“Plastic food storage containers should be replaced every six months to one year, depending on usage and wear and tear. Over time, plastic containers can become scratched, stained, or damaged, and that starts to pose a food safety risk, explains Dragomir Markovic, food scientist and founder of Wise Intake.
“However, if products are used incorrectly and get damaged, or you see signs of chipping, breakage, peeling, warping, or leaks, you should replace them.”
As much as possible, try to recycle your containers, to the extent that is possible, and they cannot be reused by someone else. But typically, unless you've got a full set in extremely good condition, it is not worth your time to try to sell these, at least in my experience. So consider donating them.
Old Tupperware, especially those over a decade old, might contain hazardous chemicals like cadmium, lead, and arsenic. These can leach into your food, posing significant health risks. Vintage Tupperware products are particularly concerning due to the potential leaching of additional harmful substances.
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.
“If you notice any discoloration, odor, or a change in taste when using the container, it should be replaced as soon as possible.
Not only does old Tupperware go bad—meaning it's not just a matter of decluttering, but decontaminating your eating rituals—but in general, storing food in plastic isn't the best idea.

Since March 2010, items Tupperware sells in the US and Canada are BPA-free, according to its website.

We often simply throw plastics away into the recycling bin, however, due to the material properties of plastics, not all can be recycled. About 75% of global plastics produced are thermoplastics that can be melted and molded over and over to produce new plastics, which – in theory – makes all thermoplastics recyclable.
Avoid products made from polystyrene (PS #6).
Found in styrofoam food trays, disposable cups and bowls, carry-out containers, and opaque plastic cutlery, polystyrene can leach styrene, a neurotoxin and possible carcinogen.

You can either go with diluted bleach (1 cup of bleach per 4 liters of water) or undiluted white vinegar. Don't worry about diluting the white vinegar. As we mentioned earlier, mold is a persistent pest, and vinegar needs its full acidic strength.
Scrub mold off hard surfaces with detergent and water, and dry completely. Absorbent or porous materials, such as ceiling tiles and carpet, may have to be thrown away if they become moldy.
Generally speaking, you'll want to throw them away after a few months to reduce the risk of bacterial build-up or leaching plastic. "The end result (of reusing them) is an increased intake of compounds that disrupt the endocrine system over time," says Le.
One way to tell the age of an item? Look at its colors: pieces from the 1940s and '50s are white or pastel, while later items are saturated in bright hues.
Exposure to BPA is a concern because of the possible health effects on the brain and prostate gland of fetuses, infants and children. It can also affect children's behavior. Additional research suggests a possible link between BPA and increased blood pressure, type 2 diabetes and cardiovascular disease.
When glass is left in the natural environment, it is less likely to cause pollution than plastic. Unlike plastics, which break down into microplastics that can leach into our soils and water, glass is non-toxic.
