Safety of 3-phytase FLF1000 and FSF10000 as a feed additive for pigs for fattening and minor growing porcine species.

Following a request from the European Commission, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the safety of 3-phytase FLF1000/FSF10000 as a feed additive for pigs for fattening and minor porcine species for growing. This additive contains 3-phytase produced by a genetically modified strain of and it is authorised in its liquid FLF1000 and solid form FSF10000 as a feed additive for chickens for fattening, laying hens, chickens reared for laying and for minor poultry species for fattening or reared for laying or for breeding. The FEEDAP Panel has adopted an opinion regarding the use of this product as a feed additive in pigs for fattening and minor porcine species for growing. In that opinion, the FEEDAP Panel concluded that the use of the product as a feed additive would raise no concerns for the consumer safety nor for the environment but that the additive should be regarded as a potential respiratory sensitizer. The Panel also concluded that the additive has a potential to be efficacious in improving the phosphorus utilisation in the target species. However, the Panel could not conclude on the safety for the target species due to the limitations identified in the data provided. The applicant has now complemented the information and made it available to the Panel. The tolerance trial was done in weaned piglets in which the animals received up to 10 times the recommended dose of 1,000 FTU/kg feed. The results showed no adverse effects of the phytase on the performance of the animals or on the haematological and biochemical parameters measured in blood. Therefore, the Panel concluded that the additive (3-phytase FLF1000 and FSF10000) is safe for pigs for fattening and minor growing porcine species at the recommended dose of 1,000 FTU/kg feed.
