Understanding the Dirty Dozen and Pears
The Environmental Working Group (EWG) publishes its "Dirty Dozen" list annually to highlight the fruits and vegetables with the highest pesticide residues based on USDA test data. In recent years, pears have been a consistent addition to this list, a trend driven by agricultural testing that shows a significant increase in pesticide contamination over time. The EWG's analysis of USDA tests from 2021 and 2022 revealed a concerning rise in the number and concentration of pesticides found on conventional pears. The findings indicated that 95% of pear samples had at least one pesticide detected, and more than 60% had five or more. This contrasts sharply with earlier tests and highlights why pears are now a key concern for consumers seeking to minimize pesticide exposure.
Why are Pears on the Dirty Dozen? The Data
The reason for pears' inclusion on the Dirty Dozen list is twofold: the sheer number of different pesticides found on a single fruit and the increased concentration of these chemicals. Fungicides and insecticides are among the most commonly detected pesticides on pears, some of which are applied during the growing season and others post-harvest to prevent spoilage. Certain fungicides, like pyrimethanil and fludioxonil, were frequently detected in high concentrations, raising concerns among some scientists about potential health impacts. The EWG reports these findings not to discourage fruit consumption, but to provide information that helps consumers decide when it is most beneficial to choose organic.
How to Minimize Pesticide Exposure from Pears
For those concerned about pesticide residues, there are several actions you can take without giving up this healthy and delicious fruit:
- Choose organic: The most direct method is to purchase certified organic pears. Organic farming practices prohibit the use of the synthetic pesticides found on the Dirty Dozen list.
- Wash thoroughly: For conventional pears, washing them under running water for 15-20 seconds can help reduce surface pesticides. Some studies suggest that a 30-second soak in a baking soda solution (2 teaspoons per quart of water) can be even more effective at removing certain residues.
- Peel the skin: The skin of a pear contains much of the fiber and antioxidants, but also the highest concentration of pesticide residue. Peeling the skin will significantly reduce pesticide intake, though it also removes some nutrients.
- Cook the pear: Cooking can reduce the concentration of some pesticides. This is an excellent option for baking or making sauces, as some individuals prefer to cook unpeeled pears for added nutrients and texture.
Organic vs. Conventional Pears: A Comparison
To make an informed choice, consider the differences between organically and conventionally grown pears. Research has explored the quality and nutritional content of pears produced under these different methods.
| Feature | Conventional Pears | Organic Pears |
|---|---|---|
| Pesticide Residue | High levels of multiple synthetic pesticides are frequently detected. | No synthetic pesticides are used in their production. |
| Cost | Generally more affordable and widely available in stores. | Typically more expensive due to higher production costs. |
| Nutritional Content | Studies have shown comparable levels of vitamins and minerals. | Some studies suggest organic pears contain higher levels of certain nutrients and antioxidants. |
| Microbial Profile | Different microbial community structure, potentially due to pesticide use. | Contains different and potentially higher levels of beneficial microorganisms, which can affect shelf life. |
| Pest Control | Relies on synthetic pesticides to manage pests and diseases. | Uses natural methods like mating disruption and beneficial insects. |
Making the Best Choice for Your Health
When considering whether to buy organic or conventional pears, the decision comes down to balancing cost, availability, and personal priorities regarding pesticide exposure. While pesticide levels on conventional pears may not pose an immediate or acute health risk for most consumers, the long-term effects of ingesting multiple pesticides are still under study. The Environmental Working Group's list serves as a valuable guide for prioritizing your organic purchases, helping you decide which items warrant the extra investment. Remember, the most important thing is to eat plenty of fruits and vegetables, as their health benefits far outweigh the risks associated with pesticide exposure from conventional produce. For peace of mind with pears, choosing organic is the simplest way to avoid pesticide residues. If you opt for conventional, washing thoroughly and considering peeling can significantly reduce your exposure.

Conclusion
Pears have landed on the Environmental Working Group's Dirty Dozen list due to a documented rise in pesticide residues on conventionally grown fruit. While conventional pears are not inherently unsafe, and their consumption is not advised against by organizations like the EWG, consumers concerned about pesticide load should consider buying organic. Thorough washing is also a key strategy for reducing exposure for those who prefer or need to buy conventional produce. Ultimately, the choice depends on individual priorities, but armed with the right information, consumers can confidently make decisions that align with their health and environmental goals while continuing to enjoy the many nutritional benefits pears offer.
