Plastic fish food. Concept image of a fish cut in half with a knife and spilling microplastics from within. The image is intended to illustrate the problem of pollution of the oceans by plastic garbage. We are eating plastic on our seafood. Contaminated fish and shellfish have been found everywhere from Europe, Canada and Brazil to China ? and plastic-eating fish are now showing up in supermarkets. While most plastic has been found in the guts of fish, and would therefore be removed before eating, some studies have warned that microplastics, particularly at the nanoscale, could transfer from the guts to the meat (and, of course, we eat some species of small fish and shellfish whole). There is growing concern about toxins leaching ? laboratory tests have shown that chemicals associated with microplastics can concentrate in the tissues of marine animals. Some commercially important species have seen the majority of their population affected. It confirmed that contamination has been recorded in tens of thousands of organisms and more than 100 species. Last year, the European Food Safety Authority called for urgent research, citing increasing concern for human health and food safety given the potential for microplastic pollution in edible tissues of commercial fish.
