Homemade Jerky or Homemade Beef Jerky will last for up to 2 months in airtight sealed packages.
If you just store the homemade jerky in Ziploc bags or bags that are not airtight then the beef Jerky will only last for a week.
Storing the beef jerky in airtight packages helps to keep the bacteria out of the beef jerky and makes it last much longer.
It's best to eat the beef jerky within a week if you store it in regular bags or containers.
If the beef jerky is sealed in airtight packages with the air removed then eat it within a few months although it will usually remain safe to eat for awhile after that.
