The USDA confirms that storing leftover canned food in the open can in the refrigerator is safe, Mathrubhumi reports. Modern cans are sealed with steel layers and have an inner polymer coating, but once opened, the exposed rim and metal spoons can cause food to taste metallic. Acidic and salty foods like tomato paste or pickles are most affected as they cause faster metal leaching, though the food remains safe under normal fridge storage. To preserve taste, Mathrubhumi advises transferring leftovers to airtight glass or plastic containers immediately, and using them within 7-10 days.
