ClearSpatial occurrence and effects of microplastic ingestion on the deep-water shrimp Aristeus antennatus
Researchers found that 39% of deep-water shrimp (Aristeus antennatus) sampled across the Mediterranean contained microplastics in their stomachs, with ingestion rates reaching 100% near Barcelona, and that microfibers were likely retained long-term due to stomach morphology — though no measurable effects on the shrimps' physical condition were detected.
Microplastics in shrimps: a study from the trawling grounds of north eastern part of Arabian Sea
Researchers examined three species of shrimp from trawling grounds in the Arabian Sea and found microplastics in every individual tested, with an average of nearly seven particles per shrimp. Fibers were the most common type of microplastic found, and six different plastic polymers were identified in the shrimps' digestive tracts. The findings confirm that microplastic contamination is widespread in commercially important seafood species, raising questions about potential transfer to human consumers.
Evidence of Marine Microplastics in Commercially Harvested Seafood
Researchers assessed microplastic contamination in three commercially available shrimp species purchased from supermarkets in South Australia.

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.
Comparative assessment of microplastic ingestion among deep sea decapods: Distribution analysis in Sardinian and Catalan waters
Researchers examined microplastic ingestion in four species of deep-sea shrimp and lobster from the Mediterranean Sea, finding that nearly 73% of the animals had consumed microplastics. Fiber-shaped microplastics were by far the most common type found, and contamination levels varied between species and regions. The study shows that even deep-sea crustaceans consumed by humans are exposed to significant microplastic pollution.
Microplastic contamination in brown shrimp (Crangon crangon, Linnaeus 1758) from coastal waters of the Southern North Sea and Channel area
Researchers examined brown shrimp caught from the North Sea and found microplastics in their digestive tracts, documenting contamination in a commercially important crustacean consumed widely by humans in northern Europe.
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.
Abundance and ecological risk of microplastics in commercial fish species from northeastern Mediterranean Sea
Researchers examined nine commercially important fish species from the northeastern Mediterranean Sea and found microplastics in both their digestive tracts and gills. The most common particles were small polyethylene and polypropylene fibers, and bottom-dwelling fish species had higher contamination levels. While the ecological risk was rated low to medium, the presence of microplastics in widely consumed fish species highlights a potential pathway for human exposure through seafood.
Assessment of microplastic contamination in shrimps from the Bay of Bengal and associated human health risk
Researchers analyzed microplastic contamination in seven shrimp species from the Bay of Bengal and found plastic particles in every species tested, with most particles smaller than 100 micrometers. The study calculated that women in Bangladesh face a higher health risk than men from eating contaminated shrimp, highlighting how seafood can be a direct pathway for microplastic exposure in human diets.
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.
Detection of microplastic fibers tangle in deep-water rose shrimp (Parapenaeus longirostris, Lucas, 1846) in the northeastern Mediterranean Sea
Researchers detected microplastic fibers — at an average of 18.8 particles per individual — in 100% of deep-water rose shrimp sampled from two sites in the northeastern Mediterranean, indicating pervasive microplastic contamination even in deep-sea commercial crustaceans.
