Opinion of the Scientific Panel on Additives and Products or Substances used in Animal Feed on the safety of the new granulate formulation of the enzyme preparation Grindazym GP, and its extension of use as feed additive for ducks
2005
(FEEDAP), EFSA Panel on Additives and Products or Substances used in Animal Feed
The European Food Safety Authority (EFSA) received a request to deliver an opinion on the safety of a new granulate form of the enzyme preparation, Grindazym GP (enzyme E 1609), which is a preparation of endo-1,4-beta-xylanase and endo-1,4-beta-glucanase produced by Aspergillus niger for chickens for fattening, turkeys for fattening and piglets, for the consumer, the user, and the environment. EFSA was also requested to assess the safety of the existing enzyme preparation for the target species ducks for fattening. The safety of the product Grindazym GPL 15000 for ducks for fattening is demonstrated in a single study at approximately 15 times the intended use level, which showed no adverse effects over a period of 35 days. Considering also that Grindazym GP is already approved for chickens for fattening and turkeys for fattening, major species that are physiologically similar to ducks, the FEEDAP Panel concludes that the additive is safe for use in the feed of ducks for fattening. The data provided on composition, formulation and stability of the new granulate product demonstrate that it does not differ significantly in the content and source of the active ingredient, from the existing registered product Grindazym GP 15000, GPL 15000 or 15000MG. Since the new formulation does not alter the nature of the exposure compared with the existing product there is no reason to expect that it will present any novel safety issues for the target species, consumer, or the environment. In practice, re-formulation as a granulate may reduce the hazard for the user. FEEDAP Panel thus considers that the new formulation is acceptable for use as proposed.
