food - Does "Nivdak" flour, grains, beans or pasta exist?

I know Bodek, among other brands sells pre-checked (for bugs, worms, etc.) produce. However, I have not seen any commercially available pre-checked rice, barley (etc. - pretty much any grain that is subject to having worms, bugs, moths, etc.) or flour and pasta. Does it exist? If so, where can I obtain it?

I am not particularly machmir on inspecting grains under an X-ray light, but I hate having moths flying around my cupboard or worms crawling in the rice a few weeks after I buy these things.
