By the time 200 years rolls around the food is basically gone. Still probably wouldnt smell good because of the ambient environment but there would be nothing close to rotting food left.

To be fair, the Fallout universe doesn't follow real world physics. If it did, the world wouldn't be a mostly barren wasteland. Plants don't give a fuck about radiation; just look at Chernobyl.

There's also the fact that they have nuclear-powered batteries that are still holding a charge, and many unmaintained buildings are still intact instead of being just giant piles of decomposing steel. (And obviously there wouldn't be any mutant 2-headed oxen, giant cockroaches, super mutants, ghouls, etc.) The Fallout universe runs on 1950s sci-fi physics.
