A: Thanks for reaching out to us. Ideally, food should be consumed within 5-6 weeks from when opening the bag to ensure freshness. When the package is closed tightly and stored in a cool, dry place, the product will remain fresh and nutritionally balanced until the Best If Used By Date on the package. Remember, pet food is food. It should be stored in ways that are similar to how human food is stored. Store all pet food in a cool, dry location that is off the floor. It is not recommended to store food in the garage or outside since those locations often lead to insect infestation. When possible, store food in the original bag and within a plastic or metal bin with lid. - The ONE Team
