The Agricultural Divide: Pesticides and Farming Practices
The fundamental difference between conventional and organic almonds begins with how they are grown. Conventional farming relies on synthetic chemicals to maximize crop yield and prevent pests, while organic farming opts for natural methods. A deeper look at the chemicals and practices used provides a clearer picture of the distinction.
The Role of Pesticides in Conventional Almond Farming
Conventional almond orchards in major growing regions, like California, utilize a variety of synthetic pesticides, herbicides, and fungicides to control pests and disease. Concerns about these chemicals include:
- Residue levels: While the U.S. Food and Drug Administration (FDA) sets tolerance limits for pesticide residues, some evidence suggests that certain chemicals may persist on the final product. The Pesticide Action Network North America has reported significant pesticide use on conventionally grown almonds, raising long-term health concerns about cumulative exposure.
- Environmental contamination: The use of these chemicals, including glyphosate, has been linked to potential harm to beneficial insects like bees, which are crucial for almond pollination. Runoff from farms can also contaminate groundwater supplies.
- Absorption: Nuts have a naturally high oil content, which can cause them to absorb chemical treatments more readily than other foods, meaning residues can be absorbed beyond the surface.
Organic Almond Farming: A Chemical-Free Approach
Organic almonds are cultivated without synthetic pesticides, herbicides, or fertilizers. Organic farmers employ natural pest control methods and focus on improving soil health through practices like crop rotation and using natural fertilizers. This approach benefits both the environment and consumers by:
- Reducing chemical exposure: Choosing organic helps minimize exposure to synthetic chemical residues often found on conventional produce.
- Protecting ecosystems: Organic farming practices promote biodiversity, conserve water, and reduce chemical runoff, which protects local water sources and vital pollinators.
The Pasteurization Process: PPO vs. Steam
In the wake of salmonella outbreaks, the U.S. government mandated the pasteurization of all raw almonds sold domestically. This means even “raw” almonds are not truly unpasteurized. The method of pasteurization, however, varies significantly between conventional and organic varieties.
Propylene Oxide (PPO) in Conventional Almonds
Many conventional almonds are pasteurized using a chemical fumigant called propylene oxide (PPO). The FDA-approved process effectively reduces bacteria like salmonella. While PPO dissipates to safe levels below the FDA’s tolerance limit by the time almonds reach consumers, some people prefer to avoid ingesting any level of a chemical classified as a potential carcinogen by the Environmental Protection Agency (EPA).
The Steam Pasteurization of Organic Almonds
Organic certification prohibits the use of PPO. Instead, organic almonds are pasteurized using a natural process involving moist heat, typically steam. This method achieves the required sanitation without chemical intervention, preserving the purity of the almonds for those concerned about chemical exposure.
Potential Health Considerations: Residues and Nutrition
When considering potential health impacts, it’s important to look at both the chemicals and the nutritional content. While conventional almonds carry a higher risk of chemical residues, their core nutritional value remains consistent.
- Chemical residues: As discussed, conventional almonds may contain trace pesticide and PPO residues. Though legal, some research suggests a link between long-term, low-level pesticide exposure and health issues. Choosing organic eliminates these specific chemical concerns.
- Nutritional content: The core nutritional benefits of almonds, including healthy fats, fiber, protein, and antioxidants, are present in both organic and conventional varieties. A 2025 study suggested that conventionally cultivated almonds might have higher mineral content but lower fatty acid value compared to organic, though overall differences were minor. For most consumers, the health benefits of eating almonds outweigh the minimal differences based on farming method.
Environmental Impact: Beyond Your Body
For many, the decision between organic and conventional is not solely about personal health but also about broader environmental and ethical concerns. The intensive agriculture model of conventional almond farming has come under scrutiny.
- Water usage: Almonds are a water-intensive crop, and a significant portion of the world's supply is grown in California, a region often plagued by drought.
- Pollinator health: The heavy use of synthetic pesticides in conventional fields has been linked to harm and population decline in vital pollinators like bees, which are essential for almond pollination.
- Sustainable practices: Organic farming supports better soil health, biodiversity, and reduced chemical runoff, leading to a healthier ecosystem and more sustainable agricultural practices.
Conventional vs. Organic Almonds: A Comparison
| Feature | Conventional Almonds | Organic Almonds |
|---|---|---|
| Farming | Uses synthetic pesticides, herbicides, and fertilizers. | Uses natural methods for pest control and soil enrichment. |
| Pasteurization | Often treated with the chemical fumigant Propylene Oxide (PPO). | Uses a natural steam pasteurization process. |
| Pesticide Residue | Contains trace residues of synthetic pesticides, within FDA limits. | Grown without synthetic pesticides, resulting in no chemical residue from these agents. |
| Cost | Generally more affordable due to economies of scale and higher yields. | More expensive due to labor-intensive practices and lower yields. |
| Environmental Impact | Associated with chemical runoff and potential harm to pollinators. | Supports healthier ecosystems, soil, and biodiversity. |
| Nutritional Profile | Offers significant nutritional benefits. A recent study found potentially higher mineral content. | Offers significant nutritional benefits. A recent study found potentially higher fatty acid content. |
Which Almonds Should You Choose?
The choice between conventional and organic almonds ultimately depends on your priorities. For those whose primary concern is minimizing exposure to synthetic chemicals and supporting sustainable agriculture, organic almonds are the clear choice. The higher cost reflects these more environmentally-friendly practices.
For those on a budget, conventional almonds remain a nutritionally sound and safe option. Regulatory bodies ensure that pesticide and PPO residue levels are within safe limits for consumption. The core nutritional benefits are present in both versions, making conventional almonds a healthy choice despite the different production methods.

Conclusion: Making an Informed Choice
So, are almonds bad if not organic? The simple answer is no; conventional almonds are not inherently bad or unsafe. Both organic and conventional almonds offer excellent nutritional value and are safe for consumption under federal regulations. The core difference lies in the farming and pasteurization methods used and the associated environmental impact. Organic almonds minimize chemical exposure and support more sustainable practices, while conventional almonds provide an affordable, nutrient-rich option that meets all safety standards. By understanding these differences, consumers can make an informed decision that aligns with their personal values and health priorities, ensuring they can enjoy the benefits of almonds regardless of their preference.
