Overview: Contamination Concerns
Moringa powder can absorb heavy metals from the soil (lead, cadmium, arsenic, mercury) and may be exposed to toxins during storage or processing. Most reputable brands monitor and minimize these risks.
Heavy Metals in Moringa Powder
- Lead, Cadmium, Mercury, Arsenic: Studies show most commercial moringa powders contain levels below international safety thresholds, but rare samples may exceed them if grown in contaminated soil.
- Testing: Certified organic and lab-tested powders have consistently safer profiles.
| Heavy Metal | Typical Range (mg/kg) | EU Safety Limit (mg/kg) |
|---|---|---|
| Lead | 0.001–3.285 | 0.3 |
| Cadmium | <0.182 | 0.2 |
| Mercury | 0.010–0.366 | 0.1 |
| Arsenic | <1.574 | 0.1–0.3 |
Other Contaminants: Mycotoxins & PAHs
- Mycotoxins: Mold toxins from poor storage, e.g., aflatoxins, are rare but possible. Safety limit: 10 µg/kg.
- PAHs: Can occur if dried over open fires but generally rare in certified products.
How Contamination Occurs
- Soil: Main source for heavy metals.
- Storage: Improper conditions can introduce mycotoxins.
- Processing: Drying over combustion sources may lead to PAHs.
Safety Regulations & Limits
- EU Regulation 1881/2006: Sets max levels for lead (0.3 mg/kg), cadmium (0.2 mg/kg), mercury (0.1 mg/kg), aflatoxins (10 µg/kg), and PAHs (50 µg/kg for dried herbs).
