Below is an EXPANDING list of products (foods, supplements, and cosmetics) that have tested “non-detect” for Lead, Mercury, Cadmium, and Arsenic with independent, third-party, community-funded laboratory testing coordinated by Lead Safe Mama, LLC (an Oregon-based small business with a unique community-collaborative business model and a focus on consumer goods safety and childhood Lead poisoning prevention). These examples clearly demonstrate that it is possible to manufacture safer choices. We have not yet found a safer choice for a matcha product, although there is a safer choice for a green tea product in the list below.

Key Points to Consider:

• There are almost no reasonable safety limits proposed for toxicant contamination (heavy metal contamination specifically) of foods and supplements consumed by adults (or by the general population) in the United States.
• Any available proposed safety thresholds (and guidance) for foods and supplements consumed by adults are not currently set at levels that are protective of human health, given practical/ actual consumption patterns of foods (vs. manufacturer-defined serving sizes).
  • The above point is especially important given children (and pregnant women) eat all foods, not just foods marketed for consumption by children (for example: Find me a pre-teen that won’t go through an entire 5-ounce/ 5-serving bag of potato chips in one sitting)!
• Our focus is (as always) on the health of children.
• By applying the standards proposed by the Baby Food Safety Act of 2021 to all foods and supplements, we are working more in line with standards that protect human health (for all!) given all scientific and medical experts agree there is no safe level of Lead exposure for human beings. Those Action Levels are:
  • 5 ppb Lead
  • 5 ppb Cadmium
  • 2 ppb Mercury
  • 10 ppb Arsenic
• Said another way: You would never be eating a snack chip out of a bag and say to your 5-year-old child “this product is only marketed for consumption by adults, so you cannot eat it.” That would be ridiculous. Kids eat what we eat (and products consumed by pregnant women impact their developing babies), so everything that goes into our bodies in an attempt to nourish us and support our health and well being should be appropriate for any age consumer (not just a demographic designated by the manufacturer based on irrelevant age group-related toxicity standards for a specific product or ingredient).
• Remember: There is no safe level of Lead exposure for human beings. Period.
  • This is a non-negotiable point that everyone in the scientific and medical community — everyone who researches Lead poisoning — agrees with.
