Low plastic ingestion rate in Atlantic cod (Gadus morhua) from Newfoundland destined for human consumption collected through citizen science methods
AI summary Read the abstract
Researchers examined Atlantic cod from Newfoundland and found a low rate of plastic ingestion compared to studies of other species and regions, suggesting that plastic ingestion rates vary substantially by species, habitat, and local pollution levels.
Marine microplastics are a contaminant of concern because their small size allows ingestion by a wide range of marine life. Using citizen science during the Newfoundland recreational cod fishery, we sampled 205 Atlantic cod (Gadus morhua) destined for human consumption and found that 5 had eaten plastic, an ingestion prevalence rate of 2.4%. This ingestion rate for Atlantic cod is the second lowest recorded rate in the reviewed published literature (the lowest is 1.4%), and the lowest for any fish in the North Atlantic. This is the first report for plastic ingestion in fish in Newfoundland, Canada, a province dependent on fish for sustenance and livelihoods.

Low plastic ingestion rate in Atlantic Cod ( Gadus morhua ) from Newfoundland destined for human consumption collected through citizen science methods
AI summary Read the abstract
This citizen science study sampled 205 Atlantic cod destined for human consumption in Newfoundland and found that only 5 (2.4 percent) had eaten plastic — a lower ingestion rate than reported for many other fish species. The authors discuss whether cod feeding behavior or the sampling context explains this low rate and note implications for human dietary exposure.
Newfoundland destined for human consumption collected

Using citizen science during the recreational cod fishery in Newfoundland, researchers found that 2.4% of Atlantic cod sampled had eaten plastic—the second lowest ingestion rate reported in the scientific literature. This is the first documentation of plastic ingestion in fish from Newfoundland, where fisheries are economically and culturally vital.
An analysis of ingested microplastics found in offshore Atlantic cod (Gadus morhua) and inshore capelin (Mallotus villosus) using scientific and citizen science methods
AI summary Read the abstract
A study examined microplastic ingestion in offshore Atlantic cod and inshore capelin from Newfoundland, Canada, using both scientific laboratory methods and citizen science approaches. The research expands the list of North Atlantic fish species documented to ingest plastic pollution and tests the viability of community-based monitoring.
Low incidence of plastic ingestion among three fish species significant for human consumption on the island of Newfoundland, Canada
AI summary Read the abstract
This study reported the first baselines of plastic ingestion in Atlantic cod, Atlantic salmon, and capelin from Newfoundland, Canada, finding a low but nonzero frequency of plastic ingestion in these commercially important fish. The data provides a starting point for tracking future changes in microplastic exposure in North Atlantic food fish.
Plastic ingestion by Atlantic cod ( Gadus morhua ) from the Norwegian coast
AI summary Read the abstract
Researchers examined 302 Atlantic cod stomachs from six locations along the Norwegian coast and found plastic in 3% overall, but with a hotspot in Bergen City Harbour where 27% of cod contained plastic, and polyester as the most common polymer, suggesting that local urban contamination strongly influences fish exposure.
