Cast Aluminum Strikes Again (I have never tested a plug-in waffle iron that was negative for Lead)

A reader sent us this waffle iron for testing.

  • All the plug-in electric waffle irons I have tested over the yearsand there have been more than 100 examples, from many different brands — have tested positive for Lead on the food surface.
  • The reason for this is that the waffle grid (the food surface of the unit) is made of cast aluminum — a manufacturing process that results in an aluminum substrate, which is typically contaminated with Lead, by the way it is produced.
  • The Lead-contaminated cast aluminum surface in waffle irons is typically covered with a Lead-free (FDA-compliant) coating (usually a coating with a titanium dioxide-based “ceramic” colorant — especially if the coating is gray, white, beige, or other light colors).
  • These coatings typically present a problem as the coating wears down and/or is chipped, scratched, or otherwise compromised — both because the titanium dioxide-based coating (which in itself can cause health impacts if ingested) might wear into your food, and also because the wearing of the coating exposes the Lead-contaminated substrate below the coating, making it possible for the Lead contaminated surface to come into direct contact with food being prepared in the appliance.
  • In addition to the Lead in the cast aluminum substrates, the older non-stick coatings used on VINTAGE (meaning 20-years-old, or older) electric waffle irons can also contain Lead themselves. In addition to the coatings, and the substrates, the electrical cords of vintage appliances usually contain high amounts of Lead — typically in the 3,000 to 10,000 ppm range (with the Lead used both to make the rubber wiring coating more pliable and sometimes also used as an industry-claimed “increased flame-retardancy treatment”).

How much Lead is “too much” Lead?

  • Modern items (newly-manufactured items made today) intended for use by children legally must not have Lead levels in the substrate higher than 100 ppm.
  • Cookware (including waffle irons) is not considered within the class of “items intended for use by children,” and is therefore not regulated in the same way.
  • As a result, even though children can be expected to regularly use items like waffle irons (perhaps even with greater frequency than the adults in the household might use them!), the (quite high) levels of Lead (over 500 ppm, in this case) typically found are currently completely legal.

Beyond the classification loophole, the industry’s argumentation to the FDA is that the coatings used are “separating” the Lead-contaminated base metal surface from the food prepared in the appliance. The FDA’s regulations do not take into account the fact that — despite the frequent absurd advertising claims — all of the coatings typically wear (with normal use, as intended). The industry also officially considers these items to be something that will be replaced in 5 to 10 years; so they are not regulated based on concerns that might come up with long-term use (and the predictable deterioration with such use).

As a solution to this issue, I recommend using an old-fashioned stove-top (non-electric) waffle iron — made of plain uncoated/unpainted cast iron. With proper care (and a little practice), a properly seasoned high quality cast iron waffle iron will perform like a champ — achieving its own very serviceable, nontoxicnaturally “non-stick” quality. (Ask your grandmother!) I have a few modern examples of these listed on my shopping website (http://www.ShopLeadSafeMama.com) on the “breakfast gear” page.

  1. How about Greenlife Ceramic Waffle and Sandwich maker. I’m thinking about getting that one. Does that one contain lead? Thank you!

    1. i have tested examples from greenlife – you can look that up using the search bar. i have not tested their waffle iron.

  2. We have been using what I would call an antique waffle iron, circa 1930 (with a new cord). Have you tested anything that old?
    Thank you.

  3. Hi Tamara, appreciate all your hard work. Donated to your website to keep it going! Have you tested pizzelles/Belgium cookies cast aluminum maker from C. Palmer Manufacturing? Bought one 10 years ago thinking its safe without nonstick coating but now realizing cast aluminum can have lead thru your website. The company has not responded to my email which makes me suspect, ugh!
    Thanks.
