Study Finds Microplastics in 99% of Tested Marine Animal Flesh Samples in the US

A study published in December 2024 found that microplastic contamination is widespread in marine animal flesh consumed by humans in the US. The study sampled five types of fin fishes and pink shrimp, with 99% of the samples containing microplastics. The highest levels were found in shrimp, with 80% of the microplastics detected being fibers from clothing or textiles.

Researchers also found that microplastics can contain 16,000 different plastic chemicals and toxic compounds that can cross the brain and placental barriers. While the authors did not recommend avoiding eating marine animals due to the prevalence of microplastics in meat and produce, transitioning to a vegan diet could potentially reduce the intake of microplastics. Overall, the study highlights the need for further research and awareness concerning the impact of microplastics on marine animals and human health.
