I only eat yellowfin tuna not..is it blue fin? I've read yellow fin is fine, blue fin isn't. I only have the little tins on crackers etc or cheese and vegimite ones. Thank you heaps for your concern I'll re-google to make sure the amount im consuming isnt too much only just found out I can't drink as much viten juice (mixed fruits)as i like because of the vitamin a levels in it its so yummy though!!
