Follow the label for that food
Storage directions can vary, so use the instructions on the package as your guide. Keep the label, date information, and lot details with the food in case you need to refer to them later.
Keep the package closed and dry
Close the bag securely after serving and store it in a cool, dry place away from direct sun and moisture. If you use a separate container, keep the food in its original bag inside it and make sure the container is clean and dry.
Use a clean scoop and finish the food already in the container before adding more. Check the package before serving; if it is damaged or the food seems unusual, set it aside and contact the food maker for advice.
