Two detectives have discovered that a fish restaurant in Hangzhou was using industrial salt in its dishes. Whilst eating off-duty at the very popular establishment, they noticed the fish to be especially salty. The suspicious men then took some leftovers back to the police station where drug tests proved negative. Returning the next day, as one detective ordered food the other snooped into the kitchen, and discovered a large bag labelled “refined industrial salt.” The owner, chefs and suppliers have been detained. The owner confessed it was done to cut costs. One netizen said normal salt is really cheap anyway.
