Good idea to wash your water bottles in the dishwater before using

UC professor interviewed about contaminated BPA-free drinking bottles

Hong-Sheng Wang, PhD, professor in the UC Department of Pharmacology and Systems Physiology, answered questions from about his latest research study. It shows that some Tritan water bottles, ones made of a plastic that is not based on Bisphenol A (BPA), were found to have transient BPA release. Such release is likely due to surface contamination, possibly during the manufacturing process.

“While most Tritan water bottles are indeed BPA free, some may have BPA contamination,” Wang told “If you are concerned about such contamination, washing the bottles thoroughly before first use is a good idea. Before washing your bottles in a dishwasher, you should check whether the bottles are dishwasher safe and follow manufacturer’s instruction.”
