The increase of plastic waste in the environment, especially in seas and oceans, and the presence of microscopic particles of plastic products (microparticles and nanoparticles) has generated –apart from an environmental concern, a food safety concern, as microplastics and nanoplastics could be incorporated in the food chain and therefore be present in food intended for human consumption. Microplastics and nanoplastics are microscopic particles of plastic products less than 5 mm long, coming from the fragmentation of macroplastics that largely find their way into the aquatic environment and, due to their difficult degradation, remain the environment for decades. Microplastics and nanoplastics encompass a broad range of sizes (from 0,001 µm to 5.000 µm) and particles (fragments, pellets, pearls, fibres, foam, films), and can be composed of different kinds of plastic materials. In recent years, various studies have found microplastics in a wide range of concentrations in marine waters, wastewater, fresh water, food, the air and drinking water, both in bottled and tap water. Microplastics have also been found in human faeces. The present document reviews what are the current knowledge on the presence of microplastics and nanoplastics in the food chain and their potential effects on human health.
