Today, Luther says she keeps a pantry with three different levels of “defense.” The first consists of boxes of cereal, frozen foods, and other items you might fall back on if you couldn’t make it to the grocery store for a week or two. The second, her “short-term” food storage, includes canned goods and other items with a longer shelf life — “Stuff you’d use if perhaps you lost a stream of income and times were tight for a few months,” Luther explains. The third is her long-term food storage: Mylar bags full of dry goods like beans, rice, and wheatberries, as well as some freeze-dried fruits, vegetables, and meat. Layer three, she says, is for “a situation in which all hell has broken loose.”
When it burns, EPS produces heavy, acrid and toxic smoke. This obviously presents another serious problem when you are in a confined space, from which there is no escape. Even a small event in which this material merely smoldered with no open flame can/would have dire consequences for the occupants. Exposure to the heavy smoke generated, even if only for a few minutes, has been shown to be lethal.
Still, these extraterrestrial-looking foodstuffs seem to be having something of a moment: For the past four years, Costco has been selling pallets of shriveled vegetables, fruits, grains, and meats that promise to feed a single family for up to a year—and if you’re not a member, you can purchase similar survival kits, many of which boast a 20- to 30-year shelf life, at Walmart and Target. One top seller, Wise Company, saw its sales nearly double over the past four years, reaching around $75 million, according to a Bloomberg Businessweek cover story last November. The company’s CEO, Jack Shields, told me he estimates the industry as a whole generates between $400 and $450 million annually in retail.
