Eating fresh fruits and vegetables is essential for a healthy lifestyle, but not all produce is as safe as it appears. Many conventional fruits and vegetables are heavily treated with pesticides to protect them from pests and diseases. While washing produce can reduce some of the pesticide residue, it often doesn’t eliminate it entirely. The Environmental Working Group (EWG) releases a list every year detailing the most pesticide-laden produce, allowing consumers to make more informed decisions. Let’s take a look at 12 fruits and vegetables that often contain dangerous levels of pesticides.
1. Strawberries
Strawberries are often at the top of the list when it comes to pesticide contamination. The EWG has repeatedly found that conventional strawberries are sprayed with a wide variety of chemicals, some of which are harmful to human health. Because strawberries have soft skin, they absorb pesticides easily, making it difficult to remove residues through washing alone. According to the EWG, more than 90% of conventional strawberries have detectable pesticide residues, including those linked to cancer and hormone disruption.
For those who want to avoid pesticide exposure, organic strawberries are the safest option. The Environmental Protection Agency (EPA) has set maximum residue limits for some pesticides used on strawberries, but these limits are often higher than what some experts deem acceptable. To reduce your risk, buy organic strawberries whenever possible, or consider growing your own if you have the space. By making the switch to organic, you’ll be reducing your exposure to harmful pesticides while enjoying this popular fruit.
2. Spinach
Spinach is another popular vegetable that frequently makes the list for pesticide contamination. According to the Iowa Farm Bureau, conventional spinach is often treated with multiple types of pesticides, including fungicides and insecticides. Since spinach has delicate, porous leaves, it’s particularly susceptible to absorbing these chemicals. Even washing it thoroughly may not completely remove pesticide residues, leaving consumers vulnerable to potential health risks.
Organic spinach is a much safer choice for those looking to minimize their pesticide exposure. The use of synthetic pesticides is strictly regulated in organic farming, meaning less harmful chemicals end up on your plate. If organic spinach is not available, you can try soaking your spinach in a vinegar-water solution to help reduce pesticide residue. However, to be truly safe, organic spinach remains the best option for health-conscious consumers.
3. Kale
Kale, like spinach, has become a staple in many people’s diets due to its health benefits. However, conventional kale is often heavily sprayed with pesticides, making it one of the worst offenders when it comes to chemical residues. The Guardian highlights that kale is regularly treated with insecticides and herbicides that can have detrimental effects on human health. Washing kale might remove some surface pesticides, but not all of them, especially when they are absorbed into the leaves.
Opting for organic kale is the most effective way to avoid pesticide exposure. Organic farming prohibits the use of many harmful pesticides, offering a healthier alternative to conventionally grown kale. For those who cannot find organic kale, soaking it in a baking soda solution may help remove some pesticide residues. Ultimately, choosing organic kale is your best bet for a pesticide-free, nutritious meal.
4. Apples
Apples are among the most popular fruits in the United States, but they often contain high levels of pesticide residues. According to a report from CNN, conventional apples are frequently treated with several types of pesticides, including some linked to serious health concerns like developmental issues in children. These pesticides are used to protect apples from pests and diseases but can remain on the fruit even after washing. The smooth skin of apples makes it difficult to remove all of the chemical residues, especially with conventional varieties.
Buying organic apples is the most effective way to reduce your pesticide exposure. Organic apple farming uses natural alternatives to synthetic chemicals, providing a cleaner, safer fruit for consumers. If organic apples are not available, washing them with water and a vegetable wash may help reduce pesticide residues, though it’s unlikely to remove all traces. In any case, choosing organic apples when possible is highly recommended for those concerned about pesticide contamination.
5. Grapes
Grapes are another fruit that tends to contain a significant amount of pesticide residue. Since grapes are often grown in regions where pests are a major concern, conventional grapes are sprayed with multiple pesticides to protect them during the growing season. Grapes frequently contain pesticides linked to issues such as cancer and reproductive harm. These pesticides can be difficult to remove through washing, as they tend to penetrate the thin skin of the grape.
Opting for organic grapes is the best way to ensure that you’re not ingesting harmful chemicals. Organic grapes are grown without synthetic pesticides, offering a safer alternative for health-conscious consumers. If organic grapes aren’t available, soaking them in a solution of water and vinegar may help reduce pesticide residues. However, washing may not be enough to completely remove harmful chemicals, so organic grapes are always the safest choice.
6. Peaches
Peaches are known for their sweet, juicy flavor, but they are also one of the most pesticide-contaminated fruits. Peaches have delicate, fuzz-covered skin that easily absorbs pesticides, making them a prime candidate for chemical residue. Conventional peaches are often treated with several types of pesticides to protect them from insects and fungal infections. Even washing them may not remove all of the harmful residues, which is why choosing organic peaches is highly recommended.
Organic peaches are grown without the use of synthetic chemicals, reducing the risk of pesticide exposure. Since peaches are typically eaten with the skin on, choosing organic varieties ensures you’re not ingesting harmful pesticides. If you cannot find organic peaches, washing them thoroughly may reduce pesticide levels, but it’s unlikely to remove all residues. To minimize health risks, always choose organic peaches when possible.
7. Pears
Like peaches, pears are often treated with a variety of pesticides to protect them during growth. Conventional pears are regularly sprayed with chemicals that can leave harmful residues on the fruit’s skin. Since pears are usually eaten with their skin, the pesticides can be ingested even after washing. The soft texture of pears makes them especially prone to absorbing pesticides, which is why organic pears are a better choice for consumers.
Organic pears are grown without synthetic pesticides, providing a healthier alternative to conventional pears. If you’re concerned about pesticide exposure, organic pears are the safest option for you. If organic pears are not available, washing them thoroughly or peeling the skin may help reduce pesticide levels. However, for the best protection against pesticides, it’s always a good idea to choose organic pears when possible.
8. Nectarines
Nectarines are another stone fruit that can harbor significant pesticide residues. These fruits, which are closely related to peaches, often have thin, smooth skin that can absorb chemicals during the growing process. Nectarines are commonly treated with insecticides and fungicides, making them one of the most pesticide-contaminated fruits on the market. Since nectarines are often eaten with the skin on, even thorough washing may not eliminate all pesticide residues.
To avoid pesticide exposure, choose organic nectarines when possible. Organic nectarines are grown without synthetic chemicals, offering a safer alternative for those concerned about pesticide contamination. If organic nectarines aren’t available, washing them thoroughly with water and vinegar can help reduce pesticide residues.

To be fully safe, organic bell peppers are always the best choice.
10. Celery
Celery is another vegetable commonly contaminated with pesticides, often ranking high on the EWG’s Dirty Dozen list. Conventional celery is treated with a variety of chemicals to prevent pest damage, but these chemicals can remain on the vegetable’s surface even after washing. Since celery is typically eaten raw, pesticide residues may be ingested directly unless the celery is washed thoroughly or peeled. The porous nature of celery stalks makes it especially susceptible to absorbing pesticides, making organic celery the best choice.
If you can’t find organic celery, it’s important to wash it thoroughly before consuming. Soaking celery in a vinegar-water solution can help reduce pesticide residues, but it may not eliminate all of them. Organic celery remains the safest option for those looking to reduce their pesticide exposure. Whenever possible, opt for organic celery to ensure you’re eating a cleaner, healthier vegetable.
11. Potatoes
Potatoes are frequently treated with pesticides, particularly fungicides and insecticides, during the growing process. Potatoes can have high pesticide residues, which are often absorbed into the potato itself. Since potatoes are typically eaten with the skin on, these chemicals can be ingested unless the potatoes are thoroughly washed or peeled. The thick skins of potatoes make it especially difficult to wash off pesticide residues, so buying organic potatoes is always the best option.
If you can’t find organic potatoes, peeling them before consumption can help reduce pesticide exposure. However, organic potatoes remain the safest choice for reducing harmful chemical residues. Washing potatoes with water and a vegetable wash can help remove some of the pesticides, but it may not eliminate them entirely. To avoid exposure to harmful chemicals, always choose organic potatoes when possible.
12. Tomatoes
Tomatoes are another widely consumed fruit that often contains pesticide residues. Conventional tomatoes are frequently sprayed with insecticides and fungicides to protect them from pests and fungal infections. Tomatoes can retain these chemicals even after washing, making them one of the top pesticide-contaminated produce items. If you’re concerned about pesticide exposure, organic tomatoes are the safest option.
Organic tomatoes are grown without the use of synthetic pesticides, providing a healthier alternative to conventional tomatoes.
