Microplastic contamination in the genus Litopenaeus: A systematic review of current evidence and future perspectives
AI summary Read the abstract
This review paper pulls together existing research on how microplastics, tiny plastic particles, are contaminating shrimp in the Litopenaeus family, a group that includes popular seafood species. Since these shrimp absorb microplastics from their environment and we eat them, this pollution could end up on our dinner plates, but the researchers note that much more direct study is needed, especially for common species like white shrimp, before we fully understand the risks to human health.
The Microplastic contamination in the genus Litopenaeus involves sources, entry routes, environmental matrices, shrimp exposure biological responses and identifies priorities for methodological standardisation and direct research on Litopenaeus, specially in L. setiferus.

Effects of microplastics and nanoplastics in shrimp: Mechanisms of plastic particle and contaminant distribution and subsequent effects after uptake
AI summary Read the abstract
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.

Microplastics weaken the exoskeletal mechanical properties of Pacific whiteleg shrimp Litopenaeus vannamei
AI summary Read the abstract
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.
