LONGER-TERM FOOD SUPPLY
Longer-Term Storage—30 Years or More
packaged, low-moisture foods stored at room temperature or cooler
(75°F/24°C or lower) remain nutritious and edible much longer than
previously thought according to findings of recent scientific studies.
Estimated shelf life for many products has increased to 30 years or
more (see chart for new estimates of shelf life). Previous estimates of
longevity were based on "best-if-used-by" recommendations and
experience. Though not studied, sugar, salt, baking soda (essential for
soaking beans), and vitamin C in tablet form also store well long-term.
Some basic foods do need more frequent rotation, such as vegetable oil
every 1 to 2 years.
there is a decline in nutritional
quality and taste over time, depending on the original quality of food
and how it was processed, packaged, and stored, the studies show that
even after being stored long-term, the food will help sustain life in

containers, used with oxygen absorber packets, eliminate
food-borne insects and help preserve nutritional quality and
certain conditions, you can also use plastic buckets for longer-term
wheat, dry beans, and other dry products.
Botulism poisoning may result if moist products are stored in packaging
that reduces oxygen. When stored in airtight containers with oxygen
products must be dry (about 10% or less moisture content).
life can be significantly impacted by the following conditions:
and rodents: Protect products stored in foil pouches and
PETE bottles from rodent and insect damage.
Store products at a temperature of 75°F/24°C or lower whenever
possible. If storage temperatures are higher, rotate products as needed
to maintain quality.
- Moisture: Keep
storage areas dry. It is best to keep containers off of the floor to
allow for air circulation.
- Light: Protect
cooking oil and products stored in PETE bottles from light.
