I grow vegetables and fruit in my backyard. Everything is grown organically so I don't have any concerns with pesticide or chemicals on my edible fruits and vegetables. However, they do get exposed to insects and other animals (squirrels). I am not sure if insects lay eggs on my leafy vegetables or some of them get eaten by caterpillars. Whatever the case may be, I would like to know what care I need to take prior to consuming these fruits and vegetables. I am growing leaf vegetables (lettuce, kale), root vegetables (beet, carrot), tomatoes, zuccinni, cucumbers, peppers, apple, pear, grapes, etc.
Just wash them all in clean tapwater - the hardest are the leafy greens, so the way to do that is immersion in a sink full of water, then picking out the leaves and running them directly under the tap, at the same time as inspecting for eggs and caterpillars. Then a salad spinner if you've got one, or just leave them to drain down in a colander. You may need a vegetable scrubbing brush for the carrots if you're not going to peel them before cooking.
If you subscribe to the hygiene hypothesis, then there's no need to wash anything.
If you're not keen on eating insects and eggs, then a good immersion in warm salty water removes insects, and inspection is needed to remove eggs. Insects are a good source of vitamin B12 for those who are strict vegetarians.
