Microplastics Studied in Farmed and Natural Sourced Fish

According to the abstract of a study published November 19, 2020 in the journal Environmental Science and Pollution Research by researchers in Columbia and China “… the prevalence of microplastics (MPs) in freshwater fish from farmed and natural sources was investigated … Of the particles identified, fragments were the predominant type in the three tissue types (stomach, gill, and flesh) … Not all fish contained MPs …

Overall, polyethylene terephthalate (PET), polyester (PES), and polyethylene (PE) were the prevalent MPs found … A broader variety of polymer types was observed in farmed fish. The edible flesh part of fish presented the lower prevalence of MPs compared to gill and stomach (gut), with gut displaying a higher frequency and diversity of MPs. This preliminary study suggests that the incidence and type of MPs varies in farmed verses natural fish sources as well as across different tissue types, with significantly less detected within the edible flesh tissues compared with stomach and gill tissues …” #MicroPlastics #PlasticWaste #FarmedFish
