Nothing is certain in life you obtuse fucking cretin. Might as well not leave your basement because you can get run over by a car on the sidewalk. The risk can be lowered significantly, just like with any other condition. Don't ever move the goalposts in my presence again.

There's barely any mercury in fish rich in DHA. Fish need to have a diet rich in microalgae to be rich in DHA because microalgae are rich in it themselves. This means it's the bottom eater fish you want to eat that barely if ever eat any fish. High mercury accumulation only happens in predatory fish high in the food chain that eat other fish, thus also consuming mercury in them.
TL;DR eat sardines, salmon and atlantic mackerel. Mercury content is negligible to the point of not mattering if you don't eat kilograms everyday.
