All samples
were compliant with EU legislation. However, the levels of coumarin (0.6–63 mg/kg) may result in an
exposure that, in case of children, would exceed the tolerable daily intake (TDI) of 0.1 mg/kg bw/day.
In addition to coumarin, estragole, methyl-eugenol, (R)-(+)-pulegone and thujone were EU-regulated
substances detected in thirty-one of the products.
