Cell-cultivated aquatic food products: emerging production systems for seafood
This review examines cell-cultivated seafood, a new approach to producing fish protein by growing fish cells in a lab rather than catching or farming fish. One potential benefit is avoiding the microplastic contamination found in wild and farmed fish, since the production environment can be controlled. As concerns grow about microplastics accumulating in seafood, lab-grown alternatives could offer a way to reduce human exposure to microplastics through diet.
Polystyrene nanoplastics in the marine mussel Mytilus galloprovincialis.

Short-term exposure to polystyrene microplastics hampers the cellular function of gills in the Mediterranean mussel Mytilus galloprovincialis
Even short-term exposure (72 hours) to polystyrene microplastics disrupted gill function in Mediterranean mussels, a species commonly eaten by humans. The microplastics accumulated in gill tissue and caused metabolic disorders including changes in energy production, nerve signaling, and salt balance, along with oxidative stress. Since mussels are filter feeders that concentrate microplastics from seawater, these findings raise questions about the quality of shellfish as human food.
Microplastics stunt fish growth and alter behavior
