Pesticides are widely used in agriculture to protect crops from pests and diseases. However, some fruits and vegetables tend to retain higher amounts of these chemicals, which may lead to concerns among consumers. Every year, the Working Group Group (EWG) releases the list of most contaminated foods, known as “Dirty Dozen.”
The most contaminated foods
The most recent study analyzed thousands of samples of fruits and vegetables tested by US government agencies. The results reveal that some varieties have a greater propensity to retain pesticides, even after washed.
Among the most contaminated foods, strawberries lead the list, followed by spinach and cabbage. These vegetables have residues of various pesticides, many of which may persist even after washing.
The full list of “Dirty Dozen” includes:
- Strawberry
- Spinach
- Kale, cauliflower and pound
- Grapes
- Peach
- Pear
- Nectarines
- Apple
- Peppers and peppers
- Cherry
- Blueberry
- Green bean
Should I worry about the pesticides?
Most food security entities, including the US Environmental Protection Agency, say that pesticide residues found in food are within the limits considered safe for human consumption. However, some studies point to possible long -term effects of exposure to these substances.
Frequent pesticide intake may be associated with health problems such as hormonal dysfunctions, neurological disorders and some cancers. Although the specific impact depends on the amount and type of pesticide, choosing products with less waste can be a safer choice.
How to reduce exposure to pesticides?
Correct food washing, according to, is one of the best ways to minimize pesticide intake. Wash the fruits and vegetables in running water and rubbing them with a brush can help remove part of the waste. In some cases, peeling foods can also be effective.
Another option is to opt for biological products, which are cultivated without the use of synthetic pesticides. Although they are generally more expensive, they can offer an alternative to those who want to avoid these substances as much as possible.

The safest foods
Not all fruits and vegetables have high levels of pesticides. EWG also releases a list of products with less propensity to contain waste, known as “Clean Fifteen”.
Among the safest are:
- Avocados
- Sweet corn
- Pineapple
- Onions
- Papaya
- Sweet (frozen) peas)
- Sparks
- Melon
- Kiwi
- Cabbage
- Watermelon
- Mushrooms
- Sleeves
- Sweet potato
- Carrots
Conclusion: Is it worth changing habits?
For most people, the consumption of fruits and vegetables is still essential for a balanced and healthy diet. However, knowing foods with higher pesticide load can help make more informed decisions about food.
Choosing products with fewer pesticides, washing food well, and when possible, choosing biological versions are some strategies to reduce the risk of exposure to these substances. After all, health is the most precious good we have.
