Microplastics in seafood and human health risks are increasingly recognized as a critical issue. Microplastics, defined as plastic particles under 5 mm, are found in marine environments and can be ingested by marine organisms, including fish and shellfish, which are then consumed by humans. These particles can accumulate chemicals from the environment, raising concerns about their potential toxicity. Research indicates that microplastics can translocate to organs and may affect human health through ingestion. The sources of microplastics include both primary and secondary microplastics, with secondary microplastics resulting from the breakdown of larger plastic items. Microplastics can also absorb persistent organic pollutants (POPs), increasing their potential health risks. Microplastics are found in various seafood products, including invertebrates, crustaceans, and fish. Studies show that shellfish and other seafood can contain significant amounts of microplastics, which can then be ingested by humans. The presence of microplastics in seafood is a growing concern, as it may contribute to human exposure to harmful chemicals. Research suggests that microplastics can affect human health through physical and chemical pathways, including inflammation, immune system disruption, and potential toxicological effects. The health impacts of microplastics are not fully understood, but there is growing evidence of their potential to cause harm. To address these concerns, there is a need for further research to assess the health impacts of microplastics on humans and to develop mitigation strategies. Current knowledge is limited, and there is a need for standardized methods to assess microplastic exposure and its effects. Governments, industry, and civil society all have roles to play in reducing microplastic pollution. Initiatives such as beach cleanups and industry efforts to reduce plastic use are important steps in mitigating the problem. However, more research is needed to fully understand the risks and develop effective strategies to protect human health.Microplastics in seafood and human health risks are increasingly recognized as a critical issue.
