A local feed store has Mazuri 9F in stock for a great price, but they only sell the big 50 Lb bags of it. I'm just starting up a small ASF breeding colony, and would like to know how long the shelf life on lab block is. What is the best way to store it? (In the bag/tightly sealed plastic tub/refrigerated/etc.)

Honestly the price is so good I might even be willing to accept some loss if need be.

Thanks.
