What You'll Learn
Studies have found microplastics in 90% of salt
Several studies have found microplastics in 90% of salt. A study by researchers in South Korea and Greenpeace East Asia found microplastics in 90% of the 39 salt brands tested worldwide. The study, which is the fifth on salt, looked at sea, rock, and lake salt sold globally. It found that microplastics levels were highest in sea salt, followed by lake salt, and then rock salt.
The presence of microplastics in salt is concerning because it is a widely consumed product, and the health impact of ingesting plastic is not yet fully understood. While some studies have suggested that microplastics may carry hazardous chemicals and microorganisms, the University of York's review of 320 existing studies concluded that there is "limited evidence to suggest microplastics are causing significant adverse impacts."
The source of microplastics in salt is likely due to plastic pollution in the environment, especially in waterways and oceans. The production process of salt, particularly the dehydration of seawater, can also contribute to plastic contamination. Sea salt is believed to be more vulnerable to plastic contamination than mined table salt, which has a lower risk due to its underground origin.
To minimize microplastic exposure, individuals can switch to high-quality sea salts like Himalayan salt, Redmond salt, or bamboo salt, which come from ancient, unpolluted seabeds. Reducing plastic use and switching to reusable alternatives can also help decrease plastic pollution and, consequently, the presence of microplastics in salt.

Plastic contamination is pervasive in the environment
Plastic pollution is one of the most pressing environmental issues, with plastic waste overwhelming the world's ability to deal with it. Single-use plastics, in particular, have contributed to a throw-away culture, accounting for 40% of the plastic produced annually. These plastics have extremely short lifespans, yet they can persist in the environment for hundreds of years, leading to pervasive plastic contamination.
This contamination is evident in the oceans, where plastic trash, carried by rivers and ocean currents, ends up in coastal waters and circulates globally. The plastic breaks down into microplastics, spreading throughout the water column and reaching even the most remote locations like Mount Everest and the Mariana Trench. These microplastics have been found in various ecosystems, from the Antarctic tundra to coral reefs, and have impacted numerous species.
The impact of plastic pollution extends beyond the natural environment. Plastic waste has also infiltrated built environments, with microplastics found in municipal drinking water systems and even the air we breathe. This has led to human exposure to plastic, with microplastics detected in our blood, lungs, and feces. While the exact health effects are still being studied, the presence of carcinogenic chemicals in plastic and their ability to leach into water are concerning.
One surprising source of plastic contamination is salt. Studies have found microplastics in sea salt from various regions, including the US, Europe, and China. This contamination occurs due to the process of dehydrating seawater, resulting in plastic particles ending up in the final product. With health officials recommending a daily salt intake, people may inadvertently ingest hundreds of plastic particles annually.
The pervasiveness of plastic contamination in the environment underscores the urgency of addressing plastic pollution. Reducing plastic waste, improving recycling efforts, and limiting single-use plastics are crucial steps towards mitigating this global issue.

Microplastics are tiny particles of plastic debris
The presence of microplastics in salt has raised concerns about potential health risks to humans. While the exact health impact of ingesting microplastics is not yet fully understood, detectable levels of plastic components like bisphenol A have been found in the urine of a significant percentage of the adult population. Additionally, the accumulation of microplastics in the gastrointestinal tract may have potential complications for human health. Researchers estimate that Americans may be ingesting upwards of 660 particles of plastic each year if they follow health recommendations for daily salt intake.
To minimize exposure to microplastics in salt, consumers are advised to opt for high-quality salts with non-plastic packaging. Himalayan salt, Redmond salt, and purple bamboo salt are recommended options as they come from ancient, unpolluted seabeds or have lower levels of microplastics. Additionally, reducing plastic use and switching to reusable water bottles can help decrease the overall presence of microplastics in the environment and, consequently, in salt.
While the health effects of microplastics in salt are not yet fully understood, the pervasive presence of microplastics in the environment and their entry into the human food chain is concerning. More studies are needed to comprehend the implications for human health and to address the global plastic pollution crisis effectively. In the meantime, individuals can take proactive steps to reduce their exposure to microplastics in salt and contribute to a broader effort to minimize plastic pollution.

Microplastics are found in seafood, tap water, and beer
Plastic pollution has become a significant environmental problem, with microplastics being found in seafood, tap water, and beer. These tiny plastic particles can be ingested by humans, leading to potential health risks.
Seafood
Studies have found microplastics in various seafood products, including fish, mussels, and bivalve mollusks. The consumption of contaminated seafood is a major source of microplastic ingestion for humans. For example, a study on mussels (M. edulis) sampled in coastal waters and UK supermarkets found that wild mussels contained up to 6.4 particles of microplastics per specimen.
Tap Water
Plastic pollution has been detected in tap water samples from around the world. A study by Mary Kosuth found that 81% of internationally sourced tap water samples contained microplastics. The particles were primarily fibers, ranging from 0.1 to 5 mm in length, with an average of 5.45 particles per liter.

Reduce plastic use to minimise microplastics in salt
Plastic pollution has become a pressing issue, with microplastics being found in various products, including salt. Sea salt, in particular, has been found to be contaminated by plastic, with studies showing that about 90% of sea salt contains microplastics. This is concerning as salt is a common ingredient in many people's diets, and the health impact of ingesting plastic is not yet fully understood.
To minimise the presence of microplastics in salt and reduce the potential health risks associated with plastic ingestion, it is essential to address the root cause: plastic pollution. Here are some ways to reduce plastic use and minimise microplastics in salt:
Reduce, Reuse, and Recycle:
The 3Rs – Reduce, Reuse, and Recycle – are fundamental principles in minimizing plastic waste. Reducing plastic consumption is the first step. Reusing items, such as shopping bags and containers, instead of disposing of them, helps keep plastic out of landfills and oceans. Recycling properly is also crucial, ensuring that plastic waste is transformed into new products rather than ending up in the environment.
Buy in Bulk:
Purchasing products in bulk can reduce the amount of plastic packaging needed. Buying larger quantities of items reduces the overall packaging required per unit, minimizing the potential for plastic waste.
Choose Alternative Salt Sources:
Opting for high-quality sea salts, such as Himalayan salt, Redmond salt, or purple bamboo salt, can reduce plastic contamination. These salts come from ancient, unpolluted seabeds, minimizing the risk of microplastic exposure. Additionally, bamboo salt may have the added benefit of removing impurities during the heating process.
Support Corporate Initiatives:
Encourage corporations to reduce their reliance on throwaway plastics. Support companies that use sustainable packaging and eco-friendly materials. By advocating for corporate responsibility, we can collectively reduce plastic pollution at its source.
Advocate for Better Waste Management:
Mismanaged plastic waste often finds its way into oceans and other water sources, contributing to the microplastic crisis. Support initiatives that promote better waste management practices, including proper disposal, recycling, and "dirty burning" techniques that use high temperatures and smokestack scrubbing to dispose of plastic waste.
By implementing these measures, we can reduce plastic use and minimise the presence of microplastics in salt, contributing to a healthier planet and safer food sources for all.
