"Soylent’s levels of heavy metals are entirely safe and sustainable, even for people using Soylent as a complete food substitute. Trace amounts of lead and cadmium are present everywhere, including drinking water, which is why the FDA and EPA set strict exposure limits. The FDA’s limits for lead in infant formula, which is especially stringent, is 0.5ug/mL. Our testing is done by Covance, an independent third-party lab, using the ultra sensitive and precise method ICP-MS. Testing protocols are standardized by AOAC International. Lead in Soylent 1.5 is 0.009982ug/mL, less than 1/50th of the FDA requirements for infant food. See the full certificate of analysis of Soylent 1.5 for details. The FDA does not set cadmium limits for food, but even the highest cadmium levels we have seen in testing, 21ug per serving, is thousands of times lower than the level of any observed effect in Proposition 65 toxicology data. We also test for arsenic, which at 0.7525ug per serving is well below the Proposition 65 limit. The heavy metal levels specified by California Proposition 65, which were cited in As You Sow’s press release, are much more stringent than those set by the FDA, the EPA, and the WHO. As a result, most packaged foods sold in California, as well as restaurants, coffee shops, grocery stores, convenience stores, and theme parks are required to display the warning. We are not required to change the product, but we are required to display the Proposition 65 text where we sell our products, which we do. Soylent is completely safe and 100% compliant with all national (US, Canada, and EU) and state regulations, both in labeling and in levels of heavy metals." source: http://blog.soylent.com/post/126888496882/soylent-is-compliant-with-california-proposition http://blog.soylent.com/post/126888496882/soylent-is-complia...
