One way to limit your exposure to pesticides is by choosing organic produce. However, buying organic all the time can be pricey and might not always fit your budget. The good news? Some fruits and vegetables naturally have lower levels of pesticide contamination, making them safe to buy conventionally. These items are often protected by their thick skins or natural growing patterns, which reduce the need for chemical treatments.
If you’re looking to save money while making smarter choices, Here’s the 2024 Clean Fifteen list to help you shop smarter! This guide, updated yearly by the Environmental Working Group (EWG), highlights produce with the lowest pesticide residues. These fruits and veggies are your best bets for buying non-organic while still keeping your meals healthy and safe.
Avocados
Avocados have one of the lowest pesticide contamination rates, with less than 2% of tested samples showing any residues. This protein-packed food has a thick, rough skin that acts as a natural barrier, keeping the edible part well-protected from chemicals. This protective layer significantly reduces the need for pesticides during farming. As a result, they’re consistently ranked as one of the cleanest produce items available.
Sweet Corn
Sweet corn’s protective husk shields the kernels from both pests and chemical exposure, making it one of the least contaminated crops. Less than 2% of tested samples showed any pesticide residues, solidifying its spot on the Clean Fifteen. Additionally, sweet corn often doesn’t require multiple chemical treatments due to its natural growth patterns. Its minimal pesticide presence makes it a reliable option for conventional purchases.
Pineapple
Pineapples owe their low pesticide contamination to their tough, spiky exterior, which acts as a natural defense against pests. Almost no residues were detected in tested samples, as their thick skin reduces the need for chemical treatments. Since the inedible skin isn’t consumed, the risk of pesticide exposure is further minimized. Their structural protection makes them a great non-organic option.
Onions
Onions have a natural chemical composition that repels pests, requiring very little pesticide use during cultivation. Their papery outer skin provides an additional layer of defense, keeping residues from reaching the edible bulb. Tests consistently show that onions have some of the lowest pesticide levels among vegetables. Learn how to store onions properly to keep them fresh and flavorful for longer, whether you use them raw or cooked in your favorite dishes.
Papaya
Papayas feature a thick, sturdy skin that helps protect the fruit from pests and chemical residues. Testing revealed minimal pesticide presence in this low-sugar fruit, with most samples showing no detectable contamination. Additionally, papaya trees are naturally resilient, reducing the need for frequent chemical applications. Their ability to grow with less pesticide use makes them a responsible non-organic choice.
Sweet Peas (Frozen)
Sweet peas, often grown inside protective pods, are naturally shielded from pests and external chemical exposure. Pesticide residue testing revealed low levels, with no sample containing more than three pesticides. The freezing process further preserves their cleanliness, making them a practical and safe option. Their resilience during farming minimizes the reliance on chemical treatments.
Asparagus
Asparagus naturally resists pests due to its unique growing process, reducing the need for pesticides. Test results confirm that it ranks low in chemical residues, making it one of the cleanest vegetables. Its tightly packed stalks add an extra layer of defense against potential contamination. This natural hardiness makes asparagus a great candidate for non-organic purchasing.
Honeydew Melon
Honeydew melons are well-protected by their thick rinds, which prevent pesticides from reaching the juicy fruit inside. Samples tested showed little to no chemical residues, securing their place on the Clean Fifteen. Their low pest vulnerability reduces the need for heavy chemical applications during farming. This natural barrier ensures honeydew remains a safe choice for conventional shoppers.
Kiwi
Kiwi fruit features a fuzzy outer skin that acts as a physical shield, keeping pesticide contamination to a minimum. Testing found extremely low levels of residues, making it one of the safest fruits to consume non-organically. The fruit’s compact size and robust growing process further limit the need for chemical treatments.
Cabbage
Cabbage’s densely packed leaves provide natural protection from pests, reducing the need for pesticide sprays. Its tightly layered structure helps block chemical exposure to the inner leaves. Testing revealed minimal residues, showing that it consistently ranks among the cleanest vegetables. This natural defense mechanism makes cabbage a dependable and low-risk conventional option.
Watermelon
Watermelons benefit from their thick, inedible rinds, which form a strong barrier against pesticide absorption. Test results show very low contamination levels in this water-rich food, ensuring the fruit inside remains clean and safe. Their large size and natural growing conditions also contribute to their low need for chemical treatments. Watermelon’s protective structure helps maintain its place on the Clean Fifteen.
Mushrooms
Mushrooms are cultivated in controlled environments, which greatly reduces their exposure to pests and pesticides. Testing consistently shows negligible pesticide residues, as these fungi rarely require chemical sprays to thrive. Their ability to grow in nutrient-rich soil with minimal intervention contributes to their consistently clean profile. Learn how to clean mushrooms properly to ensure they’re ready for cooking while preserving their delicate texture and flavor.
Mangoes
Mangoes are protected by their thick, smooth skin, which limits pesticide penetration to the edible fruit. Testing showed very low pesticide levels, even in conventional samples. Their resilience during growth further reduces the need for chemical applications. This protective quality ensures mangoes remain a low-risk fruit for consumers.
Sweet Potatoes
Sweet potatoes grow underground, naturally shielding them from pests and reducing the need for pesticides. Tests reveal consistently low residue levels, showing that they’re one of the cleanest root vegetables available. Their tough, fibrous skin provides an extra layer of protection against chemical exposure. These factors make sweet potatoes a safe and practical choice for conventional purchases.
Carrots
Carrots’ underground growth helps keep them naturally protected from most pests, limiting the necessity for chemical treatments. Testing confirmed low pesticide residues, making them a safe addition to the Clean Fifteen. Their compact shape and smooth skin also reduce the likelihood of chemical absorption. This combination of natural defenses ensures carrots remain one of the cleanest non-organic vegetables.
