Dear NPR/ The Salt / @NPRFood & Natalie Jacewicz,
Please make this correction on your crockpot article dated 12/8/2017:
YOU CANNOT use a home lead test kit to test a mass manufactured crock pot for lead. The limit of detection (low threshold) in the home kits is 600 ppm lead and the amount of lead in most of these crock-pots is in the 50 to 200 ppm range, below the limit of detection of the swab kits. To tell your readers to use a home test kit (on an item like this) for “peace of mind” is a waste of their money.
Please read this blog post here:
Also read all my posts about crock pot testing here:
All my testing was done with an XRF instrument, which is really the only tool to use to test for total lead content in a modern ceramic item.
Thanks for reading and checking out my links.
