Welcome, Tin! Personally I wouldn't worry about that but I guess if things got bad enough it could be an issue. To start you'd probably want to heat & eat your food by a window so the food aroma didn't waft down the hallways. The best bet would be to clean the empty packages as well as you can (depending on if there's still running water) and shred the packages into thin strips (a shredder would be ideal). Maybe put the shreds/confetti into zip lock bags and stuff them into black garbage bags. Dump them in the dumpster as inconspicuously as possible (eg middle of the night, early in the AM, etc).

It's good to have you here at ETS! I hope you stick around to learn and share.
