FDA Import Alert 99-42 — Spice detention for lead contamination
FDA enforcement mechanism for intercepting lead-contaminated spices at US ports of entry. The alert mandates detention without physical examination (DWPE) of spice shipments from countries with documented lead contamination in spice supply chains, pending analytical evidence that Pb levels are below the FDA action level of 0.1 ppm (100 ppb). Documented Pb concentrations in affected turmeric shipments have reached 2-9 ppm, 20-90 times the action level.
Key numbers
FDA action level for Pb in food: 0.1 ppm (100 ppb).
Documented Pb in affected turmeric: 2-9 ppm (2,000-9,000 ppb), 20-90x the action level.
Target countries: India, Pakistan, Bangladesh, and other countries with documented lead contamination in spice production and distribution.
Enforcement mechanism: DWPE at US ports of entry. Importers must submit analytical testing (ICP-MS or equivalent) demonstrating Pb <0.1 ppm to permit entry. Non-compliant lots refused admission or destroyed.
Active since the 1990s with periodic updates through the present.
Methods (brief)
Regulatory enforcement action under 21 U.S.C. § 342(a)(1) (adulteration). Not an analytical study.
Implications
Certification: establishes that FDA considers Pb-contaminated spices an active enforcement priority. HMT&C testing protocols for spice-containing products should reference this alert as the regulatory baseline.
Courses: demonstrates that import-level enforcement exists but is insufficient to prevent all contaminated product from reaching US retail (cf. Lech 2020, which found Pb up to 7,590 ppb in US retail turmeric despite this alert being active).
