Safety and efficacy of fumonisin esterase from Komagataella phaffii DSM 32159 as a technological feed additive for pigs and poultry

Fumonisin esterase produced from a genetically modified strain of Komagataella phaffi is intended to degrade fumonisin mycotoxins contaminants in feeds for pigs and poultry. The production strain and its recombinant genes are not present in the final product. The applicant selected 300 U/kg feed to represent a likely upper limit. This concentration showed to be safe for piglets, chickens and turkeys for fattening and laying hens; the additive is thus safe for those categories. This conclusion is extended to all pigs, chickens reared for laying and turkeys reared for breeding and extrapolated to all other poultry species for growing and laying and to minor porcine species. No evidence of mutagenicity or genotoxicity was detected and no evidence of toxicity from a repeated-dose oral toxicity study; the residue assessment did not identify any concern. The use of the additive is, thus, considered safe for consumers. The additive is not toxic by inhalation and the respiratory exposure is likely to be low; however, a risk of sensitisation via the respiratory route cannot be excluded. The additive is non-irritant to skin and eyes and is not considered a dermal sensitiser. No risks for the environment are expected following the use of the additive in feeds under the proposed condition of use. The additive has the capacity to degrade fumonisin contaminants in feed of marketable quality when used at the minimum recommended dose of 10 U/kg complete feed, as shown in studies with chickens for fattening, laying hens and weaned piglets. Since the mode of action of the additive can be reasonably assumed to be the same in animal species for which the application is made, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) considers the additive efficacious for all poultry and all pigs
