Plastic waste is a significant environmental problem, with around eight million tons of plastic waste entering the sea each year. This has led to growing concerns about the presence of plastic in seafood, specifically in fish meat. Fish eat plastic, and we eat fish, so are we also consuming plastic? The short answer is yes. Fishery products are known to be a source of microplastics in the human diet, and research has found microplastic particles in fish meat. The potential health effects of consuming these microplastics are still being studied, but there is evidence of physical damage to organs and leaching of hazardous chemicals. The presence of plastic in fish meat is a global issue, with contaminated fish found in Europe, Canada, Brazil, and China. While most plastic is found in the guts of fish, some studies have shown that microplastics can transfer to the meat, and we eat some species of small fish and shellfish whole.

What You'll Learn
Microplastics in seafood and human health
Plastic ingestion occurs across various marine organisms, including fish. While most plastic is found in the guts of fish and would typically be removed before consumption, studies have shown that microplastics can migrate from the intestines of fish to their circulatory system, surrounding tissue, and even their meat. This is particularly true for smaller particles at the nanoscale. Seafood consumption is, therefore, one pathway for human microplastic exposure.
Research has found microplastics in the blood cells of blue mussels and in the tissues of marine animals, including commercially important species. In 2011, 83% of Dublin Bay prawns and 63% of brown shrimp in the Channel and southern North Sea had ingested microplastics. A similar study found plastic in a third of UK-caught fish, including cod, haddock, mackerel, and shellfish. Another study calculated that shellfish lovers may be consuming up to 11,000 plastic fragments annually, which can accumulate in the human body over time.
The presence of microplastics in seafood is concerning due to their association with toxic chemicals from manufacturing and the surrounding environment. These chemicals, such as the hormone-disrupting bisphenol A (BPA) and pesticides, can leach from the plastics and accumulate in the tissues of marine organisms, potentially impacting human health. Initial evidence suggests that microplastics can cause physical damage to organs, compromise immune function, and impair growth and reproduction in both fish and humans.
However, the full scope of the problem is not yet fully understood. There are data gaps in microplastic research, making it challenging to assess the true extent of human exposure to microplastics through seafood consumption. While the portion of exposure from seafood is unknown, it is predicted that a top European shellfish consumer may ingest approximately 11,000 plastic particles annually. Further research is critical to address these gaps and assess the potential impacts of microplastics on human health.

Plastic pollution in oceans and its environmental impact
Plastic pollution in oceans is a pressing environmental issue that poses a significant threat to marine ecosystems, biodiversity, and the food web. It is estimated that approximately eight million metric tons of plastic enter the oceans annually, with conservative estimates suggesting that 5.25 trillion plastic particles currently circulate in ocean surface waters. This plastic pollution has far-reaching environmental impacts, affecting marine life, ecosystems, and human health.
Plastic pollution in oceans has detrimental effects on marine life, including fish, marine mammals, invertebrates, and birds. Plastic particles can cause physical damage to organisms, such as lacerations and internal injuries. Additionally, the ingestion of plastic by marine organisms can lead to suffocation, entanglement, and infections. Some studies have found that microplastics can transfer from the guts of fish to their meat, posing a potential risk to humans who consume seafood.
Microplastics, smaller plastic particles, have been detected in seafood, including fish and shellfish. These microplastics are associated with chemicals from manufacturing and the surrounding environment, raising concerns about physical and chemical toxicity. Evidence suggests that ingested microplastics can leach hazardous chemicals, such as bisphenol A (BPA) and pesticides, which can compromise immune function and affect growth and reproduction. The accumulation of these chemicals in the food chain can have potential impacts on entire ecosystems.
The presence of plastic pollution in oceans also contributes to the transportation of invasive species, further threatening marine ecosystems and biodiversity. Floating plastic debris can allow coastal organisms to spread to new environments, disrupting the delicate balance of marine ecosystems. Additionally, plastic pollution can have economic impacts, affecting sectors such as tourism, fisheries, and aquaculture.
Addressing plastic pollution in oceans requires global cooperation and collective action. Efforts to reduce plastic production, improve waste management, and promote recycling are essential to mitigating the environmental impacts of plastic pollution. Initiatives such as the UN Environment Assembly's resolution "End Plastic Pollution: towards an International legally binding instrument" are crucial steps towards tackling this pressing environmental issue.

Plastic ingestion across different taxa
Plastic ingestion is a pressing issue that affects a wide range of organisms across different taxa and trophic levels. Marine mammals, fish, invertebrates, birds, and even humans are all susceptible to ingesting plastic. The presence of plastic in the environment, an individual's acceptance threshold, and the similarity of cues given by natural foods and plastics are key factors contributing to plastic ingestion.
Marine Mammals
Marine mammals, such as whales, are vulnerable to plastic ingestion. They may mistake plastic waste for food, leading to internal injuries and impairing their ability to swim. The ingested plastic can cause physical damage and release toxic chemicals, impacting their health and reproductive capabilities.
Fish
Fish are particularly susceptible to ingesting microplastics and nanoplastics due to their small size. These particles can be mistaken for plankton or other small prey. While most plastic is found in the guts of fish, there is growing concern that microplastics may transfer to the meat of fish, especially in smaller species that are consumed whole. Contaminated fish have been found in various regions, including Europe, Canada, Brazil, and China.
Invertebrates
Invertebrates, such as crustaceans and earthworms, are also affected by plastic ingestion. For example, freshwater crustaceans called amphipods have not shown any negative effects from microplastics, possibly due to their ability to handle indigestible materials. However, other invertebrates like earthworms can transfer plastic particles up the food chain, impacting ecosystems and soil health.
Birds
Marine birds, including seabirds and megafauna, are at risk of plastic ingestion. The odour of marine plastic debris can trigger foraging behaviour in some bird species, leading to the consumption of plastic. This can result in internal injuries and impair their ability to fly.
Humans
Human exposure to microplastics through seafood consumption is a growing concern. Shellfish, in particular, pose a risk as they are often consumed whole, including species like mussels and prawns. Studies estimate that a top European shellfish consumer may ingest approximately 11,000 plastic particles annually. While the health effects of microplastics on humans are still being researched, there are concerns about potential toxicity and the accumulation of plastics and associated chemicals in the body.

Human exposure to microplastics via seafood
Plastic ingestion occurs across various taxa within different trophic levels, including marine mammals, fish, invertebrates, and even fish-eating birds. Plastic particles are often found in an organism's digestive tract, and microplastics can persist in the animal's body, moving from the intestinal tract to the circulatory system or surrounding tissue.
Seafood consumption is one pathway for human microplastic exposure. Fish and seafood represent one of the most important routes of exposure for humans through the diet, associated also with non-marine sources like honey, salt, sugar, and beer. As of 2015, global seafood intake represented 6.7% of all protein consumed and approximately 17% of animal protein consumption. Global per capita seafood consumption is over 20 kg/year, and over 90% of US seafood was imported from regions with significant waste leakage and pelagic plastic pollution.
Shellfish and other animals consumed whole pose a particular concern for human exposure. If there is toxicity, it is likely dependent on the dose, polymer type, size, surface chemistry, and hydrophobicity. Microplastics have been found to cause physical damage to organs and leach hazardous chemicals, such as bisphenol A (BPA) and pesticides, which can compromise immune function and hinder growth and reproduction.
There is insufficient information to assess the true amount of microplastics humans are exposed to via seafood. However, researchers have estimated that a top European shellfish consumer may eat approximately 11,000 plastic particles annually. The implications of this exposure are still unknown, but it is clear that human activity has led to widespread microplastic contamination throughout the marine environment, and seafood consumption represents a critical pathway for human exposure.

Potential health effects of consuming plastic-contaminated fish
Plastic waste has become a significant environmental problem, with an estimated eight million tonnes of plastic waste entering the sea each year. This has resulted in plastic ingestion by various marine organisms, including fish. Consequently, the presence of plastic in fish meat has become a growing concern, with potential health implications for consumers.
Fish and fishery products are a significant source of microplastics in the human diet. While most plastic is found in the guts of fish and is typically removed before consumption, studies have shown that microplastics can migrate from the gut to other parts of the body, including the circulatory system, muscle/meat, and surrounding tissues. This means that small fish and shellfish that are consumed whole pose a particular risk for human exposure to microplastics.
The potential health effects of consuming plastic-contaminated fish are a cause for concern. Microplastics have been found to leach hazardous chemicals, including additives used in plastic manufacturing and environmental pollutants such as pesticides. These chemicals can have toxic effects on humans, impacting hormone function, immune function, growth, and reproduction. In addition, the physical presence of microplastics in organs can cause inflammation and physical damage.
While the overall risks to human health from ingesting microplastics in fish are currently believed to be low, the limited data available makes it challenging to fully assess the potential dangers. However, as plastic production and pollution continue to increase, the prevalence of microplastics in the aquatic environment and, subsequently, in fish, is expected to rise. This underscores the importance of addressing this issue through improved waste management, extended shelf life of plastic items, and increased awareness to reduce plastic litter and its impact on the aquatic ecosystem and human health.
