Is Celery Dirty Dozen? Understanding Pesticide Concerns and Safer Choices

Posted Last Updated

Yes, celery is frequently included in the Environmental Working Group’s (EWG) annual “Dirty Dozen” list, which identifies conventionally grown produce with the highest levels of pesticide residues. For example, in 2026, celery was ranked among the produce with significant pesticide concerns, appearing at number 17 on the full list of 47 tested items (where lower numbers indicate higher pesticide contamination). This ranking indicates that conventional celery can carry a considerable pesticide load, even after being washed. The EWG bases its lists on USDA pesticide residue data, with an updated methodology that considers not just the quantity but also the toxicity of detected pesticides.

Understanding the Dirty Dozen helps you make informed choices about your food. Knowing which fruits and vegetables tend to have higher pesticide levels allows you to prioritize organic options or take extra precautions with conventional produce.

Yes, Celery Is Frequently on the Dirty Dozen List

The Environmental Working Group (EWG) consistently lists celery as a concern for pesticide residues. While it may not always be in the top 12, it often ranks high on their extended list of produce with significant pesticide contamination. In 2026, celery was ranked number 17 out of 47 fruits and vegetables.

This placement means conventional celery is among produce items with more pesticide residue. EWG’s methodology considers factors like the abundance, diversity, intensity, and toxicity of detected pesticides.

The USDA Pesticide Data Program tests produce samples, even after washing and peeling. These tests often find multiple pesticide residues on celery.

Understanding the Dirty Dozen: What It Means for Your Produce

The Dirty Dozen is an annual list compiled by the Environmental Working Group (EWG). It highlights 12 conventionally grown fruits and vegetables most contaminated with pesticide residues.

EWG uses USDA data to create this list. Their updated methodology since 2025 incorporates pesticide toxicity.

This means the list reflects real-world health risk more accurately. The EWG aims to empower consumers with information.

It helps you decide which produce to buy organic. However, EWG emphasizes eating produce, organic or conventional, is important for health.

Why Celery Tends to Have High Pesticide Residues

Celery’s physical structure makes it prone to absorbing pesticides. Its stalks are porous and lack a protective skin.

This allows pesticides to penetrate the plant tissues easily. Farmers often use various pesticides on celery.

These include insecticides and fungicides to manage pests and diseases. Pesticides like imidacloprid and acetamiprid are frequently used.

Government lab tests have detected an average of approximately five pesticides per celery stalk. Some celery samples have contained as many as 13 different chemicals.

About 95 percent of celery samples tested positive for pesticides. About 85 percent contained several different chemicals.

The leaves and roots readily absorb these chemicals. This makes washing conventional celery less effective at removing all residues.

Minimizing Pesticide Exposure: Practical Steps for Celery and Other Produce

Reducing pesticide exposure is achievable with mindful shopping and preparation. Prioritizing organic produce is the most effective strategy.

Studies show eating organic food significantly lowers pesticide levels in the body. Organic farming relies on natural processes, not synthetic chemicals.

Thorough Washing Techniques

Washing produce correctly removes dirt, insects, and some pesticide residues. Rinse celery stalks under cold running water.

You can also soak celery in a cold water bath for a few minutes. Scrub firm produce, like celery, gently with a vegetable brush.

The USDA advises against using soap or commercial produce washes. These are no more effective than water alone.

For extra caution, soak celery in water with a splash of white vinegar. A 10% salt water solution or baking soda solution can also be effective.

Consider Peeling Some Produce

Peeling certain fruits and vegetables can further reduce pesticide exposure. This method is effective for produce with thicker skins. Peeling celery is not practical due to its fibrous nature.

Growing Your Own

Cultivating your own celery offers full control over growing practices. This eliminates concerns about commercial pesticide use. Home gardening provides fresh, chemical-free produce.

Exploring Alternatives to Conventional Celery

Opting for organic celery is the simplest way to reduce pesticide exposure. Certified organic celery is grown without synthetic pesticides.

If organic celery is not available or too expensive, consider other low-pesticide vegetables. The EWG’s “Clean Fifteen” lists produce with the lowest pesticide residues.

These include avocados, sweet corn, pineapples, onions, and cabbage. Carrots, mushrooms, and kiwi are also on the Clean Fifteen.

Prioritizing these options helps reduce overall pesticide intake. Remember, eating any fruits and vegetables is beneficial for health.

Dietary benefits of produce outweigh potential risks from pesticide residues. Focus on incorporating a variety of clean options into your diet.

Frequently Asked Questions About Celery and Pesticides

Is organic celery worth the extra cost?

Yes, organic celery is generally worth the extra cost to significantly reduce pesticide exposure. Conventional celery often carries multiple pesticide residues due to its growth structure. Studies indicate that choosing organic produce can lead to lower pesticide levels in the body.

Does washing celery remove all pesticides?

Washing celery thoroughly can remove some surface pesticide residues, but it will not eliminate all of them. Celery’s porous stalks absorb pesticides into its tissues. The USDA and FDA advise washing with water, but this does not guarantee complete removal.

What is the Clean Fifteen?

The Clean Fifteen is a list published annually by the Environmental Working Group (EWG). It identifies 15 conventionally grown fruits and vegetables with the lowest amounts of pesticide residues. These items are generally considered safer to buy in their conventional form.

Should I stop eating celery if it’s on the Dirty Dozen?

No, you should not stop eating celery. The health benefits of consuming fruits and vegetables, including celery, outweigh the potential risks from pesticide exposure. If concerned, prioritize organic celery or wash conventional celery thoroughly.

Making Informed Choices for Healthier Eating

Understanding the Dirty Dozen list helps consumers make educated decisions in the grocery aisle. Celery’s position on this list highlights its vulnerability to pesticide residues. Prioritizing organic versions of items like celery can significantly reduce dietary pesticide exposure.

However, consistent consumption of all fruits and vegetables remains crucial for overall health. If organic options are not accessible, thorough washing and varied produce choices are beneficial strategies. Balance and awareness empower healthier eating habits for everyone.
