If the power grid goes down and water isn’t running, sanitation and waste removal becomes something of value as it can lead to cross-contamination of the foodstuffs and water. Sanitation is of utmost importance to the successful storage of foodstuff and necessities for a proper storage shelter. Things like baby wipes can be extremely assistive in keeping the germs at bay, and they can be thrown in the fire afterward.

Freeze-dried food is nothing new. As early as the 13th century, the ancient Quechua and Aymara people of Bolivia and Peru pioneered a form of the process by exposing potatoes to the freezing temperatures of the Andes overnight, then drying them in the sun. In 1937, Nestlé used industrial technology to create the world’s first freeze-dried coffee, and in the 60s and 70s, the US military shipped freeze-dried food rations to the troops in Vietnam.
