PET Microplastics in Bottles Linked to Pancreatic Changes in Animal Study

A study published in BMC Genomics found that microplastics from polyethylene terephthalate (PET)—common in plastic water bottles—caused dose‑dependent changes in pig pancreatic cells, including altered protein abundance and increased fat accumulation and inflammation, suggesting potential pancreatic disruption in humans with PET exposure. While not yet proven for people, the findings add to concerns about microplastics and support policies to curb plastic usage and promote alternatives like reusable bottles.
