Last updated: 05 September 2024

Animal Feed Additives 

During the 2023/2024 FY, the Committee considered thirty-five applications for authorisation of animal feed additives under assimilated Regulation (EC) 1831/2003. Members also reviewed and finalised the Committee’s Advice document for an additional six applications that were assessed in the 2022/23 FY. Details of all the applications considered by the Committee are given in the Table below.  

The FSA/FSS published 23 Safety Assessments based on the recommendations of the ACAF during this time. 14 of these were considered in meetings during the 2023/24 FY; the remaining 9 were considered in meetings prior to the period of this report.

Committee's response 

RP859 
 

Chlorophyllins 

  • Zootechnical feed additive proposed for use in poultry for fattening. 

  • Intended to function as a marker for detection of faecal matter contamination on carcasses. 

April 2023 

  • Due to gaps in technical documentation, additional information was requested from the applicant. 

  • The dossier remains under review. 

RP1039 
RP1040 

 
VTR-xylanase 

  • Zootechnical additive proposed for use in all porcine (RP1039) and avian (RP1040) species  

April 2023 
 

December 2023 

  • The Committee first considered these two linked dossiers in the April 2023 meeting. Due to gaps in technical documentation, additional information was requested from the applicant. 

  • The ACAF considered the additional information provided in the December meeting and were satisfied. 

  • Draft Committee's Advice documents are currently in preparation. 

RP1047 
 

Powdered dry Quillaja saponaria and dry Yucca schidigera (MAGNI-PHI®) 

  • Zootechnical feed additive proposed for use in all avian species (excluding laying and breeding birds). 

April 2023 
September 2023 
 

December 2023 
 

January 2024 

  • First considered by the Committee in the April 2023 meeting. Due to gaps in technical documentation, additional information was requested from the applicant.  

  • In September, the Committee reviewed the response to the request for information.  The applicant clarified which birds the efficacy claims should be extrapolated to, which the Committee deemed reasonable. 

  • The draft Committee's Advice document was reviewed in the December and January meetings.  

  • A Safety Assessment was published by the FSA/FSS in March 2024. 

  • Based on the Committee's advice, the FSA/FSS concluded that the additive is efficacious, and safe for the target species, consumers and the environment.  
    The additive is considered potentially harmful to the user by inhalation, and a potential eye irritant and skin sensitiser.  

RP1087 
 

Guanidinoacetic acid (Creamino®) 

  • Nutritional additive already authorised for use in chickens for fattening, weaned piglets and pigs for fattening.  

  • Applicant proposed an extension of use to all species.   

April 2023 
September 2023 
 

December 2023 
 

January 2024 

  • First considered by the Committee April 2023. Due to gaps in technical documentation, additional information was requested from the applicant.  

  • Additional information supplied was reviewed in the September meeting. Members were unable to conclude that the additive would be stable in breeder feed due to high temperature used in processing.  

  • The draft Committee's Advice document was reviewed in the December and January meetings.  

  • At the request of risk managers, the Committee considered whether reclassification as a zootechnical (as opposed to nutritional) would affect safety. The Committee concluded this would have no adverse effect on safety.  

  • The FSA/FSS published a Safety Assessment in March 2024. 

  • Based on the Committee's advice, the FSA/FSS concluded that the additive was correctly identified and characterised, and that the additive can be considered safe for target species, consumers, and the environment. The additive is not irritant to eyes or skin and is not a dermal sensitiser or toxic through inhalation, but due to the high dusting potential it is recommended that dust masks are worn by handlers.  

The additive can be considered efficacious for growing pigs and poultry, but no conclusion could be reached on efficacy for the other target species requested. 

RP593 

 
Endo-1,4-beta-glucanase (Hostazym® C)  

  • Zootechnical feed additive containing endo-1,4-beta-glucanase, produced by the fermentation of the strain Trichoderma citrinoviride (IM SD142).

July 2023 
September 2023 
 

October 2023 

  • Dossier first evaluated in October 2022.  

  • Committee reevaluated in April and July after requests for additional information. 

  • The draft Committee's Advice document was reviewed by members in the September and October meetings.  

  • The FSA/FSS published a Safety Assessment in December 2023. 

  • Based on the Committee's advice, the FSA/FSS concluded that previous conclusions drawn by The European Food Safety Authority (EFSA) could be accepted and the additive could, therefore, be considered safe for the target species, the consumer and the environment. The product should be considered a potential skin and eye irritant, and a potential skin and respiratory sensitiser. The additive remains efficacious and these conclusions can be extrapolated to the new uses proposed. 

RP309 
 

Endo-1,4-beta-xylanase (Hostazym®X) 

  • Zootechnical feed additive containing endo-1,4-betaxylanase, produced by fermentation of the strain Trichoderma citrinoviride (IM SD 135).

    for laying, weaned piglets, pigs for fattening, chickens reared for laying and  
    carp.

    suckling piglets, minor pig species for fattening and minor poultry species  
    reared for breeding. 

September 2023 
 

October 2023 

  • The dossier was evaluated previously by the AFFAJEG in 2021 and the ACAF in 2022.  

  • The conclusions by the AFFAJEG were reviewed and approved by the ACAF at their October 2023 meeting. The Committee agreed that the additive can be considered safe for the target species, the consumer and the environment. The ACAF agreed that the product should be considered a potential skin and eye irritant, and a potential skin and respiratory sensitiser, and the respirable particles were a potential hazard for the workers.   
    It was concluded the additive remains efficacious and that these conclusions can be extrapolated to the new uses proposed.

Members concluded that the silage additive Pediococcus acidilactici MA18/5M is not an eye irritant, skin sensitiser or skin irritant. Due to absence of evidence, all other additives in the application were considered potential eye irritants, skin sensitisers and skin irritants.
