Microplastics in Sea Salt

• No Exception Found
• According to extensive testing data and environmental studies, sea salt is not completely free of microplastic contaminants.

• Source Water Pollution
• Because the world's oceans and seas are widely polluted with plastic debris, evaporating sea water to harvest salt inevitably captures these microscopic particles.

• Processing Limitations
• Standard commercial harvesting, washing, and filtering methods used for sea salt are generally unable to remove all microscopic plastic fragments.

• Comparative Purity
• If avoiding microplastics is a priority, unrefined sea salt tends to carry higher loads of particulate impurities compared to deeply mined, ancient rock salt deposits or highly purified vacuum-evaporated table salts, though modern contamination is globally pervasive.
