Unlike bigger fish, sardines feed low on the chain, minimizing exposure. Long-tail phrases like "do sardines contain high mercury" often reveal misconceptions, but studies confirm low levels.

This is why queries about "why do sardines have mercury" point to environmental factors, not inherent high content. A PMC article explains that sardines' selenium content may even counteract mercury's effects, adding a protective layer.
For everyday eaters, this means you can enjoy them without constant concern. If you're curious about "mercury levels sardines," rest assured they're consistently low across tests.
