I found this interesting, because, if you knew the truth, you'd realise almost nothing is organic as claimed.
The rule is that as long as TO THE BEST OF YOUR KNOWLEDGE you add nothing chemical or unnatural to a process, then you can claim its organic.
It's quite possible that further down the chain, several processes earlier, something non- organic occurred, but as long as you dont know about it, then you're organic.
Take food. It might have been grown in an 'organic' way, but its possible that chemical processes were used making the fertiliser thats in the compost. So its hardly organic, but the seller of the food can claim 'organic' because he has no connection or knowledge of the fertiliser process.
