Food after P-Day
After P-Day, and the power going out pretty much nation wide, most food stores would spoil and rot quick enough to be made unusable due to lack of refrigeration. Anything that wasn't tightly sealed would also stand the risk of getting infectious fluids in it. Foods such as meats, milk, butter, eggs, and similar would go bad within the day without being kept cold. Without proper seals, any opened packages would more then likely come in contact with contamination. For the first few months, people would have had to live off of food stores that they had, or salvage unspoiled, sealed foods from anywhere near by.
