Is Everything Bad For Us? #3,6 & 7 plastics

April 9, 2008

So the story on the Today Show regarding the safety of plastic bottles got me thinking. Now I am not an alarmist who generally gets sucked into the notion that everything we eat, drink or touch is going to cause us to die of cancer. But this story touched a nerve with me.

The offending chemical is Polycarbonate (PC) which is composed of a hormone-disrupting chemical called bisphenol A, which has been linked to a wide variety of problems such as cancer and obesity. Additional potentially harmful affects of the stuff include fertility problems childhood behavioral problems such as hyperactivity. (sources: and )

The doctor who was on, mentioned that it’s best to try to avoid plastic bottles with the numbers 3, 6 or 7 in the little triangle found on the bottom of them. So I did a quick scan of my house and discovered that my baby bottles (Evenflo) are #7 and all of the Gerber baby food that I currently feed to the Little One and previously fed to the Big One are all #7 containers.

An article on the National Geographic Web site ( says that #7 is actually the catchall for “other” plastics.

Here’s their definition of #7 containers: “ #7 other (misc.; usually polycarbonate, or PC, but also polylactide, or PLA, plastics made from renewable resources)
Product examples: Baby bottles, some reusable water bottles, stain-resistant food-storage containers, medical storage containers”

So how in the heck am I supposed to figure out if the #7 on the Gerber baby food containers represents PC or PLA???
