Pyrrolizidine alkaloids in oregano

According to Commission Regulation (EU) 2023/915 of the European Commission amending regulation (EC) No 1881/2006 maximum levels of pyrrolizidine alkaloids in certain foodstuff apply.

The maximum levels refer to 35 pyrrolizidine alkaloids as mentioned in the respective regulation. A selection of the pyrrolizidine alkaloids mentioned below are within the scope of this ring test.

Dried oregano (millded) with spiked and incurred levels of pyrrolizidine alkaloids is provided as test material. The corresponding unspiked dried oregano is provided as blank material. The blank material might contain incurred levels of pyrrolizidine alkaloids.

The analytical data are assessed with respect to

the correct identification of the pyrrolizidine alkaloids,
the comparability (z-score), and
the trueness (70 to 120% of the spiked level, as far as applicable).

Reporting limits of at least 2 µg/kg are required for the individual PAs.
