In a groundbreaking investigation led by scientists at the University of Toronto and Ocean Conservancy, it has been revealed that a staggering 90% of various protein sources, including meat and plant-based alternatives, are tainted with microscopic plastic particles associated with severe health issues, such as cancer. This discovery follows closely on the heels of a separate study exposing bottled water as a carrier of toxic nanoparticles.
The comprehensive research involved scrutinizing 16 distinct protein sources, ranging from traditional options like chicken nuggets and beef steaks to seafood and trendy plant-based burgers. Shockingly, the findings indicate that 90% of these products contained microplastics, introducing potential health risks that are not yet fully understood. Even plant-based alternatives, often perceived as a healthier choice, were not exempt from contamination, although they exhibited lower plastic content. Notably, two plant-based samples showed 40 and 25 rubber particles, respectively.
Microplastics, existing in nano- or microscopic forms, have been associated with an array of health concerns, encompassing cancer, heart disease, dementia, and fertility problems. The study revealed a particularly alarming case wherein a top sirloin steak contained an astounding 90 rubber particles. Dr. Britta Baechler, a co-author of the study, emphasizes that the plastic pollution crisis is a pervasive issue affecting individuals across dietary choices, necessitating immediate action to curb its impact.
While the exact pathways of microplastics entering the food supply remain unclear, researchers speculate that contamination may occur during various stages of the food production and distribution chain, including packaging, ingredient addition, and exposure to airborne particles. The study underscores the urgency of further research to comprehend the extent of the issue and identify the primary sources of these microplastics.
For this study, protein and plant-based samples were procured from two supermarkets in Portland, Oregon. The samples, including seafood and plant-based proteins, underwent a meticulous 24-hour breakdown and were soaked in a detergent solution to eliminate remaining fatty material. The researchers then scrutinized 124 randomly selected samples to ascertain the quantity and type of microplastics present.
Consumption of microplastics has been associated with inflammation, cell and tissue damage, and exacerbation of symptoms related to irritable bowel syndrome (IBS). Despite recognizing the need for additional research to fully comprehend the scope of the issue, the existing information raises significant concerns about the potential impact of microplastics on human health.
