium phosphate must carry out a proper hazard analysis according to the HACCP principles (more information GMP+ D2.1 Guidelines HACCP GMP+). Based on the results of this hazards analysis, and also on the quality assurance which is applied by the supplier, the GMP+ certified producing company will make a selection of suppliers and will adjust his (entry) check accordingly.
NOTE: The company that purchases the non-certified magnesium oxide cannot sell this as GMP+ certified feed material
The flowchart gives an example of the production of a feed material using a feed material as raw material.
GMP+ International has a special database with information that can support you in carrying out your hazard analysis: FSP (Feed Support Products). Its interactive nature and the information contained in it, offers you a massive source of data which you can use in defining the risks of the feed ingredients you buy, but also in drawing up your HACCP plans. The FSP database can provide you with information about: the production process of feed materials, possible hazards, facts about hazards, the limits and monitoring data. Click here for access to the FSP database and search the feed ingredients you purchase to find the accepted products.
