Harrison's Bird Foods is committed to protecting your bird from artificial preservatives which can be harmful to its health, and therefore none are included in its foods.
Here are some suggestions to keep your food fresh:
* - We therefore recommend that you only buy a bag which provides the amount of food that your bird(s) will eat in this period. For one or two small birds (likely eating Fine or Superfine) this will probably be the 454g bags. For one or two larger birds (likely eating the Coarse) this will probably be the 2.27kg bags. The 11.3kg bags are most suitable for owners with 6+ larger birds, or large collections of smaller birds.
