Study warns to wash new plastic bottles or risk sneaky BPA exposure

Plastic bottles are a common sight and many people are likely to use them at some point. Hazardous plastics containing BPA have been eliminated due to their potential health impact, but the problematic chemical can still appear at times. This is according to a new study by The Ohio State University, which found that consumers should wash new plastic bottles well or risk exposure to the substance.

Many studies have linked chemical BPA to a variety of potentially harmful health impacts, including everything from significant cardiovascular changes to hormonal disorders, infertility and changes in fetal development. Because of this, the USA, Canada and Europe have several bans on the use of the substance and many companies choose BPA-free plastics for food and beverage containers.

One of those BPA-free plastics used for things like water bottles is called Tritan, but there is a chance that you will still be exposed to BPA if you buy one of these bottles. The question, according to a new study by the OSU Wexner Medical Center, is to use these bottles without washing them properly first.

Traces of BPA were discovered on some new plastic bottles sold as BPA-free in the US. Researcher Rebecca Holmes explained:

We believed that it likely was BPA contaminant on the surface of the bottle. I thought there is something here. I was thinking people are buying those bottles off the shelves, and they are taking them home and probably not washing them. They are using them so they are consuming BPA.

It seems that just rinsing the new bottle before use is not enough to remove potential BPA contamination, with the results of the study that multiple runs in a dishwasher were the ideal way to remove any traces of BPA that might remain. The researchers also noted that most of the BPA-free bottles they bought and tested were actually free of the chemical.
