Just as the title says. People talk about it, but I've never heard of people developing symptoms, or being diagnosed with mercury toxicity or anything like that. To me it seems like a bunch of scary hearsay, honestly. Prove me wrong.
As it stands, I'd like to eat a can of solid light tuna a day. Maybe two. Is that so wrong?

Selenium protects against mercury toxicity, and 16 of the 25 highest dietary sources of selenium are ocean fish
If a fish contains higher levels of selenium than mercury, it is safe to eat
Most species of commonly eaten fish in the U.S. have more selenium than mercury
Fish are not significant sources of PCBs and dioxins when compared to meat, dairy or vegetables
The benefits of eating fish regularly far outweigh the potential risks, which are neglible
Pregnant mothers and young children should eat 2-3 servings of oily ocean fish each week
The conclusion is obvious: fish should be a part of our diet. But is it safe to eat fish?
You might be surprised to learn that the answer is a resounding yes. In this article I???ll demonstrate that concerns about toxins in fish have been overblown, and that there is almost no risk associated with eating fish when a few simple precautions are taken.
The above are just excerpts; read the whole thing at the link.

My naturopath is really, really concerned about heavy metals toxicity from things like mercury and lead. He doesn't want me eating any farmed fish. He studied under Dr. Crinnion - here's some stuff I pulled from his website, drcrinnion.com on mercury specifically:
Mercury ??? Mercury is another one of the heavy metals that is found in all persons tested. Mercury comes in various forms: elemental, organic and inorganic, all of which are toxic. The two biggest sources of mercury are fish, containing methylmercury (an organic form), and dental amalgams containing elemental mercury. Candida albicans and other intestinal flora can methylate elemental mercury leading to higher methyl mercury levels in the body. The half-life of elemental mercury in the blood is 50 days, while organic mercury takes 70 days to reduce itself by 1/2. The greatest stores of mercury in the body are found in the kidney, liver, GI tract and the brain. The half-life of mercury in the brain is 20 years.
Current Sources of Mercury
Mom ??? placental transfer
Fish ( shark, swordfish, king mackerel, tuna, orange roughy, marlin, Chilean bass, lobster, halibut, snapper)
Skin lightening creams
High fructose corn syrup (and foods with high levels of this product)
Elemental mercury from broken thermometers or other sources
Health Problems Associated with Mercury
Anger, Irritability, Mood Swings
Infertility (male and female)
High blood pressure
Agents PROVEN to mobilize mercury from the body:
Dimercaptosuccinic acid (DMSA) this oral agent is safe and effective for the mobilization of mercury from the body at the body-weight dose of 30mg/kg/day (typically used as 10mg/kg three times daily). This has been safe and effective even for children as young as 12 months of age. DMSA is also quite effective for mobilizing lead (for which it has a higher affinity than mercury)
2,3-Dimercapto-1-propanesulfonic acid (DMPS) is available both as an injectable and oral agent that is both safe and effective for the mobilization of mercury and arsenic. DMPS also moves lead to a small extent.
Chlorella & Cilantro are commonly used for this purpose but have failed to show any evidence of effectiveness in all the trials that have been done.
Whichever of these agents is chosen, should be used as part of a complete protocol with nutrient support, avoidance of current exposure, nutrients to protect the kidneys and reduce hepatic and renal recycling of lead.

I've read anecdotal stories of people getting mercury toxicity from tuna, but haven't known anyone in real life.
Just saying, but that seems like a lot of tuna to me. I personally wouldn't eat that much, and I'd definitely switch to Skipjack, which is lower in mercury.
Why take the risk that you'd give yourself brain damage?
