My point was that all countries have big factories but in the US they are somehow unable to make sure no cross contamination occurs.

It’s just impossible because US scale /s

The EU allows cross contamination with the same "may contain" labeling as the US previously did.

Are you saying all other countries have zero cross contamination? Can you cite that?

It's possible for the US to take note of it because of scale. Doesn't mean it doesn't happen elsewhere.
