According to a Washington Post story:
As many as 6 million prepared meals stockpiled near potential victims of the 2006 hurricane season spoiled in the Gulf Coast heat last summer when the Federal Emergency Management Agency ran short of warehouse and refrigeration space, according to agency officials.
FEMA is taking more than $40 million in food and picking through, trying to find whatever hasn't spoiled, and then tossing the rest. Much of the food ws in the form of military rations that are supposed to last in desert and jungle climates, showing that a Louisiana summer is nothing to trifle with. I'm sure the agency is now contacting some big contractor or other to deliver bags of ice. Lots of them.
