This Miracle Rice Cooker, purchased new c. 2009 (sorry — I don’t have an exact year) used to be our personal rice cooker. We chose it because at the time, it was the only model on the market that featured a “benign” stainless steel pot (vs. aluminum — usually with some sort of nasty/toxic “non-stick coating”); it was developed and marketed as the “healthy” choice for health-conscious folks like us!
Please scroll down to see full XRF test results and a full set of images for this rice cooker. Thank you.
Nearly all of the rice cookers like this (with a similar heating unit inside the main basin) that I have tested have been positive for high levels of lead. Leaded components typically include:
1) the heating element, as with this one [note: while this component shouldn’t normally come into contact with the pot’s contents (your food), they are certainly exposed/accessible to human contact, and typically contain very high levels of lead – in the many thousand parts per million (ppm)!]
2) the pressure valves and/or safety valves in the lid [these are often either leaded brass (or alternately anodized aluminum with lead in the anodization coating formulation), and definitely DO come into contact with your food — and have poisoned children (I know first-hand of at least one documented case where the lead-poisoned child’s likely sole “mysterious” exposure was eventually traced to the family’s daily meals cooked in a pressure cooker with a leaded brass valve – that tested at over 100,000 ppm lead!)]
3) the power cord [sadly, older appliance cords – even ones from the current decade(!) – often have high levels of lead — used to treat the rubber to make it/keep it pliable]
When I found out our rice cooker’s heating element and power cord each tested positive for lead (see below)— and also discovered that the heating element on the Instant Pot (while also positive) tested with significantly lower amounts of lead, I decided to keep an eye on the Instant Pot (for vendor-promised further lowering of lead values in the heating element) and purchase one of those as a replacement for our rice cooker eventually. I just recently did that (July 2018) and here is the link with the test results for our new Instant Pot.
This old “Miracle” rice cooker is now headed to my “Museum of Lead”!
As always, please let me know if you have any questions.
