ALWAYS FREEZE ANYTHING YOU PLAN TO DRY STORE for AT LEAST THREE DAYS TO KILL CRITTERS. Rice, beans, flour, wheat berries, grits (NOT SUGAR, unless you want a concrete BLOCK when you are done)....Even if you are going to store it in your pantry for everyday use in "airtight" Tupperware, sometimes a "BLOOM" of DISgusting little bugs that crawled into your bag in the warehouse and can happen INSIDE the container. If you buy a #50 bag of rice or wheat, it will be HUGE, so freeze it in batches, if you must. BUT DO FREEZE IT BEFORE YOU STORE IT.
The tips about LDS folks knowing their stuff is TRUE. They are WAY ahead of the rest of us.
ALSO---Check out this guy's archives on food storage. Ignore the stuff that will scare you (though I think he is 95% SPOT ON), if you need to, but
he knows his stuff on food storage....
http://www.survivalblog.com His blog archives suggest suppliers of food grade buckets and storage needs as well as charts that help you cycle what you have stored.
MAKE SURE that if you decide to LONG TERM (up to three years on the OUTSIDE) you use FOOD GRADE BUCKETS and oxygen absorbers with mylar bags inside the food grade buckets (marked NSF). DO NOT buy plain buckets from WalMart, or somehwere. The mold releasing agents that are used on these "paint grade" buckets are NOT FOOD SAFE with ANY amount of washing.
Pardon my caps...its a crutch....I am not shouting, but I am too lazy to italicize... heehee.
