Right now I am storing my sugars & flour in a rubbermaid container. Do I need to get something specifically made to store food? Do I need to keep my flour and sugars seperate?
Thanks!

You should be using containers that are NSF rated (rated for food safety). What do you mean by "separate", 'coz I assume they're already in separate containers?

Thanks! I will look into getting some NSF rated storage.
I think I'm doing it all wrong right now I've got the pwd sugar and white sugar in their bags, in the rubbermaid tub and the flour is in another tub. I guessing when I get the NSF containers that I'll pour them into their own containers - one for pwd sugar, one for white sugar and one for flour.
Is that more clear? Sorry, most of the time I'm trying to type while my kids are trying to get my attention away from the computer

Nothing wrong w/keeping the items in their original pkg'ing. You are doing it just fine. Are you a licensed shop that the HD will come ck'ing on?

I use 5 gallon buckets lined with mylar, just like you would for long term food storage (except that I don't heat-seal the bags.) I try to get my flour out of the original bags, because bugs like to lay their eggs in the seams.
Of course, it takes me a while to use up a 50 pound bag of flour.
