ClearComparative analysis of microplastic pollution in commercially relevant seafood across different geographical regions
Researchers analyzed microplastic pollution in commercially important seafood species, characterizing particle morphology and polymer composition across species. The study found microplastics in all species sampled, with differences in contamination levels linked to feeding ecology and habitat.
Plastic particles in fresh and processed seafood products from Germany
This study quantified plastic particle contamination in fresh and processed seafood products sold in Germany, examining how processing affects microplastic levels in the edible portions consumers actually eat. Plastic particles were detected in both fresh and processed seafood, with processing steps influencing particle concentrations in final products.
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.
A preliminary analysis of microplastics in edible versus non-edible tissues from seafood samples.
Researchers analyzed microplastic contamination in commercially important fish and shellfish species, comparing levels in edible versus non-edible tissues. The study found microplastics present across multiple species and tissue types, providing preliminary evidence that the edible portions of seafood may contain microplastic particles, which has implications for understanding human dietary exposure.
First occurrence and composition assessment of microplastics in native mussels collected from coastal and offshore areas of the northern and central Adriatic Sea
Microplastics were detected for the first time in native mussels from coastal and offshore areas of the northern and central Adriatic Sea, with chemical analysis confirming common plastic polymers and offshore populations also affected. The study establishes a baseline for microplastic contamination in an important Mediterranean commercial shellfish species.
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.
From the ocean to our kitchen table: anthropogenic particles in the edible tissue of U.S. West Coast seafood species
Researchers quantified anthropogenic particles, including microplastics, in the edible tissue of six U.S. West Coast seafood species. The study found particles in nearly all individuals examined (180 of 182), with fibers being the dominant type at 82%, and evidence suggests that additional contamination may occur during processing from ocean to market.
The Global Spread of Microplastics: Contamination in Mussels, Clams, and Crustaceans from World Markets
Researchers used a standardized method to analyze microplastic contamination in commercially sold clams, mussels, and crustacean shellfish from markets in Belgium, Croatia, Serbia, and South Korea. Microplastics were found in about 44% of the 190 samples, with less than one particle per individual on average, and crustacean shellfish had the lowest contamination per gram of edible tissue. The type of shellfish was a stronger predictor of contamination levels than geographic origin, and the data did not support bioaccumulation with animal size.
Particle characteristics of microplastics contaminating the mussel Mytilus edulis and their surrounding environments
Researchers investigated microplastic uptake into mussels (Mytilus edulis) and their surrounding sediment and seawater at nine intertidal sites in southwest England, characterizing particle abundance, size, shape, and polymer composition across environmental compartments and mussel tissue.
Microplastics as contaminants in commercially important seafood species
This review summarizes evidence that microplastic ingestion is widespread in commercially important seafood species including mollusks, crustaceans, and fish. Evidence indicates that microplastics can affect physiology, reproductive success, and survival in marine organisms, and may also act as vectors for chemical pollutants. The study highlights the potential for human exposure to microplastics through seafood consumption, though the full health implications remain to be determined.
Microplastics in fillets of Mediterranean seafood. A risk assessment study
Researchers analyzed fillets of several common Mediterranean seafood species for microplastic contamination and estimated the associated human dietary exposure. They detected microplastics in the edible tissue of all species tested, including sardines, sea bream, and mussels. The study provides risk estimates suggesting that regular seafood consumption represents a notable pathway for human microplastic ingestion.
Plastic particles in fresh and processed seafood products from Germany
This study measured plastic particle contamination in fresh and processed seafood products from Germany, comparing levels in products that retain digestive tissues versus those where gut contents are removed during processing. Plastic particles were found in both product types, with processing influencing but not eliminating contamination in the edible seafood fraction.
Abundance and characteristics of microplastics in commercial marine fish from Malaysia
Microplastics were found in the digestive tracts of eight commercially important marine fish species caught in Malaysian waters, with prevalence and particle types varying by species and location. The study raises food safety concerns for Malaysian seafood consumers and highlights the widespread occurrence of microplastic ingestion in wild-caught fish from Southeast Asian seas.
Occurrence, abundance and characteristics of microplastics in some commercial fish of northern coasts of the Persian Gulf
Microplastics were found in muscle, liver, gill, and gastrointestinal tissues of 14 commercially fished species from the northern Persian Gulf, with gastrointestinal tissues showing the highest contamination and muscle tissue showing very low levels, suggesting limited translocation from gut to edible flesh in most species.
An examination of the occurrence and potential risks of microplastics across various shellfish
Researchers compared microplastic contamination levels in commercial shellfish from northern (Qingdao) and southern (Xiamen) China, finding microplastics in 70-100% of samples. The study assessed potential human health risks from consuming contaminated shellfish, with microplastic abundances varying across species and geographic locations.

Researchers found significant gaps in toxicological studies and inconsistencies in detection methods across different regions. The study calls for standardized analytical approaches and more interdisciplinary research to better understand and mitigate the risks of consuming microplastic-contaminated seafood.
Accumulation of microplastic in edible marine species from North Kerala, India
Researchers found microplastics in the edible tissues of three popular seafood species (clams, shrimp, and anchovies) from fish markets in Kerala, India. Fibers and fragments were the most common shapes, with polyethylene and polypropylene being the dominant plastic types. Since these species are consumed whole or with minimal processing, the study highlights a direct pathway for microplastic ingestion by people who eat locally caught seafood.
Abundance and characteristics of microplastic in some commercial species from the Persian Gulf, Iran
Scientists examined microplastic contamination in the digestive tracts of five commercially important fish and shellfish species from the Persian Gulf, finding plastic particles in nearly 73 percent of all individuals sampled.
