Carrots and the Clean Fifteen: A Closer Look
When it comes to navigating the grocery store aisles with health in mind, many consumers reference the Environmental Working Group's (EWG) 'Dirty Dozen' and 'Clean Fifteen' lists. These guides are meant to help shoppers decide which fruits and vegetables are worth buying organic to minimize pesticide exposure. The good news for carrot lovers is that for 2025, conventionally grown carrots are firmly on the 'Clean Fifteen' list, not the 'Dirty Dozen'. This means that while they may contain some pesticide residue, the levels are among the lowest detected in conventionally grown produce. This designation makes them a relatively safe and budget-friendly choice for health-conscious shoppers.
The Meaning of the EWG's Produce Lists
The EWG's lists are based on data from the U.S. Department of Agriculture (USDA) and the Food and Drug Administration (FDA) that tests thousands of produce samples each year. The EWG ranks produce based on several factors, including the percentage of samples with detectable pesticides and the total number and amount of pesticides found.
The Dirty Dozen
This list highlights the fruits and vegetables with the highest amount of pesticide residue. The 2025 Dirty Dozen includes items like strawberries, spinach, and kale, among others. The EWG suggests buying organic versions of these foods to reduce pesticide intake.
The Clean Fifteen
Conversely, the Clean Fifteen includes produce with the lowest pesticide residues. These items are generally considered safer to purchase conventionally. Carrots make this list due to several factors, including being a root vegetable and the effectiveness of washing and peeling. Many items on this list, like onions and avocados, have a protective outer layer that is removed before consumption, though this is not always the case, as seen with carrots.
Why Conventionally Grown Carrots Rank Low in Pesticides
Several reasons contribute to carrots' favorable ranking on the Clean Fifteen:
- Growth Location: As a root vegetable, carrots grow underground. While they are still exposed to soil-borne pests and fungicides, this sub-surface growth can offer some protection compared to fruits and leafy greens that are more exposed to aerial spraying.
- Washing and Peeling: Routine consumer behavior, such as washing and peeling carrots, significantly reduces the amount of pesticide residue on the vegetable. This post-harvest processing plays a major role in their safety profile.
- Lower Residue Levels: USDA testing data consistently shows that conventional carrots have lower and fewer types of pesticide residues compared to produce on the Dirty Dozen. In fact, nearly 60% of produce on the Clean Fifteen had no detectable pesticide residue at all.
Washing and Prepping Carrots
Regardless of whether you buy organic or conventional, properly preparing your produce is crucial for reducing contaminants. For carrots, this means a thorough wash.
Steps for washing carrots:
- Hold carrots under cold running water.
- Use a clean vegetable brush to scrub the entire surface, especially if you plan to eat them unpeeled.
- For extra assurance, you can peel the carrots, which removes the outermost layer where any lingering residues may be concentrated.
Comparing the Lists: Dirty Dozen vs. Clean Fifteen
| Feature | Dirty Dozen | Clean Fifteen |
|---|---|---|
| Pesticide Residue Level | Highest | Lowest |
| Recommendation | Buy organic versions to minimize exposure. | Generally safe to buy conventional versions. |
| Example Items (2025) | Strawberries, Spinach, Kale, Grapes, Apples, Potatoes | Carrots, Avocados, Sweet Corn, Onions, Pineapple |
| Consumer Impact | May be avoided by budget-conscious shoppers. | Provides safe conventional options for budget-friendly shopping. |
The Broader Context: A Balanced Perspective
While the Dirty Dozen and Clean Fifteen provide a helpful framework, they are not without controversy. Critics argue that focusing too much on low-level pesticide exposure can cause "chemophobia" and discourage people from eating enough fruits and vegetables, especially those on a budget. Health experts consistently agree that the health benefits of consuming a diet rich in fruits and vegetables far outweigh the potential risks from the trace levels of pesticides found on conventional produce. The core message is to eat more produce, whether organic or conventional. For those who can afford it and are concerned about pesticide levels, prioritizing organic versions of items on the Dirty Dozen is a practical strategy. For others, thoroughly washing conventional produce is an effective and sufficient approach.
Practical Shopping Strategies
- Prioritize Organics: If your budget allows, focus on buying organic versions of the items that appear on the Dirty Dozen list each year.
- Choose Conventionally: For produce on the Clean Fifteen, such as carrots, it is generally safe to choose the less expensive conventional option.
- Wash Everything: Regardless of the list or label, always wash your fruits and vegetables thoroughly before consuming them to remove dirt, bacteria, and any surface residues.

Conclusion
To answer the primary question, no, carrots are not on the Dirty Dozen. They are featured on the EWG's Clean Fifteen, indicating they have low pesticide residue levels when grown conventionally. This provides a welcome reassurance for consumers who enjoy this nutritious root vegetable. While the debate surrounding pesticide exposure continues, a balanced approach that focuses on eating plenty of produce and washing it well is the best strategy for promoting overall health.
