> trust the nutrition label?
When its not imported. While FDA do occasionally take enforcement action against imports they generally have an expectation that other countries should regulate their own food labels even though the US is way more on top of it then the rest of the world.
With ingredients like this its always better to use USDA DB generic over the label/manufacturer submission directly anyway. They are only legally required to submit some nutritional information to USDA so manufacturer submissions often miss some micros.
