Do not reuse plastic water bottles. They may be breeding grounds for bacteria. Plastic water bottles may contain BPA. While there is concern BPA may cause birth defects, interfere with male hormones, and may cause infertility. Still, the effects of BPA on humans is currently unknown, and it is not scientifically verifiable if it is unsafe. A study shows that there is more bacteria on a reused plastic bottle that a toilet seat. Bacteria and viruses on a toilet seat cause human illness.

Key Takeaways:

• While recycling plastic items is a laudable goal, re-filling your used water bottle is not a good idea.
• Plastic bottles can harbor bacteria and leach potentially toxic chemicals.
• BPA, a chemical found in plastic bottles, might prove a factor in breast cancer, heart disease and genital birth defects.

“In particular, there have been concerns about Bisphenol A (BPA) – a controversial chemical, which is used in the manufacture of plastics and is thought to interfere with sex hormones.”
