During this consultation period (June to August 2026), we received nine sets of comments and feedback from stakeholders.
Summary of feedback received
We received relevant comments on the following single ingredient feed (SIF) descriptions:
- multi-enzyme carbohydrases
- L-lysine solution from fermentation process
- carotenoid-based and carotenoid-related ingredients
- crystalline canthaxanthin
- crystalline astaxanthin
- crystalline astaxanthin dimethyldisuccinate
- Phaffia rhodozyma yeast
- Haematococcus algae meal dehydrated
- Paracoccus carotinifaciens fermentation product dehydrated
Multi-enzyme carbohydrases produced by __________ (name of the approved species of production organism)
In relation to the multi-enzyme carbohydrases consultation, we received two sets of comments from the same stakeholder.
The first set of comments focused on whether one of the stakeholder's registered products would fall within the proposed new multi-enzyme carbohydrases SIF description, given that the production organism used belongs to the species Trichoderma reesei. The SIF description that had been proposed in the consultation only listed Trichoderma citrinoviridae as an approved species of production organism for the production of the multi-enzyme carbohydrases. Based on the feedback provided and our evaluation of the organism, the species Trichoderma reesei will be added to list of approved species of production organisms within the SIF description.
The same stakeholder also submitted several questions related to the determination, approval, and registration of multi-enzyme carbohydrase ingredients, as well as the transition period and transition process for affected ingredients and registered feeds. All questions were addressed, and responses were provided directly to the stakeholder.
In addition, we recently completed a pre-market evaluation of a feed that is a source of multiple carbohydrase enzymes. The species of production organism used to produce the multi-enzyme carbohydrases was identified as Talaromyces versatilis. Based on the information assessed during the evaluation, we have decided to add Talaromyces versatilis as an approved species of production organism within the SIF description.
Based on adding other approved species of production organisms, the final description is:
Multi-enzyme carbohydrases produced by __________ (name of approved species of production organism) (or multi-carbohydrases produced by __________ [name of approved species of production organism])
is a multi-enzyme ingredient that contains 2 or more carbohydrases (for example, xylanase, glucanase, cellulase, amylase) which have enzymatic activities capable of hydrolyzing polysaccharides into oligosaccharides and/or monosaccharides. The ingredient is produced from a fermentation process conducted in accordance with good manufacturing practices. This fermentation shall be conducted using a single non-pathogenic strain of a microorganism, which does not contain a novel trait. The medium in which the microorganism is grown shall not be fortified with levels of substances, such as minerals and vitamins, above those required for optimal growth of the microorganism in the fermentation process. The ingredient shall not contain other extraneous materials except in such amounts as may occur unavoidably during good manufacturing practices. The multi-enzyme carbohydrases ingredient can only be obtained using an approved species of production organism as listed below.
The approved species of the production organism must be part of the name of the feed; for example, multi-enzyme carbohydrases produced by Trichoderma citrinoviride.
The following species are approved production organisms to produce multi-enzyme carbohydrases:
- Talaromyces versatilis
- Trichoderma citrinoviride
- Trichoderma reesei
The fermentation product type (for example, fermentation extract dehydrated) of the enzyme preparation shall be indicated on the label and may follow the enzyme name (for example, multi-enzyme carbohydrases produced by Trichoderma citrinoviride fermentation extract dehydrated). The fermentation product type does not need to be part of the name of the feed as long as the information appears on the label. In addition, the types of the carbohydrases may be included on the label (for example, endo 1,4 beta-xylanase, endo 1,4 beta-glucanase and xyloglucan-specific-endo-beta-1,4-glucanase produced by Trichoderma citrinoviride fermentation extract dehydrated).
The enzymatic activity unit definitions and the enzymatic assay conditions for each guaranteed carbohydrase shall also be stated on the label.
It shall be labelled with the following statements:
"This ingredient is approved as a source of multiple carbohydrases for use as a component of specialty feeds for livestock species."
"This ingredient is free of antimicrobial activity and is not a source of viable microbial cells."
To address worker safety concerns, it shall be labelled with the following statement:
"This ingredient may cause eye, skin and respiratory irritation and/or sensitization. Appropriate protective equipment must be worn during handling. / Cet ingrédient peut causer une irritation et/ou une sensibilisation des yeux, de la peau et des voies respiratoires. Un équipement de protection approprié doit être porté lors de la manipulation."
It shall be labelled with guarantees for minimum enzymatic activity of each carbohydrase expressed per gram or kilogram, and maximum percent moisture when the enzyme is presented in a dry form.
L-Lysine solution from fermentation process
Two sets of comments were received during the consultation period on the proposed new description for L-lysine solution from fermentation process. The first comment was a general comment and not relevant, and the second comment was with regards to adding an additional label guarantee for L-lysine solution.
After reviewing this comment and the information provided, it was determined that including a specific required label guarantee for L-lysine solution was not warranted. The required label guarantees for minimum percent L-lysine and maximum percent moisture are sufficient. The minimum of 50% L-lysine solution is a specification of this SIF and is included to describe the actual SIF.
Furthermore, the required label guarantees found in this new description also align with the required label guarantees for L-lysine solution (1-501-017) which has been chemically synthesized. Therefore, no changes will be made to the description that was consulted on.
Carotenoid-based and carotenoid-related ingredients
During the carotenoid-based and carotenoid-related ingredients consultation, two sets of comments were received. The first comment was a general comment and not relevant. The second comment from another stakeholder requested that the order of words in the descriptions of some carotenoid-based and carotenoid-related ingredients be amended. We have addressed this comment and will change the order from "skin and flesh" to "flesh and skin" in six amended SIF descriptions:
- crystalline canthaxanthin
- crystalline astaxanthin
- crystalline astaxanthin dimethyldisuccinate
- Phaffia rhodozyma yeast
- Haematococcus algae meal dehydrated
- Paracoccus carotinifaciens fermentation product dehydrated
As part of this ingredient consultation, we were also seeking feedback on the proposed definitions of two terms, "colourants" (subclass 6.6 – Colourants for livestock feeds) and "food modifying ingredients" (subclass 6.16 – Food modifying ingredients). Both of these terms are subclass names found in class 6 (Non-nutritive ingredients) in the Canadian Feed Ingredients Table (CFIT). These definitions were proposed to make sure the correct terminology was being used to distinguish SIFs that are approved to colour the livestock feed and SIFs that are approved to colour foods of animal origin. No comments were provided on the proposed definitions during the consultation period, so we will move forward with adding the definitions for the terms "colourants" and "food modifying ingredients" to the CFIT glossary at the next update of the CFIT.
Colourants are substances that modify the apparent colour of livestock feed.
Food modifying ingredients are ingredients which, when fed, modify the physical and chemical properties, or fortify or modify the nutritional composition of foods of animal origin.
We did not receive any comments that provided relevant information or raise concerns about the accuracy of the SIF description or any scientific data that should be considered before moving forward for any of the other new or amended SIF descriptions.
Outcome and next steps
Following these public consultations, we have finalized these new and amended SIF descriptions, which will be added to the CFIT at the next update. In addition, we will add the definitions for colourants and food modifying ingredients to the CFIT glossary.
We are committed to reviewing any new scientific information on the safety of any SIF. Anyone who becomes aware of new scientific information regarding the safety of these SIFs is encouraged to contact us.
