Have your say - estragole in fennel seed preparations

The European Commission requested EFSA’s assessment after concerns were raised by German authorities regarding fennel seed products intended for infants. 

Fennel seed preparations contain estragole, a naturally occurring compound that is genotoxic (may damage DNA) and carcinogenic.  

EFSA has reviewed the available scientific evidence on preparations of both sweet and bitter fennel seeds, which are commonly used in infusions and other food products such as spice mixes and supplements.  

EFSA’s scientists could not establish a safe level of exposure to estragole based on the available data, concluding that consumption of fennel seed preparations may pose a health risk, particularly for vulnerable groups such as babies, young children, and breastfed infants and fetuses when consumed by lactating or pregnant women.

Preparations where estragole has been removed by manufacturers during the production process or is undetectable are not considered to pose a health risk.

EFSA invites stakeholders, researchers, and members of the public to provide feedback on the draft opinion, available for consultation until 17 September 2025.
