I accidentally left my groceries in a hot car for a couple of hours, including 2 packages of frozen vegetables and a package of hot dogs. The vegetables packages are predictably un-frozen but but still cold to the touch, so I assume I can re-freeze them without a problem. The hot dogs warmed to approximately room temperature (they were sitting on the veggies, which seems to have kept them cool on one side). Are they still safe to eat, do you think, or should I throw them out?
