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.
The stress-immunity axis in shellfish.
This review examines the stress-immunity relationship in shellfish, covering how environmental stressors — including chemical contaminants like microplastics — activate immune responses and affect shellfish health. Since shellfish are consumed by humans and accumulate microplastics from the water they filter, understanding how plastic pollution stresses these animals is important for seafood safety.
Potentiality of natural live food organisms in shrimp culture: A review
This paper is not about microplastics; it reviews the potential of live food organisms like microalgae as sustainable, nutrition-rich ingredients in shrimp aquaculture feed.
Immunotoxicity and oxidative damage in Litopenaeus vannamei induced by polyethylene microplastics and copper co-exposure
Researchers found that when polyethylene microplastics carrying copper were injected into white shrimp, the combined exposure was significantly more harmful than either pollutant alone. The shrimp experienced suppressed immune function, increased oxidative stress, and severe damage to muscles, liver, and gills. Since shrimp are widely consumed seafood, these findings raise questions about how microplastic-bound metals in marine environments could affect both shellfish health and food safety.
Pollution in marine bivalves: The immunosuppressive effects of microplastics on Anadara granosa
Researchers exposed blood clams to polystyrene microplastics for one week and found that the plastics suppressed their immune system in a dose-dependent manner. Higher microplastic concentrations reduced the clams' immune cell counts, hemoglobin, and disease-fighting enzymes. Since blood clams are a commercially harvested seafood species, weakened immunity could increase disease outbreaks in clam populations and potentially affect the safety of shellfish consumed by humans.
Toxicological effects of polystyrene nanoplastics on marine organisms
Researchers exposed Pacific white shrimp to polystyrene nanoplastics at various concentrations and measured immune, antioxidant, and tissue responses after seven days. They found that nanoplastic exposure disrupted immune function, increased oxidative stress, and caused tissue damage, particularly in the hepatopancreas and gills. The study adds to growing evidence that nanoplastics can harm the health of commercially important marine species.
The Eco-Immunological Relevance of the Anti-Oxidant Response in Invasive Molluscs
Not relevant to microplastics — this review examines how antioxidant defence mechanisms in invasive mollusc species help them survive environmental stress and support immune function, with no focus on microplastic exposure.
Microplastic toxicity in shrimp: From mechanistic pathways to ecological implications.
Researchers systematically reviewed 94 studies on microplastic toxicity in shrimp, mapping mechanistic pathways from particle characteristics to oxidative stress, immune dysfunction, neurotoxicity, and reproductive impairment across hepatopancreas, gills, gut, and gonad tissues, and identifying shrimp as effective bioindicators for aquatic microplastic risk assessment.
Effects 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.

Researchers surveyed microplastic contamination in dominant wild shrimp species in Haizhou Bay, China, characterizing the types, sizes, and concentrations of MPs found in their bodies and assessing the human dietary exposure risks from consuming these economically important seafood species.
Oxidative effects of consuming microplastics in different tissues of white shrimp Litopenaeus vannamei
Researchers fed white shrimp diets containing polystyrene microplastics and found the particles accumulated in gills, muscles, and the hepatopancreas. The microplastics triggered oxidative stress, DNA damage, and lipid damage in multiple tissues, along with visible tissue abnormalities including edema and immune cell infiltration. The study demonstrates that dietary microplastic exposure can cause widespread oxidative harm across different organ systems in commercially important shellfish.
Microplastics in decapod crustaceans: Accumulation, toxicity and impacts, a review
This review summarizes research on microplastic contamination in decapod crustaceans like shrimp, crabs, and lobsters, which are widely consumed as seafood. Studies have found microplastics accumulating in their gills, digestive organs, and gut, with experimental evidence showing oxidative stress, immune damage, and reproductive toxicity. The findings raise concerns about potential human exposure to microplastics through seafood consumption.
Involvement of Microplastics in the Conflict Between Host Immunity Defense and Viral Virulence: Promoting the Susceptibility of Shrimp to WSSV Infection
Researchers found that PVC microplastics made shrimp significantly more vulnerable to white spot syndrome virus, a devastating disease in aquaculture, by suppressing their immune defenses. The microplastics interacted with the virus to prolong its survival and triggered changes in the shrimp's fat metabolism that weakened a key immune signaling pathway. This study demonstrates how microplastic pollution in coastal waters could increase disease outbreaks in seafood species, potentially affecting both food supply and food safety for humans.

Microplastics weaken the exoskeletal mechanical properties of Pacific whiteleg shrimp Litopenaeus vannamei
Researchers discovered that environmentally realistic levels of microplastics weakened the shells of whiteleg shrimp by disrupting the structure of chitin, the main building material in crustacean exoskeletons. The microplastics also embedded in the shell surface and altered key genes and metabolites involved in shell formation. Since shrimp is a widely consumed seafood, this finding raises questions about both the quality of farmed shrimp and the potential for microplastic transfer to human consumers.
