Pet food storage: keep it fresh, safe, and traceable
Pet food spoils more often than owners realize, and recalls hit traceability hard. A clean storage routine and a 30-second record-keeping habit protect both the food and the dog or cat eating it.

Quick answer: Store dry food in the original bag inside an airtight container (the bag carries the lot number and best-by date). Refrigerate opened wet food and use within 2 days. Photograph the bag’s lot number and best-by date when you open it; that record matters if there is a recall.
Why storage matters
Dry pet food is shelf-stable but its fats oxidize over weeks. Improper storage accelerates rancidity, which is not always visible. Wet food spoils within days once opened. Both can carry contamination if exposed to pests, moisture, or unwashed scoops.
Storage also matters for recalls — the FDA tracks pet food recalls by lot number and best-by date. A photo of the bag at the moment of opening makes a recall response immediate rather than retrospective.
Dry food storage
- Keep dry food in its original bag. The bag is engineered for food contact; the lot number and best-by date live on it.
- Place the sealed bag inside an airtight container if you want pest protection — do not pour kibble directly into the container.
- Use within 6 weeks of opening for best freshness.
- Store cool and dry — not in a garage that hits 90°F in summer.
- Wash the scoop weekly; do not leave a scoop in the bag long term.
Wet food storage
Refrigerate opened cans or pouches in a sealed container; use within 2 days. Do not leave wet food out for more than 2 to 4 hours at room temperature.
Some pet food brands recommend warming refrigerated wet food briefly before serving — cold food can reduce appetite, especially in cats.
Lot-number record habit
When you open a new bag or case, photograph the label showing brand, product, lot number, and best-by date. Add a one-line note: opened YYYY-MM-DD.
If the FDA or the manufacturer announces a recall, you can match the recall to your lot in under a minute.
Pests and contamination
Mice, moths, and beetles are common pet-food pests. The original bag inside a container is the simplest defense. Wash containers between bags. Inspect for moisture, mold, or webbing — signs of compromise.
If you see anything off (smell, texture, color), discard, photograph the lot information, and report to the manufacturer and the FDA via the SafetyReporting.fda.gov portal.
How Driyu fits
A Driyu pet profile carries current diet (brand, food, treat list, prescribed diet flag). When a recall hits, the profile’s diet field combined with your saved photo of the lot makes the response immediate. Your vet sees the same record at every visit.

Frequently asked questions
Can I freeze pet food?
Some wet foods freeze well; check with the manufacturer. Frozen wet food extends usable life when thawed in the fridge. Dry food does not benefit from freezing.
How long is dry food good after opening?
Most manufacturers recommend using within 4 to 6 weeks of opening. Smaller bag sizes are friendlier to single-pet households.
Is it safe to mix old food with new?
When transitioning between bags of the same product, yes. When transitioning to a new product, follow a slow 10-day transition.
What should I do if I suspect a recall?
Stop feeding the food, save the bag (lot and best-by visible), call your vet, and report to the FDA. Photograph the bag if you have to discard it.
