The Only Brand That Solves the Mercury Problem in Seafood
Why Mercury Matters
Industrial Pollution Drives Mercury Levels in Our Ocean
Mercury concentration has increased by more than 300% in the last 75 years mainly due to coal-fired power plants and industrialization.2
How Mercury Gets Into Our Food Supply
- Coal combustion and industrial processes release mercury gas into the atmosphere → Coal power generation remains one of the largest global sources of mercury emissions.2
- Mercury circulates through the atmosphere → Winds carry gaseous mercury globally before it returns to earth.2
- Rain and runoff deposit mercury into lakes and oceans → Mercury is deposited through precipitation and surface runoff into waterways worldwide.3
- Microorganisms convert mercury into methylmercury → In aquatic environments, bacteria transform inorganic mercury into toxic methylmercury.3
- Methylmercury accumulates in plankton and small fish → Bioaccumulation begins at the base of the food web.5
- Larger predatory fish carry the highest levels → Species like tuna and swordfish show the greatest mercury concentrations due to biomagnification.5
Because of these risks, public health agencies continue to issue fish consumption advisories,5 especially for pregnant women, infants, and young children.
Unmatched by other brands — Safe Catch sets a new standard in purity.
The Safe Catch Difference
Why Test Every Tuna for Mercury? (Even the Small Ones)
The answer is simple. Mercury levels vary widely in tuna of all sizes.2

Mercury in Seafood: Myth vs. Reality
Myth | Reality Check |
|---|---|
Smaller fish have less mercury | Tuna of all sizes vary widely in mercury.2 |
Pole & line caught = less mercury | Fishing method has no impact on mercury levels.2 |
All brands “mercury test” fish the same | Safe Catch is the only brand to test every single tuna for mercury and select only those that meet the strictest purity standards. |
The reality is, Safe Catch tests every single tuna and salmon with our own proprietary technology to mercury limits far stricter than FDA standards — and unmatched by other brands. That’s why families and health-conscious consumers can enjoy seafood with confidence.
