EU assessment of the safety and effectiveness of phytase as a feed additive

On March 11, 2024, according to the European Food Safety Agency (EFSA), at the request of the European Commission, the EU Animal Feed Additives and Products (FEEDAP) research group issued a scientific opinion on the safety and efficacy of a 6-phytase  as a feed additive for all poultry, pigs, and finned fish.

Some original reports are as follows:

“Following a request from the European Commission, the EFSA 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 6-phytase produced by the genetically modified strain Aspergillus oryzae DSM 33737 (HiPhorius™ 10, 40, 20L and 50L) as a zootechnical feed additive for all poultry, all Suidae and all fin fish. The FEEDAP Panel concluded that the genetic modification of the production strain does not give rise to safety concerns. based on the no observed adverse effect level identified in a subchronic oral toxicity study in rats, the additive was considered safe for all poultry, all Suidae and all fin fish at the proposed conditions of use. The Panel also concluded that the use of the product as a feed additive is of no concern for the consumers and the environment. The liquid formulations of the additive are not skin or eye irritants. The two solid ones are not skin irritants but are eye irritants. Owing to the lack of data, the Panel cannot conclude on the skin sensitisation of the final formulations of the additive. Due to the proteinaceous nature of the active substance (6-phytase), the additive is considered a respiratory sensitiser. The Panel concludes that the additive is efficacious when included in the diet of poultry for fattening or reared for laying/breeding, reproductive Suidae, and all fin fish. Due to the lack of sufficient data, the Panel could not conclude on the efficacy for laying and reproductive poultry and growing Suidae.“
