> ...frozen meat stays good literally forever. Can you please point me to where this is investigated? I know rough vacuum-grade vacuum-packed frozen meat rates a 3-year shelf life [1]. I've yet to find information beyond rough vacuum [2], though. I would imagine ultra-high grade vacuum, in a retort bag, in a medical-grade freezer (-140 to -150° C [3], well beyond even commercial food deep freezers in the -30 to -50° C range) can extend that shelf life, but I've never found anyone who experimented and wrote it up. Flour can be stored indefinitely in the freezer supposedly [4], but I haven't seen anyone investigate vacuum-sealed, oxygen-absorbed, frozen flour shelf life. Whole wheatberries when vacuum sealed with nitrogen flush will keep for 25 years at room temperature, don't know what adding freezing will do.

>> I know rough vacuum-grade vacuum-packed frozen meat rates a 3-year shelf life That is the number for taste, not food safety. There is lots of guidance that meet is "good" for a few months to a few years. But it is also true that people have eaten mammoth meat frozen for thousands of years. The reality is that long-frozen meat will not taste as good as meat only frozen a few days. >>Because freezing keeps food safe almost indefinitely, recommended storage times are for quality only. Refer to the freezer storage chart at the end of this document, which lists optimum freezing times for best quality. https://www.fsis.usda.gov/wps/portal/fsis/topics/food-safety-education/get-answers/food-safety-fact-sheets/safe-food-handling/freezing-and-food-safety/ct_index https://www.fsis.usda.gov/wps/portal/fsis/topics/food-safety...
