What it is

Natamycin is a natural antifungal compound produced by the bacterium *Streptomyces natalensis*. It is typically produced through fermentation and then purified.

Health notes

Regulatory bodies like the European Food Safety Authority (EFSA) have also evaluated natamycin. It is not known to cause adverse health effects at the levels typically consumed in food. Evidence does not suggest significant health concerns associated with its use as a food preservative.
