Here in Europe there are some shenanigans with extra virgin olive oil. In the best case, they are adding lower-grade olive oils in the extra virgin oil, or completely mislabeling virgin oil and lampante oil as extra-virgin. In the worst case, especially with oil coming from outside of the EU, they can mix it with other oils, like palm oil.

Honey is also problematic, with China exporting about 1.5 time more honey than what they actually produce..

Sometimes a dutch trader also mislabels Romanian horse meat as beef.
