ClearEffects of microplastics and nanoplastics in shrimp: Mechanisms of plastic particle and contaminant distribution and subsequent effects after uptake
This review summarizes how microplastics and nanoplastics affect shrimp, which are an important food source for humans. The tiny plastic particles can carry harmful chemicals and pathogens into shrimp tissue, which then move up the food chain when people eat contaminated seafood. The findings highlight concerns about plastic pollution in aquaculture and its indirect effects on human health through the food we eat.
A critical review of microplastics in the shrimp farming environment: Incidence, characteristics, effects, and a first mass balance model
This review provides the first mass balance model for tracking how microplastics flow through shrimp farming systems, from water and feed inputs to accumulation in shrimp tissues and sediments. Researchers found that microplastics can act as carriers for other contaminants and accumulate in shrimp at levels that may pose risks to consumers. The study identifies critical knowledge gaps in understanding how aquaculture practices contribute to microplastic contamination in farmed seafood.
The occurrence of pollutants in organisms and water of inland mariculture systems: Shrimp aquaculture is a procession of Microplastics accumulation
This study examined microplastic contamination in water and shrimp at different stages of both pond-based and industrial inland aquaculture systems, finding that shrimp accumulated microplastics throughout the production cycle. The results establish shrimp aquaculture as a notable pathway for microplastic transfer into the food supply.

Evidence of Marine Microplastics in Commercially Harvested Seafood
Researchers assessed microplastic contamination in three commercially available shrimp species purchased from supermarkets in South Australia. They found microplastics present in the digestive tracts of all species examined, with fibers being the most commonly identified type. The findings suggest that commercially harvested seafood represents a potential pathway for human dietary exposure to microplastics.
Assessing the impact of microplastics and nanoplastics on shrimp growth, physiology, antioxidant, immune responses and gut microbiota
This review examines how microplastics and nanoplastics affect shrimp health, covering impacts on growth, immune function, gut bacteria, and antioxidant defenses. Researchers found that plastic exposure can impair shrimp physiology through multiple pathways, with implications for both aquaculture productivity and seafood safety. The study highlights the need for more research on how plastic pollution in coastal waters threatens shrimp populations that are important for both ecosystems and human nutrition.
Ingestion and adherence of microplastics by estuarine mysid shrimp
Researchers investigated how estuarine mysid shrimp ingest and accumulate microplastics both internally and on their external body surfaces. The study found microplastics in the shrimp's bodies and fecal pellets, and feeding experiments revealed that these organisms readily consume plastic particles, raising concerns about microplastic transfer through marine food webs.
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.
Microplastic ingestion and retention in penaeid shrimp from the Arabian Sea
Researchers examined the digestive tracts of four commercially harvested shrimp species from the Arabian Sea coast of India and found microplastics in all four, including fibers, pellets, spheres, and fragments made of polyethylene, polystyrene, and other common plastics — providing baseline contamination data for an important seafood source.
Microplastic Contamination in Shrimps from the Negombo Lagoon—Sri Lanka
Researchers analyzed microplastic contamination in two species of shrimp from Sri Lanka's Negombo Lagoon, examining both gastrointestinal tracts and gills. The study found microplastics present in all sampled shrimp, raising concerns about human dietary exposure to microplastics through seafood consumption in coastal communities.
Occurrence and human exposure risk of microplastics in commercially important shrimp species from Northeastern Mediterranean Sea
Researchers examined three commercially important shrimp species from the Northeastern Mediterranean Sea and found microplastics in their digestive organs, primarily polyethylene and polypropylene fibers smaller than 500 micrometers. Smaller shrimp tended to have more ingested microplastics relative to their body weight. The study estimates that people who regularly eat these shrimp could be consuming hundreds of microplastic particles per year, highlighting the need for protective measures.
Silent Invaders: A Review of Microplastic Accumulation and Its Impacts on Marine Commercial Invertebrates
This review examines microplastic accumulation in marine commercial invertebrates -- including shellfish, crustaceans, and echinoderms -- documenting pathways of ingestion, bioaccumulation, and associated toxic effects throughout the marine food web. The authors assess the threat posed to economically important seafood species and human consumers given the ubiquitous presence of microplastics from surface waters to deep-sea sediments.
