Microplastics pose significant safety concerns, from everyday kitchen items like cutting boards to commonly used single-use plastics such as water bottles and takeout containers. Beyond the well-known environmental damage caused by single-use plastics, experts are increasingly concerned about potential health risks associated with their consumption.
Wendy Petta, whose TikTok video detailing her transition away from single-use plastics garnered nearly half a million views, exemplifies a growing movement. She explained to ABC News that she began replacing single-use containers with glass storage containers and canning jars. Dr. Stephanie Widmer, an emergency medicine physician and toxicologist, clarified that the danger often stems from misuse. “The idea that single-use plastics are dangerous comes from simply not using it as directed,” she stated, emphasizing their intended single-use nature.
Research indicates that reheating certain single-use containers in microwaves can leach chemicals into food, and prolonged use increases microplastic exposure. Furthermore, studies suggest that washing some thicker plastics in a hot dishwasher cycle may also be hazardous. Dr. Widmer noted that some evidence suggests black containers may leach more chemicals than others, but stressed that more research is needed to confirm this.
In response to these concerns, California is enacting legislation to reduce single-use plastic packaging by 25% by 2032, mandating recyclability or compostability. The European Union has implemented even stricter measures, outright banning certain single-use plastics when viable alternatives exist.
Despite growing concerns, Dr. Widmer acknowledged the lack of concrete evidence definitively linking single-use plastics to negative health impacts. She emphasized that the current body of evidence is still developing and requires further research. The plastics industry association similarly stated their commitment to ensuring plastic remains a safe and responsible choice for its intended applications.
