1. Look at the outer packing and see if it is exquisite. The packaging boxes of Argentine red shrimp imported through formal channels should all be in English and numbers except Chinese labels.

2. Check whether the Chinese label information on the packaging box is complete, and whether there is any vacancy in the information such as production date, shelf life, processor and importer.

3. Open the box cover. Authentic Argentine red shrimp should be caught from the sea and quickly frozen on a fishing boat. There should be no ice cubes or ice cubes between shrimps, so that the whole shrimp can be seen clearly and there will be no large area of ice cubes.

If all the above three points are met, it should be the authentic imported Argentine red shrimp.
