There are six important signs to look for when determining if food storage containers can be washed and put away or need to head to the recycle pile. Scratches or Cracks: If a container is scratched or cracked, it's time to toss it. Cracks can jeopardize the integrity of the container and foster harmful bacteria.
If it's more than 11 years old: If the Tupperware you have at home is excessively old, you should replace it not only because it may have deep scratches from constant use where bacteria can get trapped, but also because it's probably made of bisphenol-A (BPA), a potentially harmful chemical.
While there is no set timeframe for replacing plastic food containers, experts say they should be tossed out when they show visible wear, chips, cracks, or signs of stains and odors. In place of plastic containers, experts recommend opting for glass or stainless steel instead.

Containers made before 2010 may contain BPA, a chemical associated with potential health risks. It is advised to check the manufacturing date of Tupperware containers.

“However, if products are used incorrectly and get damaged, or you see signs of chipping, breakage, peeling, warping, or leaks, you should replace them.”
