Microplastic Contamination Across Bangladesh’s Aquaculture and Fisheries Value Chain: A Structured Review of Farm Inputs, Aquatic Biota, Seafood Products, Dietary Exposure, and Research Gaps

Summary

Researchers reviewed 24 studies to map out where tiny plastic particles (microplastics) show up in Bangladesh's fish and shrimp farming industry, from the water and feed used on farms to the seafood that ends up on dinner plates. The review found microplastics at multiple points along this chain, meaning people who eat fish and shrimp from these sources could be unknowingly consuming plastic particles, though more research is still needed to understand exactly how much and what that means for health. This matters because seafood is a major food source worldwide, and understanding contamination sources is a first step toward reducing our exposure to these particles.
