Mercury Poisening in tuna!?

True or false in cans

    Light tuna has less that white (younger fish).     But you got more than the safety limit for mercury in your childhood vaccinations so I don't see why they are worried about tuna.        

So white tuna (like albacore) has more mercury than pink tuna?  I thought it was the other way around.  I eat about 4-5 cans in a week, is this a cause for concern down the road?
