My sister-in-law (thank you) sent me a link to a CNN article examining the level of pesticide residues found on food crops, things such as Celery, Peaches, Strawberries, Apples, Blueberries, Nectarines, Sweet bell peppers, Spinach, Kale and other brassicas, Cherries, Potatoes, Grapes, Lettuce. To find out more have a look, here:
CNN "Dirty Dozen"
I grow some of those, and everything I grow is produced organically, so I'm quite happy to eat straight from the garden without washing (the veggies I mean, not me!) Organic farming food production has been around probably since the dawn of agriculture, so our bodies are well adapted to healthily produced food; only time (and lots of it) will tell what the long term effects on our species might be from ingesting pesticides and insecticides. Until we know better the consequences, why take the chance, grow organic if you can and shop organic if you can't grow it.
