Conventional Crops most likely to be Contaminated

As a result of standard conventional (not organic) farming practices certain crops are very likely to be contaminated with a variety of pesticides, while other crops remain relatively clean of pesticides. For the contaminated crops it is best to buy these crops from organic farms. Here's a good read on what is 'Organic', see Organic Foods for Increased Human Health.

It's important for parents to know which conventional crops contain pesticides as children may be especially sensitive to health risks posed by pesticides as their internal organs are still developing and maturing. Pesticides may harm an infant or developing child by blocking the absorption of important food nutrients necessary for normal healthy growth.

Here is a list published by the EWG of crops most likely to contain pesticides:

  • apples
  • celery
  • bell peppers
  • peaches
  • strawberries
  • nectaries
  • grapes
  • spinach
  • lettuce
  • cucumbers
  • potatoes
  • green beans
  • blueberries
  • kale, collards, leafy greens
  • Conventional Crops most likely to be Clean

    Here's a list crops most likely to be mostly pesticide free even when grown with standard conventional farming (not organic) practices:

  • onions
  • sweet corn
  • avocado
  • cabbage
  • sweet peas
  • asparagus
  • mangoes
  • eggplant
  • kiwis
  • cantaloupe
  • sweet potatoes
  • grapefruit
  • watermelon
  • mushrooms
  • As these crops are mostly free of pesticides, it is not essential to buy these crops organically grown.
