I’ve used white rice 5 or 6 years after.
I repack it in quart ziploc bags, nest those in gallon ziploc bags and freeze for 10 days to kill bugs and their eggs.
Then it’s on the shelf in my pantry on the north side of my house.
Had no problem with it. A whole 2 gallon bags of quart bags got ‘hidden’ behind some plumbing supplies hubby laid there and wasn’t discovered until a few years later when we needed the plumbing supplies again LOL. Put it in the crock pot with a whole chicken, some carrot coins and onions and some poultry spice. Yummy.
Tonight they were out of pinto beans (25 lb. bags) and the 6 gallon food storage bucket were all gone.
Everything else was fairly normal.
