ClearMicroplastics in bivalves cultured for human consumption
Researchers examined two commercially farmed bivalve species, mussels and oysters, and found microplastics in the edible tissues of both. Mussels contained an average of 0.36 particles per gram of tissue, while oysters had 0.47 particles per gram. Since these shellfish are consumed whole without removing the gut, the study suggests they represent a direct pathway for human ingestion of microplastics.
Exploring microplastics in commercial bivalve species and in bivalve aquaculture waters: Insights from the southern Pacific
Microplastics were detected in multiple commercially sold bivalve species (such as mussels and oysters) and in nearby inland and coastal waters. Because bivalves are widely eaten by humans, the findings raise direct concerns about microplastic dietary exposure through seafood consumption.
Plastics on the Half Shell
Researchers found that people who regularly eat oysters, mussels, and other bivalves may be consuming thousands of microplastic particles annually, based on Belgian studies measuring microplastics in commercially farmed shellfish. The findings provided the first direct evidence that microplastics enter the human diet through seafood consumption.
Microplastic contamination in filter-feeding bivalves inhabiting the natural ecosystem of Da Nang Bay: An investigation of oysters (Ostrea rivularis) and green mussels (Perna viridis)
Researchers found microplastics in 100% of examined oysters and green mussels from Da Nang Bay, Vietnam, with average densities of 3.5 items per gram of tissue, exceeding average contamination levels seen in seafood across Asia. Mussels showed considerably higher MP accumulation than oysters, with black plastic particles under 0.5 mm in fibrous form being the dominant type found.
Occurrence of microplastics in Mytilus edulis and Arenicola marina collected along the French-Belgian-Dutch coast
Researchers measured microplastics in blue mussels and lugworms collected from beaches along the French, Belgian, and Dutch coasts, finding microplastics in both species at levels reflecting environmental concentrations. The study bridged the gap between high-concentration lab experiments and field reality by documenting actual microplastic contamination in these commonly consumed and studied marine species.
Spatio-temporal contamination of microplastics in shellfish farming regions: A case study
Researchers assessed microplastic contamination in a major French shellfish farming region over one year, finding that mussels and oysters contained confirmed microplastics with polyethylene and polypropylene as dominant polymer types, varying by site and season.
Micro and Nanoplastics size distribution in mussel tissues: first evidence, identification, and quantification in the nanogram range
Italian researchers used a highly sensitive mass spectrometry technique to detect and quantify both microplastics and nanoplastics in farmed mussels, finding plastic particles in every sample tested. Nanoplastics in the 20–200 nm range were present in substantial quantities, and the authors estimate that European seafood consumers could ingest over 2 milligrams of nanoplastics per year through mussel consumption alone. This is one of the first studies to directly quantify nanoplastics in a commonly eaten seafood, raising significant concerns about dietary exposure.
Are bivalves a source of microplastics for humans? A case study in the Brazilian markets
Researchers found that all four species of bivalves sold in Brazilian markets contained microplastics, averaging 1.64 particles per gram, confirming that commercially sold shellfish are a source of microplastic exposure for consumers.
Microplastics in commercial bivalves from China
Researchers analyzed microplastics in commercially sold bivalves from China, finding contamination across multiple species and geographic origins, with implications for human dietary microplastic exposure through shellfish consumption.
Microplastics ingestions by wild and aquaculture marine bivalves: A systematic review on field investigation study
This systematic review of 33 studies found that shellfish like mussels, oysters, and clams from both wild and farmed sources contain microplastics. Since many people eat these shellfish whole, including their digestive systems, this represents a direct pathway for microplastic ingestion by humans.
Microplastic Concentrations in Two Oregon Bivalve Species: Spatial, Temporal, and Species Variability
Pacific oysters and razor clams from Oregon were found to contain microplastics, with concentrations varying by species, location, and season. The findings have direct relevance for human health since both species are commercially harvested and consumed.
Extraction and identification of microplastics from mussels: Method development and preliminary results
Scientists developed and validated a method for extracting and identifying microplastics from mussel tissue, then applied it to measure contamination in commercially harvested mussels. The method produced reliable, reproducible results, providing a practical tool for monitoring microplastic levels in one of the world's most widely consumed shellfish.
Towards Risk Assessments of Microplastics in Bivalve Mollusks Globally
Researchers compiled data from 22 countries to assess the risk of microplastic contamination in bivalve mollusks such as mussels and oysters. While most countries showed relatively low pollution levels, the chemical composition of the microplastics found in bivalves varied widely, with some polymers posing greater health concerns than others. The study estimates that regular consumption of contaminated bivalves could represent a meaningful pathway for human microplastic exposure.
Occurrence, sources and potential human health risk of microplastics in seafood species
Researchers measured microplastic occurrence in seafood products available in local markets, identifying plastics in multiple species including fish, shrimp, and bivalves, and estimated potential human dietary intake based on consumption data. The study found that seafood lovers could ingest thousands of microplastic particles per year through regular consumption, with shellfish representing the highest per-serving exposure.
Abundance and characterization of microplastics in wild and cultured blue mussels (Mytilus edulis) and American oysters (Crassostrea virginica) from Nova Scotia
Researchers quantified and characterized microplastics in wild and cultured blue mussels (Mytilus edulis) and American oysters (Crassostrea virginica) from Nova Scotia, assessing how plastic contamination varies between farmed and wild bivalves in Canadian coastal waters.
Microplastics in mussels sampled from coastal waters and supermarkets in the United Kingdom
Researchers measured microplastic contamination in mussels from U.K. coastal waters and supermarkets and found anthropogenic debris in every sample tested. Wild mussels contained up to 2.9 debris items per gram of tissue, while supermarket mussels showed lower but still consistent contamination levels. The study confirms that microplastics are prevalent in commercially available shellfish, representing a direct pathway for human dietary exposure.
