Safety and efficacy of FSF10000 and FLF1000 (3-phytase) as a feed additive for turkeys for fattening or reared for breeding, pigs for fattening and minor porcine species

Abstract

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 and efficacy of 3-phytase FLF1000 and FSF10000 as a feed additive for turkeys for fattening or reared for breeding, pigs for fattening and minor porcine species for growing. This additive contains 3-phytase produced by a genetically modified strain of Komagataella phaffii and it is authorised in the EU as a feed additive for feed for chickens for fattening, laying hens, chickens reared for laying and for minor poultry species for fattening or reared for laying/breeding. The applicant requested the extension of use of the additive (both forms) to turkeys for fattening or reared for breeding purposes, and the assessment of the solid formulation to be used in pigs for fattening and minor porcine species for growing. The FEEDAP Panel concluded based on previously evaluated data that the additive, in either form, is safe for turkeys for fattening or reared for breeding at the maximum recommended level of 1,000 FTU/kg feed. However, due to lack of data the Panel could not conclude on the safety for pigs for fattening or minor growing porcine species. The FEEDAP Panel concludes that the use of the additive under the proposed conditions of use is safe for the consumer and the environment. Both forms of the additive are not irritant to eyes and skin but should be considered a potential respiratory sensitiser. The liquid formulation is not a dermal sensitiser but the solid formulation is. The Panel also considered based on previously evaluated data that the additive has a potential to be efficacious as a zootechnical additive in turkeys for fattening and reared for breeding and in pigs for fattening and minor growing porcine species at 500 FTU/kg feed.
