6. Description of content: Health Canada received a food additive submission seeking 
approval for the use o f chymosin  B from the yeast Kluyveromyces lactis  CIN in dairy 
products such as cheese, quark (a type of fresh cheese), and fermented milk products 
such as yogurt, kefir and sour cream.  
Chymosin B from other source organisms, including  Kluyveromyces marxian us var. lactis 
(DS1182) (pKS105), is already permitted for use in Canada as a food enzyme in the 
manufacture of v arious dairy products. However, K. lactis CIN has not previously been 
permitted as a source organism for any enzyme on the  List of Permitted Fo od Enzymes . 
The results of Health Canada 's evaluation of available scientific data suppor t the safety 
of chymosin B from K. lactis  CIN for use as requested by the petitioner. Therefore,  
Health Canada has modified the List of Permitted Food Enzymes  (http://hc -sc.gc.ca/fn -
an/securit/addit/list/5 -enzymes -eng.php ), effective 19 April 2017.  
The purpose of this communication is to publically announce the Department's decision 
in this re gard and to provide the appropriate contact information for any inquiries or for 
those wishing to submit any new scientific information relevant to the safety of this food 
additive.  
7. Objective and rationale: [X]  food safety, [  ] animal health, [  ] plant  protection, 
[ ] protect humans from animal/plant pest or disease, [  ] protect territory from 
other damage from pests.  G/SPS/N/CAN/1109

Animal Health Code, chapter number) :  
[ ] International Plant Protection Convention (e.g.  ISPM number) :
