ClearDetermination of particle abrasion through milling with five different salt grinders – a preliminary study by micro-Raman spectroscopy with efforts towards improved quality control of the analytical methods
Researchers used micro-Raman spectroscopy to measure whether plastic and ceramic grinding burrs in salt mills shed microplastic particles into the salt during milling. Plastic burr mills released significantly more microplastic particles than ceramic ones, confirming that everyday food processing equipment can be a source of microplastic contamination in what we eat.

Quantitative and qualitative evaluation of microplastics in different salts from Iran
Researchers analyzed microplastic concentrations in fifteen samples of crystallized, refined sea, unrefined sea, and rock salts from Iranian markets using scanning electron microscopy and micro-Raman spectroscopy, finding microplastic contamination across all salt types with concentrations varying by processing method.
Investigating microplastic release from plastic grinder heads during salt grinding
**TLDR:** Researchers found that plastic salt grinders release thousands of tiny plastic particles (called microplastics) into your salt when you grind it—with some grinders releasing over 15,000 particles per small container of salt. This means people may be eating more plastic particles than previously thought, since the grinder itself creates new plastic contamination beyond what's already in food from environmental sources. The study suggests using more durable materials for food grinders could help reduce how much plastic we accidentally consume.
Mechanical Grinding of Spices in Grinders with Polymeric Burrs and Transfer of Microplastics to Food
Polish researchers investigated whether grinding spices in plastic-burred mills transfers microplastics to food, finding that polymer particles from grinder components can contaminate spices during mechanical processing.
Investigating the Correlation of Microplastic Pollution Between Seawater and Marine Salt Using Micro-Raman Spectroscopy
Micro-Raman spectroscopy was used to investigate the correlation between microplastic contamination in seawater and marine salt from the same source waters, finding that the polymer profiles of microplastics in salt broadly reflect those in the seawater from which the salt was produced.
Detection and Characterisation of Microplastics in Food Grade Salts in India
Researchers analyzed 30 brands of food-grade salt available in India and found microplastics in all samples, with sea salt containing 13 to 27 particles per 100 grams and rock salt containing 8 to 29 particles per 100 grams. Particle sizes ranged from about 19 to 1,433 micrometers, and polyethylene terephthalate (PET) was the most commonly identified polymer. The study suggests that salt is a routine dietary source of microplastic exposure for consumers.
Detection of microplastic contamination in table salts in Padang City, Indonesia, and control strategies for choosing healthy salt
Researchers analyzed microplastic contamination in ten brands of table salt commonly consumed in Padang, Indonesia. The study found microplastic particles in all brands tested, ranging from 30 to 510 particles per kilogram, with fragments being the most common shape, suggesting that salt products represent a meaningful source of dietary microplastic exposure.
Identification and quantification of common microplastics in table salts by a multi-technique-based analytical method
Researchers developed a multi-technique analytical method combining microscope-FTIR and pyrolysis-GC/MS to identify and quantify microplastics in table salts, providing 3D information on polymer type, morphology, and chemical composition of food-grade salt contaminants.
Contamination of Indian sea salts with microplastics and a potential prevention strategy
All eight brands of Indian sea salt tested were found to contain microplastics, with concentrations ranging widely across brands, and the study proposed using improved salt harvesting methods to reduce contamination. The findings add to global evidence of widespread microplastic contamination in commercially sold sea salt, with direct implications for human dietary exposure.
Microplastic contamination in commercial salt: An issue for their sampling and quantification
Researchers analyzed microplastic contamination in commercial sea salt from three Italian salterns and found an average of approximately 1,653 microplastic particles per kilogram of salt. The study highlights important methodological considerations for sampling and quantification, noting that the physical characteristics and polymer types of microplastics varied across sampling locations.
Microparticles in Table Salt: Levels and Chemical Composition of the Smallest Dimensional Fraction
Analysis of commercially available table salts found microplastic particles and non-synthetic micro-particles in multiple brands, with the smallest size fractions being most abundant and most difficult to identify. The study raises concerns about human dietary exposure to microplastics through a universally consumed food product.
The presence of microplastics in commercial salts from different countries
Researchers analyzed 17 commercial salt brands from eight countries and found microplastic particles in all but one, with concentrations ranging from 1 to 10 particles per kilogram. The most common plastics were polypropylene and polyethylene, appearing mainly as fragments. While the estimated human intake from salt alone appears minimal, the study confirms that microplastics have infiltrated yet another everyday food product.
Detection and Characterization of Microplastics in Commercial Salts in India
Researchers detected and characterized microplastics in commercial salts available in India, including rock salt, sea salt, and table salt varieties. The study found widespread microplastic contamination across salt types, raising food safety concerns given the ubiquity of salt as a dietary staple.
Microplastic contamination in Indonesian consumable salts
Researchers analyzed both traditionally produced and commercial branded sea salts from Indonesia and found microplastics in all samples tested. Traditionally produced salts contained the highest contamination levels, with up to 3,753 particles per kilogram, though branded salts also contained significant amounts. The study indicates that sea salt is a notable dietary source of microplastic exposure for consumers.
Microplastic contamination and risk assessment in salts from India And Sri Lanka
Researchers analyzed microplastic contamination in commonly available salts from India and Sri Lanka, including sea salt, rock salt, and refined table salt. Microplastics were detected across most salt varieties, indicating that this staple condiment is a dietary route of human microplastic exposure in South Asia.
Analysis of the effect of salt processing on microplastic residues in crushed and washed sea salt
This study examined how standard sea salt processing — crushing and washing crude sea salt — affects the level of microplastic contamination. The processing removed between 56% and 98% of microplastic particles present in crude salt, reducing counts from around 256 particles per 10 g to as low as 6 particles per 10 g. The findings are reassuring for food safety but confirm that microplastics from marine pollution do enter the salt production chain and that processing steps matter for final contamination levels.
