Ingestion and polymeric risk assessment of microplastic contamination in commercially important brachyuran crab Portunus sanguinolentus

Researchers examined microplastic contamination in a commercially important crab species from three fishing harbors in India and found plastics in every location sampled. The crabs contained an average of 0.67 microplastic particles per gram, with polyethylene and polystyrene among the most common types, and pollution levels rated as very high risk at all sites. Since these crabs are widely eaten, the findings suggest that seafood consumers may be regularly ingesting microplastics.

Microplastic pollution in wild populations of decapod crustaceans: A review

Researchers reviewed the occurrence and characteristics of microplastics found in wild populations of decapod crustaceans including crabs and shrimps. They found that fibrous microplastics smaller than 1 mm were the most commonly detected type, and that edible portions generally contained fewer microplastics than non-edible parts. The review highlights the importance of understanding microplastic contamination in commercially valuable crustaceans for both ecological and food safety assessments.

Assessing microplastic accumulation in the hepatopancreas of marine and freshwater crabs from the North-East Part of the Bay of Bengal

Researchers compared microplastic contamination in the hepatopancreas of three edible crab species from the Bay of Bengal region, including two marine species and one freshwater species. They found that the freshwater crab had the highest microplastic counts, averaging nearly four particles per sample, and identified nine different polymer types across all species. The findings raise concerns about human exposure to microplastics through seafood consumption in the region.

Plastic in the food chain: Investigating microplastic consumption by the blue-swimming crab (de Rochebrune, 1883) and shrimp (Pérez-Farfante, 1967) from an estuarine system in Ghana

Researchers found microplastics in over 90% of blue-swimming crabs and 31% of shrimp sampled from an estuary in Ghana, with polyethylene being the most common plastic type — raising public health concerns since locals eat these shellfish whole without extensive preparation.

Microplastic Abundance in Blood Cockles and Shrimps from Fishery Market, Songkhla Province, Southern Thailand

Microplastics were detected in blood cockles and shrimps purchased from a fishery market in Songkhla Province, southern Thailand, with contamination levels and polymer types characterized in commercially important seafood that represents a route of microplastic ingestion for local consumers.

Microplastics in Scylla Serrata: A baseline study from southwest India

Researchers examined microplastic contamination in the mud crab Scylla serrata from mangrove habitats on India's southwestern coast and found an average of about 29 microplastic particles per individual. Fibers were the dominant type, and polypropylene and polyethylene were the most common polymers detected. The study establishes a baseline for microplastic presence in a commercially important crab species, raising questions about potential human exposure through seafood consumption.

Microplastic Abundance in Edible Crabs and Gastropods on the Blanakan Coast

Researchers sampled water, sediment, crabs, and gastropods along the Blanakan coast of Indonesia and detected microplastics in all sample types, with fragments, films, fibers, and pellets all present — suggesting widespread contamination that poses a food safety concern for local seafood consumed by humans.

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.

First Evidence of Existence of Microplastics in Stomach of Some Commercial Fishes in the Lower Gulf of Thailand

This study provided the first evidence of microplastics in the stomach contents of commercial fish species from the lower Gulf of Thailand, finding plastic debris in multiple economically important species. The results raise food safety concerns for Thai seafood markets and highlight an understudied region in Southeast Asia's microplastic contamination landscape.

Occurrence and distribution characteristics of aged microplastics in the surface water, sediment, and crabs of the aquaculture pond in the Yangtze River Delta of China

Researchers measured microplastic contamination in crab aquaculture ponds in China, finding particles in the water, sediment, and crab tissues. The crabs' intestines contained the most microplastics, followed by gills and liver, and contamination levels increased with body weight. Since these crabs are raised for human consumption, the study shows that farmed seafood can be a direct source of microplastic exposure for people.

Assessment of microplastic contamination in clams and shrimp from estuarine environments of Goa: implications for environmental health and food safety

Researchers examined clams and shrimp from estuarine environments in Goa, India, and found microplastics present in both species and their surrounding waters, with shrimp from one site showing particularly high contamination and bioaccumulation. The particles were predominantly polyamide, polyethylene, and polystyrene fibers and fragments, likely originating from fishing, tourism, and waste disposal activities. The findings raise concerns about food safety for local and tourist populations who regularly consume seafood from these coastal areas.

Microplastic contamination in Thai vinegar crabs (Episesarma mederi), giant mudskippers (Periophthalmodon schlosseri), and their surrounding environment from the Bang Pu mangrove forests, Samut Prakan province, Thailand

Thai vinegar crabs and giant mudskippers from a mangrove forest in Thailand's inner Gulf both contained microplastics — averaging up to 16 particles per individual in crabs and 11 in mudskippers — with small fibres dominating and polyethylene and polypropylene as the most common polymers. Mangrove ecosystems act as accumulation zones for land- and sea-sourced plastic waste, and contamination of these organisms signals risk for the broader food web and for communities that consume mangrove seafood.

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.
