The product appears to be an Omega One flake, which surprises me as I didn't think that they allowed re-packaging and selling their product in bulk. Hmmmmm. Also, just as any other food sold in bulk, the quality will depend on how that food has been handled, and stored, and for how long. (especially flake food) The more exposure to light, moisture, and/or heat, the quicker it will degrade.
HTH
