Consultation on natamycin and its associated end-use products, Proposed Re-evaluation Decision PRVD2024-02

Health Canada is consulting Canadians on the proposal to continue registration of products containing natamycin for sale and use in Canada, with proposed label updates.

Natamycin is registered to suppress dry bubble disease in mushroom production facilities. It is also registered for use as a preservative for samples of milk used in analytical testing laboratories.

Natamycin, also known as pimaricin, is a naturally-occurring antimycotic substance that prevents the germination of fungal spores. It is an important tool for mushroom growers to control integrated dry bubble disease management. It is also important to the dairy industry to preserve milk samples in analytical testing laboratories. Natamycin is also a food preservative that is approved and used in more than 150 countries around the world. Based on the current use pattern, natamycin has value in providing a pest management solution, and the potential risks to human health (dietary, occupational, and bystander) and the environment (aquatic and terrestrial organisms) are considered to be acceptable when products containing natamycin are used according to proposed label updates.

For a full list of products containing natamycin, please consult Appendix I in the Proposed Re-evaluation Decision or visit the Pesticide Label Search database.

For more information on the proposed decision open the "Proposed Re-evaluation Decision".
