Microplastic particles were found in 88 percent of samples of protein foods destined for US consumers, according to a study by researchers at the Ocean Conservancy and the University of Toronto. Published in January 2024 in the journal “Environmental Pollution”, the study looked at samples from 16 different protein types, including seafood, pork, beef and chicken, as well as plant-based protein sources. Also, the study found evidence that highly processed foods, such as tofu and chicken nuggets, contained more microplastics, suggesting that food processing is a likely source of microplastic contamination. For all samples, 44 percent of microplastics identified were fibers, while 30 percent were plastic fragments.
