Start by checking whether the product is shelf stable. Some canned foods require refrigeration even before opening and are labeled “Keep Refrigerated.” The following U.S. household guidance concerns commercially canned shelf-stable foods. USDA — introduction.

Unopened storage

Keep shelf-stable cans in a cool, dry place, away from the stove, sink, damp storage and temperature extremes. USDA says temperatures below 85°F (≈29°C) are best. Container condition and storage history still matter. Will commercially canned foods last forever?.

Different foods have different windows

Low-acid canned foods, such as meat, non-tomato soups and many vegetables: 2–5 years on the shelf; 3–4 days refrigerated after opening. Shelf Stable Food Storage Chart — Low-acid canned goods.
High-acid canned foods, such as tomatoes, many fruits and vinegar-treated foods: 12–18 months on the shelf; 5–7 days refrigerated after opening. These rows do not establish a universal interval for every canned recipe or damaged container. Shelf Stable Food Storage Chart — High-acid canned goods.

May leftovers stay in the can?

Yes. USDA permits refrigerating unused canned food in the can. Moving it to a glass or plastic storage container helps preserve quality and flavor; it is not a universal safety requirement to transfer it. After opening canned foods, is it safe to refrigerate the unused food in the can?.

Refrigerate food that needs cold storage promptly and keep it covered. Keep the refrigerator at 40°F (4°C) or below. Follow the product's storage instructions. FDA — Storage Basics / Refrigeration Tips.

Damaged and suspicious cans

Discard bulging, leaking, heavily rusted or deeply dented cans. USDA distinguishes a small dent on an otherwise sound can from a deep dent, particularly at a seam. Do not taste suspicious canned food to decide whether it is safe. Rusted cans / Dented cans / Danger of botulism.
