Heavy Metals in Spices: A Persistent Problem
Heavy metals such as lead, cadmium, and arsenic are naturally occurring elements that can enter the food supply through contaminated soil, water, and agricultural practices. Spices are particularly susceptible to this contamination because they are grown in diverse regions globally and processed using various methods. In some countries, environmental pollution and historic agricultural practices can lead to higher soil concentrations of these metals, which are then absorbed by the plants. Even organic farming, which avoids synthetic pesticides, does not protect against heavy metal uptake from contaminated soil. This makes independent testing and transparency from manufacturers essential for consumer safety.
The Simply Organic Heavy Metal Controversy
Simply Organic, a brand owned by Frontier Co-op, has been a trusted name in the organic food market for years, but recent findings have complicated its reputation regarding heavy metals. The situation is not black and white, and understanding the nuances requires looking at different test results and consumer reports over time.
In 2021, Consumer Reports conducted a large-scale test of 126 herbs and spices from 38 brands. Their report indicated that Simply Organic was among the brands with the lowest levels of heavy metals in several products tested, including basil and turmeric. However, this positive finding does not reflect the entire brand's portfolio or account for more recent developments.
More recently, some Simply Organic products, specifically certain cinnamon varieties, have been flagged for higher levels of heavy metals, leading to California Proposition 65 warnings. A specific laboratory report from October 2024 showed that Simply Organic cinnamon sticks tested positive for both lead and cadmium. The California Prop 65 warning is a legal requirement for products sold in California that contain chemicals known to cause cancer, birth defects, or other reproductive harm. The presence of this warning on certain Simply Organic products highlights a potential risk that was not as apparent in earlier testing.
Simply Organic vs. Other Spice Brands on Heavy Metals
To put Simply Organic's standing into perspective, it's useful to compare its heavy metal profile with other brands based on publicly available data. The level of heavy metal contamination varies significantly by brand, product type, and sourcing location.
| Brand | Heavy Metal Findings (Source) | California Prop 65 Warning? | 
|---|---|---|
| Simply Organic | Low levels in some products (Consumer Reports 2021); higher levels and Prop 65 warning on cinnamon variants (Pretty Organic Girl, Lead Safe Mama 2024) | Yes, on certain cinnamon products | 
| 365 by Whole Foods Market | Low levels in some cinnamon products, no Prop 65 warning cited | No, on cited products | 
| McCormick | Among the lowest levels in 2021 CR tests; lead detected in some cinnamon varieties in 2024 CR tests | Varies by product; company monitors environmental conditions | 
| Morton & Bassett | Consistently low levels in multiple CR tests | Not commonly reported | 
| Penzeys | Some cinnamon products contained lead in 2024 CR tests | Varies by product; company tests raw materials | 
| Badia Spices | Class-action lawsuit filed in 2025 over elevated lead levels found by NY Department of Ag. | Lawsuits indicate warnings may be warranted or previously missing | 
This comparison shows that heavy metal contamination is a broad industry issue, not one limited to a single brand. The variation in Simply Organic's results over time and across product types suggests that sourcing and testing are critical variables.
Simply Organic's Response and Consumer Action
Simply Organic, through its parent company Frontier Co-op, states that it conducts comprehensive in-house inspections and additional product testing for every shipment of incoming material to ensure safety. They also claim to follow internationally recognized testing standards. Despite these reassurances, the conflicting reports highlight the need for greater transparency. Consumer advocacy groups argue that brands should publish third-party lab test results (Certificates of Analysis or COAs) to allow consumers to verify heavy metal levels for themselves.
For concerned consumers, proactive steps are essential:
- Diversify your spices: Rotating between different spice brands and types can help minimize cumulative exposure to heavy metals.
- Prioritize low-risk spices: Some spices, like black pepper and garlic powder, tend to have lower heavy metal levels, while others, like cinnamon, turmeric, thyme, and oregano, often show higher levels across many brands.
- Look for clear labeling: Check product pages and labels for information on heavy metal testing or links to COAs. The presence of a California Prop 65 warning is also a key indicator to consider.
- Grow your own: For fresh herbs, growing your own in controlled soil can eliminate heavy metal contamination from external sources.
Key Actions Consumers Can Take to Reduce Exposure:
- Buy products from brands that publish their third-party test results.
- Pay close attention to product-specific warnings, such as California's Proposition 65.
- Don't rely solely on "organic" labels as a guarantee against heavy metals.
- Vary your spice selection to avoid relying on a single, potentially contaminated source.
- Ask manufacturers for their Certificates of Analysis (COAs) for specific product lots.
How Heavy Metals End Up in Spices
Several factors contribute to heavy metal contamination in spices:
- Soil Contamination: The primary source is often the soil where the crops are grown. Industrial pollution, past use of certain pesticides, and even natural geology can result in heavy metals building up in the soil and being absorbed by plants.
- Sourcing Location: The origin of the spice plays a significant role. Some regions of the world have higher background levels of heavy metals in the environment, making crops from those areas more likely to be contaminated.
- Processing and Packaging: While less common, contamination can also occur during processing from poorly maintained equipment or from packaging materials.
The Role of Regulatory Bodies and Standards
Regulatory bodies like the FDA in the US and the USDA's organic certification program have a role, but their current standards don't always address heavy metals comprehensively. For example, the USDA's organic standards primarily focus on prohibiting synthetic pesticides and fertilizers but do not include specific testing requirements for heavy metals. This regulatory gap is why consumer advocacy efforts and brand transparency are so important for this issue.
Conclusion
While Simply Organic has shown lower heavy metal levels in some products according to older Consumer Reports data, the presence of California Proposition 65 warnings on more recent cinnamon products proves that no brand is immune to this issue. Consumers must remain vigilant and not assume that the "organic" label guarantees freedom from heavy metal contamination. Seeking brands with proactive testing protocols and transparency, diversifying spice usage, and checking for warnings on product labels are the best ways for consumers to protect themselves and their families.
Final Thought: The presence of heavy metals in spices is an industry-wide challenge rooted in environmental contamination. While Simply Organic and other brands have acknowledged the issue and claim to test their products, inconsistencies and warnings require consumers to take an active role in researching and selecting their spices.
