Many of the top questions we get in the Harrison's Technical Dept. have to do with the infamous brown Harrison's bag. Should the food be repackaged into plastic bags or Tupperware? Should the food be frozen in the bag, etc.?

| The current Harrison's Bird Foods bag |
As Harrison's Bird Foods are a certified organic product and do not contain artificial preservatives we asked bag-makers to develope a bag that works to preserve freshness. The "bag" itself is indeed the preservative.
It should be noted that a lot of work went into developing this bag. When the Harrison's triple-layered plastic/foil/paper barrier bag was introduced in the 90's this type of packaging really had yet to be seen elsewhere. We worked closely with bag manufacturers to create a very specific type of bag. The plastic liner is an excellent moisture barrier, so why not just use a plastic zip-lock baggie (Harrison's actually used to ship in a plastic baggie, inside a cloth bag. Remember those - see pic below?). The two main problems with a typical zip baggie is that they do not block light, nor do they stop the permiation of oxygen, which are two of main causes of foods going stale (rancidity).
Where plastic fails, foil excells. The second layer of the Harrison's bag is made of foil which really does the trick in keeping foods fresh. Foil blocks light and keeps oxygen out.
In recent years we did away with the paper outer layer. Now bag companies are able to print faux-kraft paper look right on to the bag itself without having to waste paper.
So what about all the other popular (re)packaging option?
-
Zip Lock baggie: plastic does not block light or oxygen.
-
Tupperware: only partially blocks light, does not block oxygen and a half-empty container is also half full of oxygen.
-
Glass jar: does not block light. Glass does block oxygen but again a half-empty container is also half-full of oxygen.

The bag that the food comes in really is the best option for storing Harrison's certified organic foods.
As there are no artificial preseveratives in Harrison's, the manner in which you purchase and store the foods is very important in regard to keeping fresh foods.
Some simple recommendations can be helpful...
- Don't buy bags that hold more food than you can feed in 6 weeks (after opening). A 5lb bag of food is far too much for a parakeet. At some point you will either be feeding stale food or tossing several pounds of food. For small birds purchase small packages.
- Store bags in cool dry place that is free of rodents who can chew through bags.
- Once bag is opened squeeze air out, zip shut and store in the freezer or refrigerator. Cold temperatures slow the natural breakdown processes of all foods.
If the zipper is accidentally removed or damaged you can simply squeeze out the air, roll down and "chip clip" the bag shut. Oxygen will not force it's way in through the roll-down.
Pay attention to the "use-before" date on all Harrison's bags. Do not feed expired foods regardless of how they are stored. Do not purchase food that is not in the original packaging. Please report any instances of this practice (800-346-0269 or

As you can see, the bag has come a long way over the years. In its current form it really does work wonders in keeping bird food fresh!
