Grimaldi 2017 — Prop 65 chocolate settlement establishes tiered Pb and Cd warning triggers
This is a December 30, 2017 attorney-commentary article by Ann Grimaldi (Grimaldi Law Offices, San Francisco) summarizing the comprehensive Proposition 65 settlement reached among nine chocolate-industry settling defendants and As You Sow over lead and cadmium in chocolate products. The article documents the settlement’s tiered warning-trigger structure (cacao-percentage-stratified Pb and Cd concentrations in ppm), the immediate triggers, the year-7 automatic drop-down levels, the Expert Committee’s mandate to investigate root causes and feasibility-of-reduction, the maximum settlement payment ($210,375 for a large grinder/wholesaler), and the implicit settlement acknowledgment that lead and cadmium in chocolate are naturally occurring. The article was written in anticipation of the San Francisco Superior Court’s review hearing scheduled for February 14, 2018.
Source role
This source documents the policy framework of the 2018 California Prop 65 chocolate Consent Judgment from the contemporaneous attorney-commentary perspective at the moment the settlement was submitted for court approval. It is a C-tier secondary legal-news summary: there are no original measurements, no peer review, and no primary regulatory text — but it is a public-record description of the settling defendants, the warning-trigger ladder, the drop-down ladder, and the Expert Committee mandate. The same Pb and Cd warning-trigger tables it reproduces appear verbatim in the Expert Committee’s Final Report (see asyousow2022-expert-investigation-cocoa-chocolate-products). This source is useful as historical and regulatory-context grounding for the chocolate Pb/Cd file; the Expert Committee’s 2022 Final Report is the load-bearing technical document, not this attorney commentary.
The settling defendants identified in this article are public-record information from a regulatory event (the Prop 65 Consent Judgment): Barry Callebaut USA LLC, Blommer Chocolate Co., Cargill Inc., The Hershey Company, Lindt & Sprungli (including affiliated Ghirardelli Chocolate Company), Guittard Chocolate Company, Mars Incorporated, Mondelez International, and Nestle USA. The retailer Trader Joe’s Company was the original lawsuit defendant in San Francisco Superior Court in November 2015. Per the brand firewall (Part 12) Exception 1, these companies are named as the subject of a regulatory enforcement action, not as ranked contamination-value attributions; this source does not provide any per-manufacturer Pb or Cd concentrations.
Key numbers
The Consent Judgment defines three cacao-content product groups and two warning-trigger ladders: an immediate (year-1) ladder and an automatic drop-down (year-7) ladder. The drop-down levels apply automatically if the Expert Committee does not make alternative recommendations.
Lead warning triggers (ppm, as reproduced in Grimaldi’s table):
| Cacao percentage | Immediate Pb trigger (ppm) | Year-7 drop-down Pb (ppm) |
|---|---|---|
| Up to 65% | 0.100 | 0.065 |
| More than 65% and up to 95% | 0.150 | 0.100 |
| More than 95% | 0.225 | 0.200 |
Cadmium warning triggers (ppm, as reproduced in Grimaldi’s table):
| Cacao percentage | Immediate Cd trigger (ppm) | Year-7 drop-down Cd (ppm) |
|---|---|---|
| Up to 65% | 0.400 | 0.320 |
| More than 65% and up to 95% | 0.450 | 0.400 |
| More than 95% | 0.960 | 0.800 |
Other structural numbers reported: maximum settlement payment of 500 million); 60-day Notices of Violation issued by As You Sow beginning in 2014; lawsuit filed against Trader Joe’s Company in November 2015; San Francisco Superior Court review of the settlement set for February 14, 2018; nine settling defendants formally named in an amended complaint. The article reports that the Expert Committee operates on a consensus basis (not majority vote) and that its work is funded by the settling defendants.
Methods (brief)
This is an attorney-authored commentary article, not a primary measurement study. There are no analytical methods. The article paraphrases the proposed Consent Judgment’s structural provisions (warning triggers, drop-down ladder, Expert Committee mandate, payment structure, opt-in provision, warning text and transmittal method aligned to Prop 65 safe harbor regulations). Source dating and authorship are clearly attributed (Ann Grimaldi, dated December 30, 2017, published at grimaldilawoffices.com). The closing disclosure labels the post “attorney advertising.”
Regulatory and policy context
The article frames the settlement as injecting “some scientific discipline into the required compliance measures while establishing a new industry standard.” It explicitly notes that the settlement implicitly acknowledges Pb and Cd in chocolate are naturally occurring, and that the Expert Committee is charged with investigating both natural and anthropogenic sources alongside feasibility of reduction. Grimaldi also predicts that the opt-in provision is likely to draw additional manufacturers (and possibly retailers) into the settlement, making the warning triggers a de facto industry standard regardless of formal opt-in status.
The article anchors the settlement to the contemporaneously updated Prop 65 safe harbor regulations: the settlement specifies warning text and transmittal method that mirror those regulations, and the settling defendants gain enforcement-driven incentives to test Pb and Cd in their chocolate products on a routine basis.
Implications
Certification: Documents the Prop 65 Consent Judgment policy framework that the chocolate row’s regulatory-context input rests on. The Pb and Cd warning-trigger ladders by cacao percentage are the same ladders the Expert Committee evaluated in its 2022 Final Report; this article is the contemporaneous (2017) policy-framing record.
Courses: Useful for course modules on Prop 65 enforcement mechanics, settlement structures, and the role of expert committees in private regulatory negotiations. The cacao-percentage stratification of the warning triggers is a non-trivial regulatory design that downstream chocolate-industry compliance work has had to internalize.
App: Not directly applicable; no measurement values for consumer-app contamination estimation.
Verification notes
Settlement-trigger tables (Pb and Cd, immediate and drop-down ladders) cross-checked against the asyousow2022-expert-investigation-cocoa-chocolate-products Final Report Tables 3 and 4 reproductions and confirmed identical. Settling-defendant list reflects the article’s public-record identification of nine manufacturers; per Part 12 Exception 1, these are named as subjects of a regulatory enforcement action, not as contamination-value attributions, and no per-manufacturer values appear in this source. Court approval date in the article (“February 14, 2018”) is reported as the scheduled review date; the actual Consent Judgment effective date is documented in the Expert Committee’s downstream Final Report.
