Catmae : Are they not supposed to go bad...ever?
@Amanda79 : Yeah, it's just kind of been an urban legend of sorts. Here are excerpts from a couple of different articles:
Urban legend has long deemed Twinkies the cockroaches of the snack food world, a treat that can survive for decades, what humanity would have left to eat come the apocalypse. The true shelf life - which used to be 26 days - seems somewhat less impressive by comparison.
A common urban legend claims that Twinkies have an infinite shelf life, and can last unspoiled for a relatively long time of ten, fifty, or one hundred years due to the chemicals used in their production. The 2012 Super Bowl Chevy Silverado Apocalypse commercial also gives a nod to the Twinkie's reputed durability.
