That's the important part. I was eating tuna it pretty much every day for about a year until I found out that it was dangerous. They don't even have warnings on the can. Tony Robbins fried his brain doing that[0]. Still just hoping that I didn't do any damage to myself.

The fishing industry lobbies have sued the FDA and other health organisations around the world to prevent then from requiring warnings on the label, and to get them to change the maximum PPM levels:

> However, the fishing industry sued FDA, arguing that the economic impacts of the standard were likely to be too severe. A court agreed, and FDA had to revise the Action Level, raising it to 1.0 ppm, the current level.[1]

> Scientists from the Environmental Protection Agency (EPA) estimate that as many as 600,000 babies are born each year at risk of neurological and developmental problems because their mothers have high blood mercury levels from fish consumption.[2]
