A practical four-card checklist for building a three-day shelf-stable food buffer for four people: a no-cook shopping grid, storage and rotation rules, and a fast safety check for damaged or flood-exposed packages. 1234
Ready.gov's official baseline is at least a several-day supply of non-perishable food. The page specifically points to foods that need no refrigeration, cooking, water, or special preparation, plus a manual can opener and eating utensils. The 36-portion grid in the images is a practical shopping start for four people who plan three eating moments per day; it is a household planning aid, not a federal ration standard. Adjust the portions for normal appetite, allergies, medical diets, infants, and older adults. 1
Keep canned food in a cool, dry place, and keep boxed food in tightly closed plastic or metal containers. Keep package dates visible, use the earliest dates first, replace expired items, and review the kit at least yearly as the household changes. 2
Use the safety sort before opening a package. CDC says to discard food that touched floodwater, food in bulging, open, or damaged containers, and food that spurts liquid or foam or shows mold, discoloration, or an unusual smell. Never taste food as a safety test. Refrigerate canned or pickled foods after opening. 34
