Every year, the Environmental Working Group (EWG) releases their highly anticipated Dirty Dozen and Clean Fifteen lists, and 2025 brings some important updates that could affect your grocery shopping decisions. These lists rank produce by pesticide contamination levels, helping consumers make informed choices about when to spend extra on organic options.

With organic produce often costing 20-50% more than conventional options, knowing which items are worth the extra investment can save you hundreds of dollars annually while still protecting your family's health.

The Dirty Dozen 2025

These 12 items tested positive for the highest levels of pesticide residues. Buy these organic whenever possible:

  3. 3
    Kale, Collard & Mustard Greens - 90% of samples tested contained pesticide residues
  4. 4
    Peaches - 99% tested positive for at least one pesticide residue
  5. 5
    Pears - New to the list this year with increased pesticide detection
  6. 6
    Nectarines - Nearly 95% of samples contained pesticide residues
  7. 7

Key Takeaways for Smart Shopping

  • Prioritize your budget: If you can't afford all organic, focus on the Dirty Dozen items first
  • Wash thoroughly: Even organic produce should be washed to remove dirt and bacteria
  • Consider frozen: Frozen organic options are often more affordable and equally nutritious
  • Don't skip produce: The health benefits of eating fruits and vegetables outweigh pesticide risks
  • Shop seasonally: Local, in-season produce often has lower pesticide levels

Understanding the Science Behind the Lists

The EWG analyzes over 46,000 samples of produce tested by the USDA and FDA. Their methodology includes:

Testing Protocols

All produce is tested after washing and peeling, just as consumers would prepare it at home, making results more realistic.

Multiple Metrics

Rankings consider total pesticide concentration, number of different pesticides found, and maximum levels detected.

Why Pesticide Exposure Matters

While conventional produce is generally safe to eat, reducing pesticide exposure offers several potential health benefits:

Neurological Development

Studies link high pesticide exposure during pregnancy and childhood to developmental delays and reduced IQ scores.

Hormonal Balance

Many pesticides act as endocrine disruptors, potentially affecting reproductive health and hormone regulation.

Long-term Health

Research suggests chronic pesticide exposure may increase risks for certain cancers, Parkinson's disease, and other conditions.

Budget-Friendly Strategies

1

Mix Organic and Conventional

Buy organic versions of Dirty Dozen items and conventional Clean Fifteen items to reduce costs by up to 40% while minimizing exposure.

2

Shop Farmers Markets

Local farmers often use fewer pesticides even if not certified organic, and prices are usually lower than supermarkets.

3

Buy in Season

Seasonal produce is more abundant, cheaper, and often requires fewer pesticides since it's growing in optimal conditions.

4

Join a CSA

Community Supported Agriculture programs offer weekly organic produce boxes at significant discounts compared to retail prices.

The Bottom Line

The most important thing is to eat plenty of fruits and vegetables, whether organic or conventional. The health benefits of produce consumption far outweigh any potential risks from pesticide residues.

However, if you're looking to minimize pesticide exposure—especially for children and pregnant women—using the Dirty Dozen and Clean Fifteen lists as a guide can help you make strategic choices without breaking your budget.

Remember: a conventional strawberry is still healthier than no strawberry at all. Use these lists as a helpful tool, not a source of food anxiety.
