Key Finding

Independent, third-party laboratory testing of Redmond Real Salt Ancient Sea Salt ("Mined in America") confirmed levels of Lead (290 ppb) and Arsenic that exceed safe thresholds proposed by the scientific and medical communities under the Baby Food Safety Act of 2021. The proposed Action Level for Lead in food is 5 ppb — Redmond Real Salt tested at 58× that threshold.

Understanding "Action Levels"

Action Level ≠ Maximum Allowable Level. Once a heavy metal in food reaches the Action Level, it enters the range that can cause lasting harm — especially to children.
These levels were proposed by the Baby Food Safety Act of 2021, which was never passed into law, but remain scientifically and medically valid benchmarks.
The Action Level concept is analogous to the American Academy of Pediatrics' 1 ppb threshold for Lead in water — even though the FDA's official level is 15 ppb. Read more about safe Lead levels in water.
Action Levels represent concentrations that are both achievable by manufacturers and protective of infant/toddler health.

Why Dismissive Arguments Don't Hold Up

Common counterarguments ("it's naturally occurring," "you only eat a little salt," "fruits have similar Lead") are addressed and refuted:

There is no safe level of Lead exposure. Period.
There is no safe form of Lead. Period.
Modern fresh fruits and vegetables do not typically contain Lead levels anywhere near those found in this salt.
Lead bioaccumulates in the body over a lifetime of chronic exposure. Read more about Lead bioaccumulation.
Safer, lower-Lead salt alternatives do exist, making the contamination in this product avoidable.
Daily chronic exposure to Lead at these levels is linked to: heart disease, kidney failure, infertility, arthritis, memory impairment, and birth complications.
Consumers would choose a safer product if properly informed — making the company's dismissive statements harmful.

Possible Sources of Contamination

Mining processes: Explosives used in mining often contain traces of Lead. Lead-painted equipment and Leaded brass components may also contaminate extracted salt.
Underground Lead deposits: Lead naturally co-exists underground with other minerals and may be present in the Redmond mines depending on depth.
Utah soil Arsenic: XRF testing of Utah soil by Lead Safe Mama confirmed elevated Arsenic levels in the Great Salt Lake area, suggesting a natural geological source for the Arsenic contamination.
Crucially: "Natural" does not mean "safe." The current levels of Lead and Arsenic found are harmful despite being legally permitted.

Greenwashing: Misleading Marketing Claims by Redmond

"Safe from modern pollutants" — Lead is a modern pollutant and is demonstrably present in the product.
"PURE and unprocessed" — A product containing Lead and Arsenic at unsafe levels cannot be considered pure.
"For everyday use" — Daily use of a Lead-contaminated product creates precisely the chronic, cumulative exposure that causes long-term harm.
"Subtly sweet flavor" — Lead often tastes sweet; the contamination may be contributing to the flavor described in Redmond's own marketing.
"Beneficial trace minerals" — The author has written two articles debunking this claim:
- The Myth of Beneficial Trace Minerals in Mined Salts (Dec 2023)
- You'd Need a Lethal Amount of Salt to Benefit From Trace Minerals (Dec 2023)

Safer Salt Alternatives

The author recommends Jacobsen Salt Co. Pure Kosher Oregon Sea Salt as the cleanest salt independently tested to date. See Jacobsen Salt lab results here.

Recommendations

Do not consume mined salt (e.g., Himalayan, Real Salt, Celtic/gray salt).
Do not consume salt harvested in clay beds.
Limit added salt in general — modern diets already contain far more sodium than is needed.
Choose a non-mined sea salt confirmed low in toxicants via independent, third-party laboratory testing.
