Should we be surprised?  I guess those signs we once saw sporadically posted around our rivers and streams are now a ubiquitous warning.

Scientists detected mercury contamination in every fish sampled in 291 streams across the country, according to a U.S. Geological Survey study released today.

About a quarter of these fish were found to contain mercury at levels exceeding the criterion for the protection of people who consume average amounts of fish, established by the U.S. Environmental Protection Agency. More than two-thirds of the fish exceeded the U.S. EPA level of concern for fish-eating mammals.

Currently reading “Tuna: A Love Story” by Richard Ellis and just had to post this quote I found quite humorous-

[Tuna] Does it contain  mercury? Well, yes, but the scientists and the tuna industry are still arguing about how much is bad for you, and that means you can keep eating it.

The above reminds me of something my organic chemistry professor once told all of us regarding carcinogens we just happened to be working with…they are only suspected carcinogens so just be a bit careful.  As for me [the professor] they were definitely not carcinogens when I was in college so they are perfectly fine for me to handle with no worries.
