Strict Mormons keep a year's supply of basic foods in storage. At university, married couples could get temporary university housing which was raised off the ground, leaving a space beneath. One Mormon couple put their supply in this crawl-storage space and we joked about the increasing protein content and when it would crawl away. This was in Austin, Texas- hot and sometimes wet.

Re Sorcha's comments about freezing products made with grains, "whut folks don't know won't hurt 'em." The top grade wheat standard specifies a count of no more than one specimen of animal filth (rat dropping usu.) and 3 unknowns per kilogram, and no more than 31 insect-damaged kernels per kilogram. I remember that over 50 years ago, the number of rat droppings allowed in test samples was 9 per 100 grams. Weevil eggs probably would count as unknowns (or perhaps too small to be noticed?).
