Prop 65 Compliance for Salt (Lead + Cadmium + Naturally Occurring Metals)

Salt Is a High-Risk “Natural” Category

California Prop 65 applies to all food — including minerals and natural ingredients. Salt products are not exempt simply because contaminants are naturally occurring. :contentReference[oaicite:0]{index=0}

Why Salt Is at Risk

• Source contamination: sea water, rock, and brine contain native heavy metals :contentReference[oaicite:4]{index=4}
• Processing limits: refining reduces but does not eliminate metals :contentReference[oaicite:5]{index=5}
• Unrefined products: retain higher contaminant levels :contentReference[oaicite:6]{index=6}
• Daily exposure: seasoning use creates cumulative intake across meals :contentReference[oaicite:7]{index=7}

“Naturally occurring” does not eliminate Prop 65 exposure obligations.

Chemicals of Concern in Salt

• Lead — MADL 0.5 µg/day; primary enforcement driver :contentReference[oaicite:8]{index=8}
• Cadmium — MADL 4.1 µg/day; commonly co-occurring :contentReference[oaicite:9]{index=9}
• Arsenic — present in certain salt sources

Business Impact of a 60-Day Notice

• Immediate enforcement clock upon filing :contentReference[oaicite:10]{index=10}
• $20K–$100K+ settlement exposure per action :contentReference[oaicite:11]{index=11}
• Relabeling and product removal risks :contentReference[oaicite:12]{index=12}
• Retail pressure for compliance documentation :contentReference[oaicite:13]{index=13}

Most companies settle because documentation is weak—not because compliance is impossible.

The Five-Pillar Compliance Program for Salt

• Pillar 1 — Hazard Identification: source-based heavy-metal risk mapping
• Pillar 2 — Exposure Assessment: serving-size and intake calculations vs MADL
• Pillar 3 — Testing Oversight: ICP-MS heavy-metal verification at ISO 17025 labs :contentReference[oaicite:14]{index=14}
• Pillar 4 — Warning Determination: documented warn vs no-warn decisions :contentReference[oaicite:15]{index=15}
• Pillar 5 — Monitoring & Records: batch-level tracking and defensible documentation :contentReference[oaicite:16]{index=16}

Supply-Chain Compliance Control

• Supplier Attestation: declarations from all salt-source vendors :contentReference[oaicite:17]{index=17}
• Risk Mapping: classification by source type (sea, rock, brine) :contentReference[oaicite:18]{index=18}
• COA Verification: batch-level testing validation :contentReference[oaicite:19]{index=19}
• SCAR System: corrective action tracking for suppliers :contentReference[oaicite:20]{index=20}

Verification Testing — What & How Often

• Lead (ICP-MS): per lot
• Cadmium: per lot or risk-based frequency
• Arsenic: periodic or source-triggered
• Trend analysis: monthly compliance review :contentReference[oaicite:21]{index=21}
