The Harm In Reusing Plastic Bottles

It’s not the plastic chemicals you should be worried about, but what is the harm in reusing disposable plastic bottles?

It’s actually something much more mundane: bacteria. If left unwashed, any water bottle can harbor microbes—a 2002 study in the Canadian Journal of Public Health found that 65 percent of elementary students’ personal water bottles contained bacteria levels that exceeded health guidelines, for example. But disposable water bottles are particularly hospitable to them.

That’s because whereas reusable bottles are designed to hold up to repeated refillings, disposable bottles tend to break down—and that leaves room for bacteria to camp out. As the authors of a 2007 article in Practical Gastroenterology put it, “…everyday wear and tear from repeated washings and reuse can lead to physical breakdown of the plastic, such as visible thinning or cracks.

Bacteria can harbor in the cracks, posing a health risk.
