MicroplasticDistribution Patterns in Fish and Implicationsfor Safe Consumption
Summary
This study examined microplastic distribution across 1,075 fish from 37 species and identified that MP concentration was highest in the digestive tract and gills, providing practical guidance on which fish parts consumers should avoid or remove to reduce human MP exposure through seafood consumption.
Microplastics (MPs) are widely distributed in the ocean and can be ingested by fish. Despite fish being a major source of aquatic protein for humans, no study has yet addressed how to reduce the risk of human exposure to MPs when consuming fish. This study investigated 1,075 fish from 37 species across representative fishing areas, and the presence of MPs in various tissues, such as the gills, guts, and muscles, was analyzed to assess fish food safety comprehensively. MPs (particles >20 μm in size) were detected in 36.28% of the gills and 39.63% of the guts but were not detected in muscle tissues. Compared with those from deeper waters, the fish from upper layers presented greater MP abundances and smaller average sizes. A significant negative correlation was detected between the abundance of MPs in fish and their length and weight. The global per capita MP consumption from captured fish, including all tissues and muscles, is approximately 5.60 × 104 items/year. To minimize dietary exposure to MPs, humans should prioritize consuming only fish muscle and selecting fish from deeper waters and larger sizes whenever possible. Future efforts to optimize fish consumption patterns should involve systematically evaluating the combined risks of MPs and other pollutants, considering both the nutritional value and health benefits of fish consumption and adopting sustainable fishery management approaches.

Microplastic Distribution Patterns in Fish and Implications for Safe Consumption
Researchers examined over 1,000 fish from 37 species and found microplastics in the gills and guts of about 36-40% of fish, but none in muscle tissue. Fish from shallower waters and smaller fish had more microplastics. The study recommends that people eat only the muscle portion of fish and choose larger fish from deeper waters to reduce their microplastic intake, estimating that global per capita exposure from fish is about 56,000 particles per year.
How to reduce human microplastic exposure risks through optimized consumption choices of fish from seawater?
Researchers analyzed microplastics in gills, intestines, and muscle of 1,075 fish from 37 species across multiple Chinese fishing areas to assess which tissues and species pose lowest dietary exposure risk. Removing gills and intestines before consumption reduced plastic intake significantly, and certain species and fishing areas had markedly lower contamination, providing practical guidance for reducing dietary microplastic exposure from seafood.
Occurrence, distribution and characteristics of microplastics in gastrointestinal tract and gills of commercial marine fish from Malaysia
Researchers examined 158 commercial marine fish from 16 species in Malaysia and found microplastics in the gastrointestinal tracts and gills of all species studied. Fibers were the most common microplastic type, and the contamination levels varied between sampling locations. The findings add to growing evidence that microplastics are widespread in commercially important fish species, raising questions about the potential for human exposure through seafood consumption.
Microplastic contamination in some popular seafood fish species from the northern Bay of Bengal and possible consumer risk assessment
Researchers analyzed three popular seafood fish species from the Bay of Bengal and found microplastics in their gills, digestive tracts, and importantly, their muscle tissue, which is the part people eat. The presence of microplastics in fish muscle means the particles have been absorbed into body tissues, creating direct exposure for consumers. The study estimated human health risks from eating these contaminated fish and found that smaller fish tended to have higher microplastic levels.
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.
