The article highlights the German government's investigation into the quality of minced oregano, which in 2019 revealed significant concerns with over 70% of samples containing high levels of pyrrolizidine alkaloids (Ap), a substance that can cause liver damage, and 20% of samples being adulterated. Following these initial findings, more comprehensive tests in 2021 showed a notable reduction in Ap levels, with 80% fewer alkaloids compared to 2019 samples. The tests also detected trace residues of pesticides and perchlorates, with some samples containing multiple pesticides. The latest testing, however, showed a significant decrease in adulteration, with only one sample out of 36 found to be contaminated, contrasting with a previous test that found only 60% of oregano samples to be pure.
