I bought a bunch of rice, and all that happened was little rice bugs started living in it, so I had to throw it all away. But if there were a rice shortage, I would probably have eaten it.
If you freeze it for 24 hours it will kill them off. Can be a good idea to do that when it comes into the house anyway as they might be in there already.
Easy enough to separate them out of the rice after freezing too.
For the same reason (kill bugs), the same thing is recommended when you buy flour. Put it in the freezer for 24+ hours, then take it out and store at room temperature.
