Since these fish are widely consumed by people in the region, the findings highlight a direct dietary exposure pathway for microplastics to reach humans through seafood.
Toxic tuna tales: Tracing microplastic pathways in mackerel tuna (Euthynnus affinis), longtail tuna (Thunnus tonggol), and bullet tuna (Auxis rochei)
Researchers examined 125 tuna from three species in Malaysian waters and found microplastics in their digestive tracts, gills, and edible muscle tissue. Fibers were the most common type, and male fish accumulated more microplastics than females. Since tuna is one of the most widely consumed fish globally, the presence of microplastics in edible muscle tissue raises direct concerns about human exposure through seafood.
Microplastics in the edible and inedible tissues of pelagic fishes sold for human consumption in Kerala, India
Researchers examined microplastics in both edible and inedible tissues of nine commercially important fish species from Kerala, India. They found that 41% of fish had microplastics in inedible tissues like gills and viscera, while 7% had particles in edible muscle and skin, with filter-feeding fish showing higher contamination than visual predators. The study suggests that human consumption of pelagic fish from this region could result in microplastic exposure, though the quantities found in edible tissues were relatively small.

Microplastics Ingestion by Skipjack tuna (Katsuwonus pelamis) in Ternate, North Maluku - Indonesia
Researchers found microplastics in the digestive tracts of skipjack tuna collected from Indonesian waters, with plastic particles present in most fish examined. Since tuna is widely consumed, the findings raise concerns about human exposure to microplastics through seafood.
Environmental and ecological risk of microplastics in the surface waters and gastrointestinal tract of skipjack tuna (Katsuwonus pelamis) around the Lakshadweep Islands, India
This study assessed microplastic contamination in surface waters and the gastrointestinal tracts of skipjack tuna around the Lakshadweep Islands, India. Researchers found widespread microplastic presence in both environmental and biological samples, indicating that even remote oceanic island ecosystems are affected by plastic pollution.
Microplastic contamination in thirty commercially important fish species: Distribution, polymer composition, pollution indices, and human health risks
Researchers examined microplastic contamination in 600 specimens across 30 commercially important fish species from the Indian coast, finding the highest accumulation in the gastrointestinal tract with carnivorous species carrying the greatest burden. Polyethylene and polypropylene fibers were the dominant particle types, and human health risk assessment showed measurable daily intake from consuming these fish, with pollution indices indicating considerable to medium hazard risk levels.
Assessment Of Microplastics In Commercially Important Fishes Collected From Thondi Fish Landing Center
Researchers assessed the presence and characteristics of microplastics in commercially important fish species collected from the Thondi fish landing center in India. The study evaluated microplastic contamination levels in fish obtained from a coastal fishing hub, contributing data on the prevalence of plastic particles in seafood relevant to both ecological and human dietary exposure concerns.
Ecological risk assessment of microplastics and mesoplastics in six common fishes from the Bay of Bengal Coast
Researchers found microplastics in the digestive tracts and muscle tissue of six commonly eaten fish species from the Bay of Bengal, with fiber-shaped particles making up over 95% of what was found. This contamination in edible fish muscle tissue means that people who eat these species are likely ingesting microplastics directly.
Microplastic presence in dried and fresh fish from seafood markets in Sri Lanka
Scientists examined both fresh and dried fish from seafood markets across Sri Lanka and found microplastics in over 82% of the samples, with fiber-shaped pieces making up more than 95% of the contamination. Fresh fish had higher contamination levels than dried fish, suggesting that preparation methods affect microplastic content. Since these small fish species are commonly eaten whole, consumers may be ingesting significant amounts of microplastics through popular seafood products.
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.
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.
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.
Accumulation, tissue distribution, health hazard of microplastics in a commercially important cat fish, Silonia silondia from a tropical large-scale estuary
Researchers found microplastics in the digestive tract, gills, and edible muscle tissue of a commercially important catfish species from a major tropical estuary.
