Researchers assessed microplastic contamination in blue crabs (Callinectes sapidus) from Corpus Christi Bay, Texas, finding microplastics in crab stomachs and identifying fragment and fiber morphologies associated with sediment ingestion during benthic foraging. The study documents microplastic exposure in a commercially and ecologically important estuarine crustacean in the Gulf of Mexico.
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.
