Researchers reviewed 61 studies on microplastic contamination in bivalve mollusks worldwide, finding that these filter-feeding shellfish consistently contain microplastics regardless of location. The study found significant differences in contamination levels between bivalve families based on their habitats, suggesting that both water-dwelling and sediment-dwelling species can be used to monitor different types of microplastic pollution. The authors call for standardized sampling and analysis protocols to enable meaningful comparisons across future studies.
Comparative analysis of microplastic pollution in commercially relevant seafood across different geographical regions
This study compared microplastic contamination across commercially relevant seafood species commonly consumed in the European market, characterizing both the morphological and chemical properties of particles found in edible tissue. Results showed widespread but variable contamination across species, with polymer types and particle abundance differing by species and tissue type.
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 of microplastics in store-bought fresh and processed clams in Italy
Researchers measured microplastic occurrence in store-bought fresh and processed clam products in Italy, detecting particles in all examined products and finding higher concentrations in minimally processed compared to heavily processed clams.
Microplastics in the edible tissues of shellfishes sold for human consumption
Researchers analyzed the edible tissues of four shellfish species sold for human consumption and found microplastics present in all samples examined. Fibers were the most commonly detected particle type, with polymer identification confirming synthetic origins including polyethylene and polypropylene. The findings raise concerns about human dietary exposure to microplastics through commercially available seafood products.
Overviewing the Ground Reality of Microplastic Effects on Seafoods, Including Fish, Shrimps and Crabs: Future Research Directions

The authors assess implications for food safety and call for standardized monitoring and risk thresholds for microplastics in seafood.
Dietary exposure to microplastic via shellfish and the importance of the edible shellfish tissue measurements
This study highlighted shellfish as a major source of human dietary exposure to micro- and nanoplastics, emphasizing the need for standardized analytical methods to enable comparable exposure assessments and risk characterizations across different countries and shellfish species.
Presence of Microplastics in Four Types of Shellfish Purchased at Fish Markets in Okayama City, Japan.
Scientists found microplastics in all four types of shellfish—oysters, clams, scallops, and mussels—purchased from fish markets in Okayama, Japan. The findings confirm that people who eat shellfish regularly ingest microplastics, raising questions about potential health impacts from this dietary exposure.
A systematic review on microplastic contamination in marine Crustacea and Mollusca of Asia: Current scenario, concentration, characterization, polymeric risk assessment, and future Prospectives
This systematic review documented microplastic contamination in shellfish and crustaceans across Asia, finding 79 species affected. Since these seafood species are widely consumed, the presence of microplastics — especially polyethylene and polypropylene — in their tissues represents a direct route of human exposure through diet.
Assessment and Analysis of Microplastics in Commercially Sold Bivalves from Los Baños, Laguna, and Lipa, Batangas, Philippines
Researchers extracted and characterized microplastics from three commercially sold bivalve species (green mussel, Manila clam, and freshwater clam) purchased at Philippine markets, finding contamination ranging from 0.52 to 2.94 microplastic particles per gram fresh weight with fibers being the most common type.
