The 'Dirty Dozen' Explained: Why Cherries Are on the List
For many years, the Environmental Working Group (EWG) has released its annual 'Dirty Dozen' list, a consumer guide that ranks conventionally grown fruits and vegetables with the highest pesticide residue levels. This list is compiled from data collected by the U.S. Department of Agriculture (USDA) and the Food and Drug Administration (FDA). The recurring inclusion of cherries on this list is based on testing that reveals a significant presence of chemical residues, even after standard washing and peeling processes.
The Science Behind the 'Dirty' Ranking
The EWG's ranking is not arbitrary. For cherries, specifically, tests have shown a high percentage of samples containing multiple pesticide residues. These tests are conducted on produce as it would be prepared for consumption—washed, scrubbed, or peeled. The persistent presence of these chemicals is a key factor in their 'dirty' status, indicating that simply rinsing with water may not be enough to remove all contaminants. Furthermore, some of the pesticides detected on cherries have been linked to potential health risks, making their presence a significant concern for consumers.
The Organic Alternative: Are Organic Cherries 'Clean'?
The 'Dirty Dozen' list is primarily a guide for prioritizing which produce to buy organic. Organic farming prohibits the use of synthetic pesticides and fertilizers, which significantly reduces the risk of chemical residues on the final product. While organic cherries are considered 'cleaner' due to these practices, they are not entirely free of all contaminants. Natural residues or approved organic pesticides may still be present, and handling during transport can introduce bacteria and dirt. Therefore, washing is still a critical step, even for organic produce.
Conventional vs. Organic Cherries: A Comparison
| Feature | Conventional Cherries | Organic Cherries |
|---|---|---|
| Pesticide Residue | High risk, regularly feature on the 'Dirty Dozen'. | Significantly lower risk, grown without most synthetic pesticides. |
| Farming Method | Uses a wide range of synthetic pesticides and fertilizers. | Uses natural pesticides, fertilizers, and ecological practices. |
| Washing Requirements | Thorough washing is critical to reduce residue risk. | Washing is still necessary to remove dirt, bacteria, and natural residues. |
| Cost | Generally more affordable and widely available. | Typically higher priced due to farming practices and certifications. |
| Health Benefits | Still provide numerous health benefits like vitamins and antioxidants. | Offer the same health benefits with a reduced chemical load. |
How to Properly Wash Cherries
No matter if you choose conventional or organic cherries, proper washing is non-negotiable for food safety. The USDA recommends against using soap or detergent, which can be harmful if ingested. A simple but effective method is to rinse the cherries under cold, running water in a colander, gently swishing them with your hands.
For a more thorough clean, particularly for conventionally grown cherries, a baking soda wash can be highly effective at removing pesticide residues. Research has shown that a 30-second soak in a solution of baking soda and water can be more potent than a simple water rinse. A common recipe is one teaspoon of baking soda per two cups of water.
The Best Washing Steps:
- Gather Your Cherries: Place your cherries in a colander.
- Rinse with Water: Run them under cold water, gently moving them around with your hands for about 30 seconds.
- Consider a Soak: For an extra step, particularly with conventional cherries, create a baking soda bath (1 tsp baking soda per 2 cups water) and soak for 15 minutes.
- Final Rinse: Rinse the cherries one last time under cold running water to remove any lingering residue from the soak.
- Dry Completely: Pat the cherries dry with a paper towel or use a salad spinner. Washing too far in advance can cause mold growth, so it's best to dry them thoroughly before storage.
Making an Informed Decision
Understanding why cherries are on the 'Dirty Dozen' list provides context for making informed purchasing decisions. The designation is not meant to scare consumers away from eating nutritious fruits but to empower them with knowledge. For budget-conscious shoppers, the guidance is clear: prioritizing organic versions of 'Dirty Dozen' produce helps significantly reduce pesticide exposure, while thoroughly washing all produce remains a fundamental food safety practice.
Conclusion
The classification of conventionally grown cherries as 'dirty' by the EWG is based on consistent findings of high pesticide residue levels. While they remain a healthy and delicious fruit, consumers should be aware of this potential chemical exposure. By opting for organic cherries when possible and always practicing thorough washing methods, you can minimize risk and enjoy the nutritional benefits of this popular stone fruit with greater peace of mind. Ultimately, the choice between conventional and organic cherries depends on individual priorities regarding cost, availability, and chemical exposure, but proper washing is universally important.
