Summary
Researchers tested multiple types of canned seafood and found microplastic contamination in every single product examined, with an average of 3.5 particles per can. Octopus in tomato sauce and tuna in olive oil had the highest contamination levels, and polyester fibers were the most common type found. This study identifies canned seafood as yet another pathway through which people are regularly consuming microplastics, with contamination potentially introduced during the processing and canning stages.
There is limited research on the occurrence of microplastics (MPs) in canned seafood. All types of canned seafood investigated in the present study were contaminated. After sample digestion in 30 % hydrogen peroxide, a total of 40 MPs were recovered. Fibers were the most common type, blue was the dominant colour, and Fourier Transform Infrared Spectroscopy (FTIR) identified polyester as the most common polymer. Considering all samples, an average of 3.5 ± 5.2 MPs/can was obtained, with octopus in tomato sauce and tuna in olive oil presenting the highest contamination (5.2 ± 7.5 MPs/can and 5.2 ± 5.1 MPs/can, respectively). Also, significant differences between the number of MPs in the seafood tissues and immersion liquids were verified. The present study demonstrates MPs occurrence in canned seafood, a potential contamination pathway for humans. More research on the different stages of the canning processing is vital for understanding MPs contamination in cans.
