I have no idea where you read that but it's completely wrong
mercury poisoning from chunk light tuna (the most common type) is basically impossible unless you're eating 4-5 cans a day for months
Albacore and yellowfin have 3x as much mercury as chunk light (and less selenium, which has an anti mercury absorption effect on your body), and the only recorded cases of mercury poisoning have come from albacore tuna. The fisherman guy that got poisoned was eating the equivalent of over a pound of albacore each day for months.
