Pollution from plastic waste has attracted attention due to the long-term durability of plastic waste in the environment and its adverse effects on marine fauna as well as humans. Despite the occurrence of microplastics in sea salt consumed by humans in several countries, there is no available information on the presence of microplastic in commercial salts produced in Brazil. This study analyzed five different brands of table salts and three brands of coarse salts from two main salt producing regions in Brazil (sea salts from Areia Branca City of Rio Grande do Norte State and lake salts from the Araruama lagoon, in Cabo Frio City of Rio de Janeiro State January). Samples were analyzed under a light microscope to verify the grain size and under a stereo microscope to visualize the plastic fragments. In addition, ATR-FTIR analysis was used to identify the type of microplastic. The results indicated that Brazilian commercial salts contained polyethylene and polypropylene. As table salts are used as condiment and food preservative, people are continually exposed to plastics. Therefore, more effective rules for regulating the salt refinement process are needed.
