Vintage Tupperware ORANGE bowl: 3,380 ppm Cadmium + 935 ppm Mercury (both are extremely poisonous to humans)

Another vintage Tupperware example, orange bowl with Lid: 3,380 ppm Cadmium + 935 ppm Mercury [both are poisons for humans.]

To read details about the concern for toxicants in vintage Tupperware products, I encourage you to read my original post on the subject here (and please also read all of the comments and responses on that post for the full conversation.) Thank you! [Please also scroll down to see all of the images – which include close ups of the product numbers on the item pictured.]

When tested with an XRF instrument the bowl pictured here had the following readings:

  • Lead (Pb): Negative / Non-Detect (ND)
  • Cadmium (Cd): 3,380 +/- 26 ppm
  • Mercury (Hg): 935 +/- 15 ppm
  • Arsenic (As):  Negative / Non-Detect (ND)
  • Barium (Ba): 4,592 +/- 69 ppm
  • Chromium (Cr): 258 +/- 38 ppm
  • Zinc (Zn): 287 +/- 9 ppm
  • Copper (Cu): 19 +/- 7 ppm
  • Bismuth (Bi): 7 +/- 3 ppm
  • Vanadium (Va): 1,901 +/- 133 ppm
  • Titanium (Ti): 1,722 +/- 177 ppm

Other metals not listed were not detected with the XRF in consumer goods mode. Tests were done for a minimum of 3-minutes and confirmed multiple times. The above numbers represent one specific test results set from one single 3-minute reading (not an average of multiple tests or similar.)

Cadmium is a known carcinogen that is often found in red or orange cookware (plastic, metal, ceramic, glass). Please click this link to read more about Cadmium toxicity. The amount of Cadmium in this bowl is quite concerning (and, I think we all know how toxic Mercury is!

The consideration here is two-fold:

  1. For those who are readers on my blog and NOT Tupperware users, you may not realize that these 40-plus-year-old products are still in high-frequency regular use in homes across America. Just because they are vintage does not mean they are not in daily use today – they most definitely are, as confirmed by some of the comments (and I could have perhaps guessed, given the frankly unbelievable popularity of my original post on Facebook — which has now been shared more than 2,800 times and reached over 94,000 people in just about 24 hours [click the image here to read some of the hundreds of comments on this post on Facebook ]!
  2. It is my understanding that common lore has supported the idea that these dishes should be considered “microwave safe”, even though they are made of plastic. This means food is being heated in the dishes and that, combined with the potential use of acidic foods in these dishes gives me quite a concern for potential leaching — especially over time…in dishes that (one reader told me) came out about 1972. Specific acidic foods of concern would include lemon juice (pretty much any juice, really), vinegar, tomato sauce, soups, etc…

In response to some criticisms on my original Tupperware post:

A handful of readers had asserted their concern that the measuring cups might only test positive for toxicants as a result of contamination caused by some sort of unusual usage with toxicants. While I did not expect this to be the case (based on my experience of a decade of testing consumer goods including hundreds, and perhaps thousands of vintage plastic items) I was excited to find this set of dishes (which the bowl picture here is part of) which help to disprove that concern. These bowls are in “brand-new-never-used” condition, and were sold with a tag indicating as much (at the antique store where they were purchased), yet the toxicant levels are comparable to those found in ones that have seen normal use and wear over the years. The toxicant levels are also consistent throughout the product as there is no paint or coating – just a uniform substrate material (plastic) that makes up the entire product.

As alway, please let me know if you have any questions. I will do my best to answer them personally although it may take a while due to the increased traffic on my blog.

    Are Tupperware items that are currently being produced generally lead-free?

  2. Miranda March 11, 2019 at 9:00 pm #

    Wow! That is absolutely scary! Thank you for testing these items! <3

    Tupperware is currently tested to extremely high standards to meet the worldwide specifications required for products made and used in Europe and Japan. Not only is there not lead or arsenic found in them, they are also 100% free of BPA and Phthalates.

      Hi Krissie,

      Thank you for commenting.

      While I realize your comments are likely applicable for the new products, what we are talking about here is vintage product that is nearly 50 years old (early-1970s). The problem is that people are still using these vintage products on a daily basis.

    Is it safe to use for dry measuring only?

  5. Erika Davis March 17, 2019 at 11:24 pm #

    OMG, I used to use these (brown, orange, yellow, green) to make my lunch IN THE MICROWAVE every day at work. Who knew?? I have long since gotten rid of them, and NEVER use plastic in the microwave (actually barely ever use the microwave) anymore, but are those toxins still stored in my tissues??

      HI Erika,

      It’s hard to say, but with regular use in the way you described (hot foods/microwaved) it is much more likely a possibility than (for example) if you were just drinking water out of one of the cups on a daily basis.

      I have a post about natural chelation here that you might find interesting. I use lots of garlic in our diet (for my family and especially my children): https://tamararubin.com/2017/01/natural-chelation/

      Thank you for commenting.

    I have the orange canisters which I received as a wedding gift in 1981. I assume they are not safe. Do you know?
