FSA/FSS Safety Assessment  

FSA/ FSS has undertaken a safety assessment of application RP1052b for the use of L-lysine base (liquid) produced by fermentation with Corynebacterium glutamicum (KCCM 80216 or KCTC 12307BP) as a feed additive for all animal species, from Daesang Europe B. V. 

FSA/FSS has reviewed the EFSA opinions (EFSA Journal 2020;18(12):6334 and EFSA Journal 2020;18(12):6333) and confirm that they are adequate for UK considerations and therefore a full safety assessment of this application was not performed by FSA and FSS. Please see the earlier section titled ‘Our safety assessment process’ to understand how and when we make use of EFSA opinions. 

The FSA/FSS opinion is that L-lysine base (liquid) additive, as described in this application, is safe and is not liable to have an adverse effect on the target species, worker safety, environmental safety and human health at the intended concentrations of use. The proposed terms of authorisation are set below. 

Any relevant provisions of retained EU law  

Under the requirements of the Regulation for feed additives: 

1. Article 16 and point 1(d) of Annex III: Labelling and packaging of feed additives and premixtures 

2. Article 21: Analytical methods have been verified by the European Reference Laboratory as used for the control of L-lysine base (liquid) in animal feed as detailed in the EURL analytical method evaluation reports (FAD-2020-0008). Valid analytical methods exist for: 

• the quantification of L-lysine in the feed additive, premixtures, feed materials, compound feed and water. 

3. Annex IV: The general conditions of use must be complied with, where applicable for the individual feed additive authorisation

3: Characterisation / identification of the active substance 

L-lysine base (liquid) produced by fermentation with Corynebacterium glutamicum (KCCM 80216 or KCTC 12307BP).  

• L-lysine (C₆H₁₄N₂O₂)  
• CAS no: 56-87-1 
• EINECS no: 200-294-2 

4: Conditions of use 

Species or category of animal	Maximum age	Content of L-lysine (mg/kg of complete feed with a moisture content of 12%)
All animal species	n/a	Minimum level: No minimum   Maximum level: No maximum

5: Other Provisions 

1. The lysine content shall be indicated on the labelling of the additive. 
2. L-lysine base (liquid) may be placed on the market and used as an additive consisting of a preparation. 

6: Analytical methods 

For the quantification of lysine in the feed additive and premixtures containing more than 10% lysine: 

Ion exchange chromatography coupled with post-column derivatisation and optical detection (IEC-VIS/FLD) – BS EN ISO 17180:2013. 

For the quantification of lysine in premixtures, feed materials and compound feed: 

Ion exchange chromatography coupled with post-column derivatisation and photometric detection (IEC-VIS) - Annex III, F of Retained EU Regulation 152/2009 (Determination of Amino Acids (Except Tryptophane)). 

For the quantification of lysine in water: 

The EURL considered the following methods for the potential determination of lysine in water (as for other authorised sources of lysine): 

• Ion exchange chromatography coupled with post-column derivatisation and optical detection (IEC-VIS/FLD) - BS EN ISO 17180:2013.; or 
• Ion exchange chromatography coupled with post-column derivatisation and optical detection (IEC-VIS) - Annex III, F of Retained EU Regulation 152/2009 (Determination of Amino Acids (Except Tryptophan)). 

Other relevant information (separate to terms of authorisation) 

1: Supplementary information  

Feed additives are subject to UK health and safety legislation. The safety assessment identified no specified hazards. 

Major animal species and their subgroups are defined in Annex IV of Retained EU Regulation 429/2008. 

The FSA/FSS consider there is no basis to propose specific requirements for a post-market monitoring plan other than those established in Retained EU Regulation 183/2005 ‘Feed Hygiene Regulation’ and Good Manufacturing Practice.
