I have been storing my food this way for years and have never had any problems. Just check your bags from time to time to make sure they are still vacuum sealed. If you notice that any air has escaped then you will need to re-vacuum and seal. However, I have never had to do this.... This method does work for foods you want to store for up to 5 years ... For foods that you want to store for longer term the 5 gallon sealed buckets with oxygen absorbers or mylar bags is the way to go. (Also, throw in a few bay leaves before packing...Bugs hate bay leaves and it will not change the taste or smell of your food. I also put a bay leaf in my vacuum sealed bags for extra protection from bugs)
