Research has highlighted the widespread presence and potential biological impacts of microplastics. Laboratory studies on mice demonstrated that exposure to polyethylene microplastics, which are commonly used in food packaging, can trigger fatty liver disease by affecting fat metabolism and tissue repair mechanisms.

Concurrently, studies have identified significant microplastic prevalence in various seafood species. Research indicates high concentrations in shrimp, bivalve mollusks such as clams and oysters, and various fish. Bivalves are particularly susceptible due to their water-filtering feeding habits. While the ingestion of these plastics through the food chain poses potential risks to human health, including oxidative stress or impacts on the gut microbiota, experts suggest these risks do not necessitate the total removal of seafood from diets.
