Is Old Tupperware Safe? How to Ensure Kitchen Safety

Is Old Tupperware Safe?

Old Tupperware produced before 2010 may not be safe to use as it might contain BPA and other harmful chemicals.

However, the majority of Tupperware products made today, specifically those with plastic numbers #4 and #5, are considered safe.

It is important to note that Tupperware products with plastic number #7 may be unsafe.

Old Tupperware has been found to contain toxicants like lead, cadmium, mercury, and arsenic.

Plastic aging and wear can also cause the release of chemicals and toxins.

Furthermore, using old Tupperware with excessive heat and highly acidic foods may not be safe.

It is advisable to check the resin identification codes on the containers to determine their safety.

Repurposing or recycling old Tupperware is recommended to reduce waste, and genuine Tupperware products can be identified by their logo, code numbers, and additional letters or numbers indicating the type of lid.

Quick Tips and Facts:

1. The “burping” sound that is often associated with Tupperware is actually an ingenious design feature. The sound occurs when you close the lid and press down, causing the air inside to be forced out through a small vent, creating an airtight seal.

2. While Tupperware is generally safe to use, older Tupperware containers made before the year 2010 may contain traces of bisphenol A (BPA) in their plastic composition. BPA is a chemical compound that has been linked to various health concerns, so it’s essential to check the date of manufacture or consider upgrading to newer Tupperware models without BPA.

3. Did you know that Tupperware, or more accurately, its innovative sealable containers, played a vital role in the success of the Apollo 11 moon landing? NASA utilized Tupperware containers to collect and store lunar samples brought back to Earth by the astronauts.

4. In the late 1950s, Tupperware parties became a highly effective method for women to gain financial independence and a source of personal fulfillment. These parties fostered a sense of community and empowerment among women during a time when traditional gender roles were still prevalent.

5. The iconic Tupperware “bell” shaped containers were actually inspired by a piece of cornbread! Earl Tupper, the creator of Tupperware, observed that a piece of cornbread retained its freshness and moisture for longer when stored in a particular shape, leading to the development of the classic Tupperware bell-shaped design.

Harmful Chemicals In Old Tupperware

Old Tupperware containers produced before 2010 have raised concerns due to the presence of harmful chemicals such as Bisphenol A (BPA) and other toxins. BPA, a chemical used in the production of certain plastics, has been linked to various health issues, including hormone disruption and reproductive problems. Tupperware products manufactured today, made from plastics marked with numbers #4 and #5, are considered generally safe and less likely to contain harmful chemicals. However, it is essential to be cautious when using old Tupperware purchased before 2010.

Safety Of Modern Tupperware Products

Fortunately, the majority of Tupperware products made in recent years are considered safe for use. The company has taken steps to address the concerns regarding harmful chemicals and has shifted to using plastics marked with numbers #4 and #5, which are considered safe for food storage. These plastics are less likely to contain BPA and other toxic substances. It is important to check the bottom of the Tupperware container for the resin identification code, as it will help determine the type of plastic used. Plastics marked with numbers #2, #4, and #5 are generally safe for storing food, while plastics marked with numbers #1, #3, #6, and #7 should be avoided.

Potential Risks Of Tupperware With #7 Label

When it comes to assessing the safety of Tupperware, one key factor to consider is the resin identification code marked at the bottom of the container. Tupperware products labeled with the number #7 have raised concerns. This category encompasses different types of plastic, some of which may pose risks for food storage. Plastics marked with #7 are not likely to be Bisphenol A (BPA)-safe, indicating that they may contain this harmful chemical. Hence, it is important to exercise caution when using Tupperware products labeled with the #7 code.

Chemical Release From Aging And Wear Of Tupperware

Plastic aging and wear can lead to the release of chemicals and toxins, compromising the safety of Tupperware containers. Over time, plastics can break down, especially when exposed to heat and repeated use. This breakdown process can release harmful chemicals into the food stored in the containers. It is highly recommended to regularly inspect your Tupperware for signs of wear, such as cracks, scratches, or discoloration. If any of these signs are present, it is advisable to replace the affected containers to minimize the risk of chemical exposure.

Caution With Excessive Heat And Acidic Foods

Old Tupperware containers may not be suitable for use with excessive heat or highly acidic foods. Exposing Tupperware to high temperatures, such as in the microwave or dishwasher, can accelerate the release of harmful chemicals. Similarly, storing acidic foods, such as tomatoes or citrus fruits, in old Tupperware containers can cause the plastic to leach chemicals into the food. To ensure kitchen safety, it is advisable to follow the manufacturer’s instructions and avoid using old Tupperware with excessive heat or acidic foods.

The safety of old Tupperware containers is a valid concern. While Tupperware products made before 2010 may contain BPA and other harmful chemicals, those made after 2010 are generally considered safe, as they are made from plastics marked with numbers #4 and #5. It is important to be cautious when using Tupperware with the #7 label, as they may contain BPA and other risky substances. Additionally, old Tupperware containers may contain toxicants such as lead, cadmium, mercury, and arsenic, emphasizing the need for replacement with newer, safer options. Plastic aging and wear can also lead to the release of chemicals, making it essential to inspect Tupperware for signs of deterioration. Lastly, caution should be exercised with excessive heat and acidic foods, as these can accelerate chemical release. By staying informed and taking necessary precautions, you can ensure kitchen safety and make well-informed choices regarding the use of old and modern Tupperware containers.
