Germ Phobia Vs. Chemical Phobia

Advertising campaigns and a few well-meaning journalists for years persuaded Americans that our homes, offices and bodies are teeming with bacteria and therefore, to be safe, we should use lots of antibacterial chemicals. Now we have growing evidence that triclosan — one of the main antibacterials chemicals incorporated into soaps, cosmetics, cookware, yoga mats and other sporting equipment, mouthwash, and toothpaste — is unsafe as well. In animal experiments it is implicated in gut inflammation, colon cancer and hormone disruption.

There’s only one rational way out of this bind: to think about safety not as a black or white issue, but to consider risk-benefit ratios. After a conversation on this with epidemiologist Sander Greenland of UCLA, I started noticing that news coverage rarely considers risk this way. It’s all focused on whether this or that substance is “safe.”
