Recent research found that 90% of table salt used across the globe contained microplastics. Much of this is as a result of all the plastic waste in our oceans.

Refining reduces plastic
The results varied in amounts of microplastic density, with most of the Asian brands ranking especially high. The highest quantities of microplastics were found in salt sold in Indonesia which is one of the countries that suffers extensive levels of plastic pollution in the world. China refines its table salt prior to packaging and as a
It’s a direct result of our plastic-waste
Samples from sea salt contained the highest density of microplastics. This is as a result of the 13 million metric tons of plastic that ends up in our oceans every year. Second was
“The findings suggest that human ingestion of microplastics via marine products is strongly related to emissions in a given region,” said Seung-Kyu Kim, a marine science professor at Incheon National University in South Korea.
