Industry executives have known for decades about microplastics infiltrating the human body, according to a Los Angeles Times report. Scientists are only now beginning to understand the full extent of harm these tiny plastic bits cause. Internal company memos reveal the plastics industry has been aware of this potential contamination for at least half a century. These documents show industry scientists were concerned about microplastic particles migrating beyond the gut and depositing in organs. This knowledge could significantly impact the plastic food packaging industry.The concern dates back to a 1974 scientific meeting where a German gastroenterologist presented findings on ingested particles infiltrating the body. While overlooked by government scientists, this presentation sparked worried discussions among company scientists. A Stanford professor, Tracey Woodruff, who reviewed the documents, stated that major chemical companies knew and remained silent. She compared this inaction to other industries aware of pollutants like greenhouse gases, asbestos, and tobacco. However, a chemical industry spokesperson, Craig Davis, disputes this characterization, stating that scientific debate is not silence but rather how sound science advances. He affirmed the industry's commitment to advancing microplastics science through independent research and supportive policies.
