ClearInvestigation of the Storage Temperature Effect on Phthalate Migration Potential in Vacuum‐Packed Fish Fillets
Vacuum-packed rainbow trout fillets stored at refrigerator and freezer temperatures for three months were found to accumulate phthalate plasticizers that migrated from the packaging material, with the chemical composition of the packaging itself changing over time with temperature. The study highlights that plastic food packaging is an active source of chemical exposure for consumers, not just a passive container, and that storage conditions matter for how much contamination occurs.
Thermal processing implications on microplastics in rainbow trout fillet
This study tested whether sous-vide cooking of rainbow trout fillets at different temperatures and durations affects microplastic abundance or migration into the fish. Results showed thermal processing altered the physical state of microplastics present in the fillets and influenced estimates of human microplastic intake from cooked fish.
Assessment of potential health risk from microplastic contamination in packaged frozen seafood
Researchers analyzed six types of packaged frozen seafood and found microplastics in all samples, totaling 421 particles predominantly composed of PTFE, PVC, and PVA polymers. Risk assessment revealed that European pilchard and saithe posed the highest potential exposure, varying with regional consumption patterns. The findings highlight the need for better monitoring and safer packaging practices across the frozen seafood supply chain.
Microplastics in vacuum packages of frozen and glazed icefish (Neosalanx spp.): A freshwater fish intended for human consumption
Microplastics were detected in vacuum-packaged frozen icefish sold in Italian supermarkets and imported from China, representing one of the first reports of microplastic contamination in a freshwater-origin food product and suggesting packaging as a potential contamination pathway.
Microplastics in the aquatic environment: implications for post-harvest fish quality
This review examined how microplastic accumulation in aquatic environments threatens post-harvest fish quality, discussing how plastic particles and associated chemical contaminants in fish gut tissue raise food safety concerns and can affect consumer acceptance.
Assessment on Microplastics Contamination in Freshwater Fish: a Case Study of the Ubolratana Reservoir, Thailand
Researchers examined microplastic contamination in freshwater fish from the Ubolratana Reservoir, Thailand, finding that 96.4% of 14 examined species had ingested microplastics, and assessed abundance, size, colour, and shape of particles from stomach and intestinal contents across sampling stations.
Abundance, composition, and potential intake of microplastics in canned fish
Researchers examined canned tuna and mackerel products for microplastic contamination and found plastic particles present in all samples tested. Fibers were the most common particle type, and polymer analysis identified materials consistent with packaging components. The study estimates potential human microplastic intake from canned fish consumption and highlights the need for further investigation into how processing and packaging contribute to seafood contamination.
Recent Study of Separation and Identification of Micro- and Nanoplastics for Aquatic Products
This review synthesizes recent findings on the occurrence, separation, and identification of micro- and nanoplastics in aquatic food products, covering their physical and chemical properties, carrier and chemical effects, seasonal and spatial variability, and analytical methods relevant to food safety assessment.
Effect of biological and environmental factors on microplastic ingestion of commercial fish species
Researchers analyzed microplastic ingestion in commercially important fish species, evaluating how biological and environmental factors influence ingestion rates across 2,222 individual fish. The study assessed gastrointestinal tract contents to determine the extent and patterns of microplastic contamination. The findings suggest that both species-specific biology and environmental conditions play important roles in determining microplastic ingestion levels in commercial fish.
Size Matters: Ingestion of Relatively Large Microplastics Contaminated with Environmental Pollutants Posed Little Risk for Fish Health and Fillet Quality
Rainbow trout were fed polystyrene microplastics (100–400 μm) contaminated with sewage or harbor effluent for 4 weeks, with liver biomarkers showing no significant oxidative stress and the fillet showing no change in oxidative stability during ice storage. The study concludes that ingestion of environmentally-sized contaminated microplastics poses little risk to fish health or meat quality under realistic exposure conditions.
Shelf-Life and Quality of Anchovies (Engraulis encrasicolus) Refrigerated Using Different Packaging Materials
This paper is not about microplastics; it compares the shelf-life of anchovies packaged in organic materials (coconut fiber, paper) versus conventional polystyrene as part of an effort to reduce plastic packaging in fisheries.
Correlation of Water Quality with Microplastic Exposure Prevalence in Tilapia (Oreochromis niloticus)
Researchers exposed tilapia to polyethylene microplastics at three concentrations and assessed effects on water quality and microplastic accumulation in gastrointestinal, liver, gill, and gonad tissues, finding that higher concentrations were associated with elevated microplastic prevalence and tissue-specific accumulation patterns.
Fish species, habitat, and capture location outweigh fish mass as drivers of microplastic pollution in Canadian Arctic fishes
Researchers investigated microplastic contamination in 435 stomachs and gastrointestinal tracts of seven freshwater fish species from the Canadian Arctic. The study found that fish species, habitat type, and capture location were more important drivers of microplastic levels than fish size, with demersal species and those near larger human populations containing significantly more microplastics.
Effects of Packaging Material Type, Storage Time and Lipid Content on Phthalate Migration in Smoked Fish Meat
Researchers investigated phthalate migration from six different plastic packaging materials into smoked fish over varying storage times and lipid contents. The study found that packaging type, storage duration, and fat content of the product all influenced the level of phthalate transfer into the food.
Comparative study on microplastic abundance in fish organs from marine and freshwater ecosystems of the southern Baltic Sea region: influence of habitat zone and feeding preferences
Researchers found microplastics in 58% of 500 fish specimens examined across Baltic Sea and northern Polish freshwater ecosystems, with carnivorous and benthic species showing the highest contamination levels and blue fibers being the most common particle type across all habitats.
[The assessment of the consumption of food packaged in plastic containers].
This study assessed the consumption of foods packaged in plastic containers and the associated risk of microplastic (MP) ingestion. It found that MP contamination of packaged water, milk, fish, and seafood contributes substantially to total daily human MP intake.
Screening for microplastics in sediment, water, marine invertebrates and fish: Method development and microplastic accumulation
Researchers developed improved methods for extracting microplastics from biological samples and sediments, using enzymatic digestion that achieved 97% particle recovery without damaging the plastics. When applied to field samples from the North Sea and Swedish coast, they found microplastics in 8 of 9 invertebrate species tested and in 68% of brown trout. Mussel tissue contained roughly a thousand times more microplastic particles per kilogram than surrounding sediment or water.
Quantification of microplastic in fillet and organs of farmed and wild salmonids- a comparison of methods for detection and quantification
Three analytical methods were compared for detecting microplastics in salmon tissue, and all three found low but measurable concentrations. The study highlights both the promise and limitations of current methods, underscoring the need for standardization to accurately assess how much plastic consumers ingest through farmed and wild salmon.
