BPA Questions

Lately, I’ve been receiving numerous questions about which plastics contain BPA and which do not. I’d like to address some general tips about determining which plastics are BPA free.

1. Check labels. Just as you check labels for salt, sugar and fat content, check the bottoms of plastic food containers for the resin code (number within the recycle symbol). Those plastic containers most likely to contain BPA are #3, 6 & 7. (Read more info about plastic resin codes here.) Also, check tags on products designed to be used with food such as coffee makers, plastic storage containers, blenders, coffee grinders, microwave ovens, etc. Oftentimes, these products will include a tag or label that designates the item as “BPA free.” If it doesn’t explicitly state that it is BPA free, then I’d suggest buy another brand.

2. No resin codes. Older plastic food containers such as those from Tupperware, Rubbermaid and others may not have a resin code on the bottom. Tupperware has included an informative page on their website indicating which product lines are specifically BPA free. Contact the company/manufacturer directly if you’re unsure of BPA content. I use older Tupperware containers to hold non-food items since they are not recycle-friendly.

3. Plastics to avoid. BPA (biphensol-A) commonly found in plastic food containers, packaging, household products and other plastic items is more harmful if used in plastic food containers. Avoid any plastic product that is used with food to lessen your exposure to this harmful chemical. Do not heat plastic containers in the microwave or use food containers that have scratches; these could potentially leach BPA into your food as well.
