(KTVI) - Apples top the dirty dozen list of fruits and vegetables containing pesticide residue. So what are you to do? The answer - clean it as well as you can before eating.

Dr. Alex Vidan from Vidan Family Chiropractic went through the rest of the dirty dozen with John Pertzborn. Vidan said patients regularly ask him if buying organic is necessary and if so what vegetables or fruits they should spend their money on.

This is Vidan's list of what to buy and why -

The Dirty Dozen:

  • Apples
  • Grapes
  • Celery
  • Cherry tomatoes
  • Sweet bell peppers
  • Cucumbers
  • Hot peppers
  • Imported nectarines
  • Peaches
  • Potatoes
  • Spinach
  • Strawberries


A single grape tested positive for 15 pesticides. The same was true for a single sweet bell pepper. Single samples of celery, cherry tomatoes and sweet bell peppers tested positive for 13 different pesticides, each.
The Clean fifteen are products that are least likely to be contaminated.

The Clean Fifteen:

  • Asparagus
  • Avocados
  • Cabbage
  • Cantaloupe
  • Sweet corn
  • Eggplant
  • Grapefruit
  • Kiwi
  • Mangos
  • Mushrooms
  • Onion
  • Papaya
  • Pineapple
  • Frozen sweet peas
  • Sweet potatoes


Multiple pesticide residues are extremely rare on Clean Fifteen™ vegetables. Seven percent of samples had just one pesticide detected.

Pesticides are toxic. U.S. and international government agencies have acknowledged links between different pesticides and a variety of health problems, including:

  • brain and nervous system toxicity
  • cancer
  • hormone disruption
  • skin, eye and lung irritation
