Opened Wet Pet Food: Save the Portion Still in the Pack
PARTNER Editorial TeamWhen a can or pouch holds more than one meal, set aside the next portion before the bowl goes down. Refrigerate the unused food promptly or discard it. Food that has been licked, warmed in the bowl, or mixed into another meal is a poor candidate to save; discarding it is the straightforward choice when you can’t account for how it was handled.
Separate the two portions at the counter
Use a clean utensil to move the amount you want to serve into the bowl. Cover or seal the unused portion and put it in the fridge while the pet eats. The FDA’s pet food storage guidance recommends a refrigerator set at 40°F or below for unused or leftover canned and pouched pet food. If you transfer it to another container, label it with the recipe and opening time, and keep the package or take a clear photo of the lot and date. That way nobody has to guess whether two containers hold the same food or which was opened first.
| Situation | Practical choice |
|---|---|
| Clean portion set aside when opened | Seal it, label it and refrigerate it promptly. |
| Food left in a dish your pet ate from | Discard it if its handling or time out is uncertain; don’t mix it into the reserved portion. |
| Unknown opening time or uncertain refrigerator temperature | Don’t use appearance or smell as the only check. Set it aside and serve food you can identify. |
Read the instruction for that specific food
The number of days to keep a refrigerated portion should come from the package or the maker. A best-by date on the outside doesn’t tell you how many meals you can serve after opening. If you keep finding half a pouch left and there’s no clear storage instruction, ask the company or choose a package size closer to what you use in one meal.
If the refrigerator lost power, use the outage guide for opened wet food. The decision then depends on how cold the food stayed, rather than how neatly it was covered.
