You can find tons of tips online saying you should always wash your produce. What is the point of it though? I mean with some hard produce, say carrots you can obviously give them a good scrub with a brush and I can see how thoroughly it cleans them. What about soft produce though?
I've just read a question regarding raspberries. The answer was to wash them gently in cold water. I can't imagine that this is actually cleaning them properly. Obviously if they're very dirty, then it'd remove the biggest dirt. Let's say though that there are some bacteria on it or parasite larvea. Obviously gentle dip in cold water won't help, will it?
