Yes, mercury in tuna is still a problem, particularly in larger species like bigeye and bluefin tunas which accumulate higher levels of mercury due to their longer lifespans and higher position in the food chain. Limiting consumption of these types to once a week and opting for lower mercury species like light canned tuna is advisable for reducing exposure.

FAQs & Answers
