How is natamycin used?
Natamycin is currently approved by the FDA for use on the surface of cuts and slices of cheese where the standards for such cheese provides for the use of safe and suitable mold inhibiting ingredients. Natamycin may be applied to cheese by dipping or by spraying a liquid solution that contains 200 to 300 parts per million (ppm) of the additive.

What are the health effects of natamycin?
Animal studies on rabbits, dogs, and cows indicate that natamycin has no toxic effects even at high levels of ingestion. In addition, natamycin was found to have no reproductive or mutagenic qualities. Animal studies also show that natamycin is fat and water insoluble, allowing an estimated 90% to be excreted through normal gastrointestinal functions. Natamycin was approved for use by the FDA and has been widely used in Europe for over 40 years.

What happens if natamycin is not used?
The use of natamycin on cheese allows manufacturers to produce cheese that is acceptable to the aesthetic demands of consumers (no discoloration or off flavors) by eliminating the growth of mold and yeast that occurs during aging and storage. Secondary benefits include reducing the risk of mycotoxin growth and longer shelf life.

What is the status of natamycin in the United States?
The FDA amended its food additive regulations to allow for the use of a dry mix of natamycin and cellulose (to prevent caking) on the surface of cuts and slices of cheese. The amendment excludes the use of the dry mix on grated or shredded cheese.
