Quick answer: Pet food stays safest when it’s stored in its original packaging, kept cool and dry, and used within the right time frame: opened dry food within about 6 weeks, opened cans within about 3 days refrigerated, and wet food in the bowl for no more than about 2 hours. Wash bowls after each meal, wash your hands after handling pet food, and keep the lot number so you can check recalls.
Storage timeline
- Unopened dry food: until the “best by” date, stored cool and dry
- Opened dry food: about 6 weeks, in the original bag inside a sealed container
- Unopened cans: until the “best by” date
- Opened cans: covered in the fridge, usually up to 3 days (check the label)
- Wet food in the bowl: about 2 hours, less in heat. See how long wet food can sit out.
- Treats: follow the package and reseal after each use
- Raw and fresh-refrigerated diets: follow the maker’s instructions strictly, and thaw in the refrigerator
Why keep the original bag
The bag has the lot number and “best by” date you’ll need if there’s a recall. It also has a fat barrier that helps keep food fresh.
Hygiene
- Wash bowls and scoops with hot, soapy water after each use.
- Wash your hands after handling pet food or treats, especially raw diets.
- Don’t use the food bowl as a scoop.
- Keep pet food away from human food prep areas.
Signs food may be spoiled
- Bad or rancid smell
- Mold, moisture, or clumping
- Bulging or damaged cans
- Insects
Recalls
- Check the FDA’s pet food recall list periodically.
- If your pet gets sick after eating a food, save the package and report it to your vet and the FDA.
