How does Safe Catch Tuna have the lowest mercury limit of any tuna brand?

Safe Catch developed a proprietary technology to rapidly test fish for mercury. Our testing technology has been certified by AOAC INTERNATIONAL as equivalent to ICP-MS testing methods utilized by the FDA. A Safe Catch mercury test is 250 times faster than an ICP-MS lab. AOAC International certification is the premier standard for verifying scientific testing methods and confirms Safe Catch is the undisputed authority in testing seafood for mercury.

We are not aware of any other brand besides Safe Catch that screens every wild tuna to a mercury limit.

Mercury levels between two individual tuna can vary widely even between two tuna of the same size, same school, and from the same location. We’ve tested over 6,000,000 fish for mercury levels.

About 1 out of 4 tuna tested do not pass our strict purity standards. (See: What do you do with the fish that don’t make the grade?)

That’s why Safe Catch tests to strict mercury limits and Safe Catch is the only brand that tests every single tuna and salmon for mercury.
