Is Vintage Tupperware BPA-Free?
Vintage Tupperware is not BPA-free and should not be used for food prep or storage. All Tupperware manufactured since March 2010 is BPA-free and safe to use for its recommended purposes.
All new Tupperware sold anywhere in the world is BPA-free. It is recommended that owners of vintage containers manufactured before 2010 dispose of them to prevent exposure. Some people keep vintage containers for storage rather than food use. Although this limits exposure, it can still be a good idea to get rid of containers. Never use older Tupperware in the microwave; this can increase exposure to any BPA it contains.
