Baby Food: How Long It Keeps Once Opened

Baby food is the category where USDA’s clock starts at the lid rather than the receipt: every window here is measured from the moment a jar, pouch, box, or bottle is opened or prepared. It’s also the shortest-window category on the site — opened purées, dinners, fruits, and vegetables are fridge food measured in days, and prepared formula is measured in hours once it’s out of the fridge. FoodKeeper lists no freezer window for any of it, so when a feeding is half finished the honest choices are refrigerate it now or pour it out.
