Bazie et al. 2022 - trace metals in raw foodstuffs in Burkina Faso
Bazie and coauthors analyzed metallic trace elements in major raw foodstuffs in Burkina Faso, including peanuts. The source is routeable to peanuts and broader foodstuff context because it reports 222 samples and evaluates Cd, Pb, Cr, Ni and other metals. The paper is market/jurisdiction-specific and should not be pooled into US benchmark distributions without a documented cross-market rationale.
Key numbers
- n=222 food samples were analyzed by atomic absorption spectrometry.
- Foodstuffs included rice, maize, peanut, tomato, and dried fish.
- The abstract reports Fe median 68.80 mg/kg in dried fish, 43.09 mg/kg in maize, and 28.92 mg/kg in peanuts.
- Rates above Codex Pb maximum limit were 77.95% for tomato, 66.66% for maize, and 32.5% for rice.
- Cd exceedance rates were 47.6% for maize, 71.16% for tomato, and 0% for rice.
Methods (brief)
Atomic absorption spectrometry was used for nine metallic trace elements. Health risk assessment followed the USEPA model.
Implications
Certification: Burkina Faso market context for peanuts and other raw foodstuffs. Courses: example of exceedance-rate reporting by commodity. App: supports jurisdiction-aware raw-food risk flags.

Verification notes
The PDF abstract provides sample count, matrices, method, and selected medians/exceedance rates. Commodity-specific peanut Cd/Pb table values need extraction before standards pooling.
