Not kosher
Description: Natamycin, Pimaracin (preservative)
Function: preservative
Rationale:
Natamycin is produced by Streptomyces fermentation and is often used as a cheese-surface coating; O/K kosher notices show natamycin products sometimes require a dairy (O/KD) designation rather than plain pareve certification, so reliable certification verification is still warranted, keeping not_kosher.
If you don't see a status above, it does not mean the additive is not kosher automatically - it might just not be documented in our database yet.
