Antibacterial School Supplies are a Rip-Off

Experts say there's no benefit to buying school products coated with antibacterial chemicals.

avoid school supplies coated with antibacterial chemicalsStroll down the aisle of an office supply store or peruse back-to-school supply websites and you might think you're shopping for surgical ward supplies. Once reserved for hospital operating rooms, the antimicrobial chemicaltriclosan, an Environmental Protection Agency (EPA)-registered pesticide linked to hormone disruption, allergies, and thyroid problems, is now being applied to everything from pens and pencils to scissors and binders, which are marketed as being "antibacterial" or "antimicrobial" and somehow better for your children.

"We know the bulk of triclosan in the environment and most likely in the human body comes from Food and Drug Administration-approved personal care products that contain triclosan," explains Kathy Dolan, public-health policy analyst with Food & Water Watch. According to the Centers for Disease Control and Prevention, triclosan levels in humans have increased 50 percent since 2004, and it's now being detected in human breast milk. "But we don't have any research showing how much triclosan is lost from things like lunch bags, binders, and athletic clothing."

THE DETAILS: There's plenty of evidence to suggest that using triclosan is a bad idea. Aside from research showing that it damages the thyroid, researchers link the overuse of triclosan to an increase in "superbug" bacteria strains that are becoming resistant to our antibiotics.

But beyond all of those alarming health problems, here's another reason to avoid triclosan in school products: It's a rip-off. "You'll pay more [for triclosan-treated products], and there's no evidence it does any good," explains Stuart Levy, MD, president of the Alliance for the Prudent Use of Antibiotics, who notes that consumer products use one-fifth to one-tenth the amount of triclosan that hospitals use to kill germs. Dr. Levy says the concern of the scientific and infectious disease world is that such overuse of antibiotics and chemicals like triclosan is leading to an increase of mutant bacteria that could render valuable antibiotics useless.

WHAT IT MEANS: Here's the secret companies marketing Microban- and other triclosan-containing products don't want you to know: Washing your hands with regular soap and water, or using alcohol-based hand sanitizers, is safer and more effective than applying antimicrobial chemicals like triclosan to your skin. "The simple point is there's no advantage to triclosan or chemically impregnated soaps or products for the household," says Dr. Levy.

With triclosan in so many products, we're also apparently eating it. A 2010 study published in the journal Environmental Science & Technology found that the antibacterial chemicals flushed down the drain from soap and cleaners often slip past wastewater treatment plants and wind up in water and fertilizer used to grow food crops. (These fields are fertilized with human sewage sludge, a practice that is banned in organic agriculture.)
