Toxic plastics
Morning,
I recently purchased Tupperware items from eBay. After looking into this product, I have found the following info:
Potential dangers of Tupperware and plastic containers include the leaching of endocrine-disrupting chemicals like BPA and phthalates into food, especially when heated, damaged, or used for fatty/acidic items. These chemicals are linked to hormonal imbalances, reproductive issues, and increased risk of certain cancers. Old, scratched, or vintage plastic poses higher risks of chemical leakage and bacterial growth.
Key Health and Safety Risks
- Chemical Leaching: Plastics can leach harmful compounds, including Bisphenol A (BPA) and phthalates, which can disrupt the endocrine system, causing hormonal imbalances and reproductive issues.
- Cancer Risks: Certain components in plastic, such as vinyl chloride, may damage DNA, potentially increasing cancer risks.
- Microplastics: Over time, plastic containers degrade and can release microplastic particles into food, which are then consumed.
- Bacterial Growth: Scratched, cracked, or warped containers can trap bacteria, making them difficult to sanitize.
- Heavy Metals in Vintage Products: Older Tupperware (pre-2010) may contain lead, arsenic, or cadmium, particularly in bright, colored items, making them unsafe for food storage.
Risk Factors and Precautions
- Heat Exposure: Microwaving or cleaning plastic in the dishwasher accelerates the degradation of plastic, causing higher levels of chemical leaching.
- Food Type: Acidic (tomato sauce, citrus) and fatty/oily foods are more likely to absorb chemicals from plastic.
- Age of Product: Older plastics are more likely to break down and release harmful substances.
General Food Safety Regulations (Chemical Migration)
- Under the Materials and Articles in Contact with Food (England) Regulations 2012 (and equivalent in Scotland/Wales), all food containers must meet strict safety standards:
- Non-toxic migration: Materials must not transfer constituents (chemicals) into food in quantities that endanger human health.
- Migration limits: There is a strict limit on the overall migration of chemicals: 60 milligrams of constituents per kilogram of food.
- Authorised Substances: Only approved monomers and additives can be used to manufacture food-contact plastics.
The bottom line are the dangers of such products and the legal status for sellers. I'd be interested in hearing comments on this.
Many thanks,
eBay user

Mentor6 months agoThis has been known about for years. I'd never microwave plastic, nor would I use it to freeze any kind of acidic (a pasta sauce with tomato, for example) product. It's just common sense, really. It's vital to consider how your food may be contaminated by modern storage products or cooking utensils.

Mentor6 months agoThis is not new news of Tupperware, which has been sold since the forties!
Some never use it, I have found it brilliant for storing items, take away picnic items, never had a problem.
It is NOT micro wave able, I'm sure some toxin would emanate if one went against those rules and placed it in a microwave!

Mentor6 months agochemicals like BPA
Tupperware specifically states that its products are BPA free.
What you have discovered isn't new - the potential for plastic products to leach chemicals or release microplastics has been well documented for years, especially when heated or abraded. Tupperware itself is not claimed to be microwave-safe unless explicitly labeled with a microwave symbol.
My advice would be simply to use common sense: avoid cheap, unbranded bargains, buy reputable, established brand products which comply with safety standards and try not to expose products to excessive heat or abrasion. Or if you're someone who is troubled by the possibility of even low-level risks, stick to glass, ceramic or stainless steel containers.
