Stan Pac Longmont (Colorado) Dairy Farm Reusable Glass Milk Bottle: 38,500 ppm Lead in the black paint.
Introduction:
Tamara Rubin is an independent advocate for consumer goods safety and she is also a mother of Lead-poisoned children. She began testing consumer goods for toxicants in 2009 and was the parent-advocate responsible for finding Lead in the popular fidget spinner toys in 2017. She uses XRF testing (a scientific method used by the Consumer Product Safety Commission) to test consumer goods for contaminants including Lead, Cadmium, Mercury and Arsenic.

XRF test results from the painted decorative elements (& branding) on the glass milk bottle pictured:
- Lead (Pb): 38,500 +/- 1,400 ppm
- Cadmium (Cd): 751 +/- 57 ppm
- Chromium (Cr): 35,200 +/- 2,000 ppm
- Zinc (Zn): 109 +/- 48 ppm
- Mercury (Hg): Non-detect
- Barium (Ba): Non-detect
- Antimony (Sb): Non-detect
- Selenium (Se): Non-detect
How much Lead is “too much” Lead?
For context, the amount of Lead that is considered unsafe in an item intended for use by children is anything 90 ppm Lead or higher in the paint, glaze or coating of an item or anything 100 ppm Lead or higher in the substrate. Modern dishes and glassware are not considered to be “items intended for use by children” and so fall outside of the concern for Lead in consumer goods (and the potential impact on children.)

As always, thank you for reading and for sharing these posts. Please let me know if you have any questions and I will do my best to answer them personally as soon as I have a moment.

After reading this I decided to test the milk I get from another Colorado dairy, Morning Fresh Dairy Farm (also Stan Pac glass) and the paint was positive for lead. I’m going to test my parents Longmont Dairy bottles too (I saw the email claiming the lead was removed but I want to be sure). I heard you were looking for someone to send you a bottle so you could re-test. Do you still need one?
