If your beef jerky is in an opened package, transfer the beef jerky AND the packet of desiccant to a zipper baggie and close tightly. Return to the climate-controlled pantry if it will be eaten within seven days. 

If you want to keep beef jerky for up to three weeks, transfer the beef jerky and dessicant into a zipper bag and keep in the back of your refrigerator.

If you want to keep your beef jerky up to a year, move to a freezer zipper bag and transfer to the freezer. Label with the date.

If your store-bought beef jerky is in an UNOPENED, original package, leave it unopened and move it to the pantry, refrigerator or freezer for up to a year.
