ClearA meta-analysis of the characterisations of plastic ingested by fish globally
This meta-analysis pools data from global studies to assess what types of plastic fish most commonly ingest, finding that microfibers and small fragments dominate across both freshwater and marine species. These findings are important for human health because widespread plastic ingestion by fish means that microplastics are likely present in much of the seafood consumed around the world.
A meta-analysis of the characterisations of plastic ingested by fish globally
This meta-analysis pools data from studies worldwide to characterize the types of plastic that fish ingest, finding that small fibers and fragments are the most common forms consumed. The findings matter for human health because the same fish that swallow these microplastics are often eaten by people, creating a direct pathway for plastic particles to enter our diet.
What are the global patterns of microplastic ingestion by fish? A scientometric review
This review summarizes global research on microplastic ingestion by fish and finds that contamination is widespread across aquatic ecosystems, with fibers and fragments being the most commonly ingested shapes. The study highlights that fish higher on the food chain tend to accumulate more microplastics, which matters for human health since many of these species are commonly consumed as seafood.
Worldwide contamination of fish with microplastics: A brief global overview
A literature review from March 2019 to March 2020 synthesized worldwide data on microplastic contamination in fish, finding that a median of 60% of fish from 198 species across 24 countries contained microplastics in their organs. Carnivorous species ingested more microplastics than herbivores, consistent with trophic transfer and bioaccumulation through food webs.
Microplastic contamination in wild freshwater fish: Global trends, challenges and perspectives
This global review analyzed 144 studies on microplastic contamination in wild freshwater fish across 45 countries and found that 450 fish species were contaminated, including 35 species on the conservation Red List. Microplastics were most commonly found in the gastrointestinal tract, with fibers and fragments being the dominant shapes. The evidence indicates that freshwater fish worldwide are widely exposed to microplastic pollution, with potential implications for both aquatic ecosystems and human seafood consumption.
Occurrence and Impacts of Microplastics in Freshwater Fish
This review summarizes research on microplastic occurrence in freshwater fish across multiple regions, examining ingestion rates, polymer types, and potential health effects. The authors highlight that freshwater fish are widely exposed to microplastics and call for more standardized monitoring to assess risks to fish and to people who eat them.
Microplastics in Fish: A Comprehensive Review
This review synthesizes research on microplastics in fish, covering contamination sources, detection methods, and impacts on wild and farmed populations globally — and examining how plastic particles in fish tissues may transfer to humans through seafood consumption.
Global meta‐analysis reveals diverse effects of microplastics on freshwater and marine fishes
This systematic review and meta-analysis examines the effects of microplastics on fish in both freshwater and ocean environments. The findings show that microplastics reduce feeding, impair digestion, slow growth, and weaken immune function in fish, which is concerning because contaminated fish are a major food source for people worldwide.
A Meta-Analysis of the Characterisations of Plastic Ingested by Fish Globally
This meta-analysis examined what types of plastic fish are swallowing around the world. The findings show that fish most commonly ingest tiny microplastic fibers and fragments smaller than 1 millimeter. Since many of these fish species end up on our plates, this research raises important questions about how much microplastic we may be consuming through our seafood diet.
A Systematic Review on Microplastic Contamination in Fishes of Asia: Polymeric Risk Assessment and Future Prospectives
This systematic review found widespread microplastic contamination in freshwater and saltwater fish across Asia, with polyethylene and polypropylene being the most common plastic types. Since fish is a major protein source for billions of people, this contamination represents a direct pathway for microplastics to enter the human diet.
The occurrence and consequences of microplastics and nanoplastics in fish gastrointestinal tract
This review examines the occurrence and consequences of microplastics and nanoplastics in fish gastrointestinal tracts across numerous species, focusing on bioaccumulation implications for human seafood consumers. Researchers found widespread microplastic ingestion documented in fish globally, raising concern given that seafood provides over 20% of dietary protein for approximately 1.4 billion people representing 19% of the global population.
Occurrence of microplastics (MPs) in the gastrointestinal tract of fishes: A global systematic review and meta-analysis and meta-regression
Fish globally averaged 2.76 microplastic particles per gastrointestinal tract, with fish from enclosed water bodies (lakes, estuaries) containing 2-4x more than those from open oceans, and fish from low-income economies harboring 5.5x more microplastics than those from high-income economies.
A review of microplastic pollution in commercial fish for human consumption
This review examined microplastic contamination in commercial fish muscle consumed by humans worldwide. Researchers found that microplastics were present in 56.5% of the fish samples analyzed, with contamination levels ranging from 0.016 to 6.06 items per gram of muscle tissue, raising concerns about long-term dietary exposure to microplastics through seafood consumption.
Microplastic occurrence in 21 coastal marine fish species from fishing communities on Viti Levu, Fiji
Researchers analyzed microplastic ingestion in 184 fish from 21 species across three coastal communities in Fiji and found microplastics in 74% of fish examined. Fibers were the most common particle type at 66%, with polyethylene and polypropylene the dominant polymers. This dataset, the largest of its kind for Fiji, establishes a critical baseline for monitoring plastic pollution in the region's coastal fishing grounds.
Threats of Microplastic Pollution on Fishes and its Implications on Human Health (Review Article)
This review summarizes research from 2010 to 2023 on microplastic contamination in fish and its potential implications for human health. Researchers found that microplastics are ingested by fish across diverse aquatic environments, with particles accumulating in the gastrointestinal tract and other tissues. The study highlights concerns that microplastic-contaminated seafood may represent a pathway for human exposure to both the plastic particles and associated chemical pollutants.
Geographical and ecological factors affect microplastic body burden in marine fish at global scale
This systematic review analyzed microplastic levels found in marine fish worldwide and identified key factors driving contamination. Fish from areas with heavy human activity contained more microplastics, and since many of these species are eaten by people, this contamination represents a direct route of human exposure through seafood.
Bioavailability and toxicity of microplastics to fish species: A review
This review summarizes current knowledge about microplastic ingestion and its toxic effects in fish species worldwide. Researchers found that microplastics have been detected in fish from nearly all types of aquatic habitats, and both field and laboratory studies confirm fish are highly susceptible to ingesting these particles. The study notes that microplastics alone or combined with other pollutants can cause various health problems in fish, raising concerns about implications for human seafood consumption.

Assessment of microplastic contamination in commercially available fishes
Researchers found microplastics in every one of 32 commercially sold fish from markets in Vellore, India, recovering a total of 875 particles from their gills and digestive tracts. Fibers made up 91% of the microplastics, with polyvinyl alcohol and polyethylene being the most common types. Since these are fish commonly eaten by local populations, the findings raise direct concerns about human microplastic exposure through seafood consumption.
Abundance, characteristics, and risk assessment of microplastics in indigenous freshwater fishes of India
Researchers examined microplastic contamination in five widely consumed freshwater fish species from India and found plastic particles in all specimens, with fibers being the most dominant type. Evidence of microplastics in edible fish tissue indicates translocation from the gut, suggesting a pathway for human exposure through consumption. Risk assessment showed that while microplastic abundance posed a low quantitative risk, the polymer types identified indicated a high hazard potential for the fish species studied.
