master-cooks | The Problem With Storing An Open Can Of Food In The Fridge

Storing an open can of food in the fridge can lead to several issues affecting both the quality of the food and potentially your health. When a can is opened, its contents are exposed to air and moisture, which can accelerate spoilage. The metal from the can may also start to oxidize, potentially leaching metallic flavors into the food and altering its taste. This is particularly concerning with acidic foods like tomatoes or pineapple, which are more likely to react with the metal. Additionally, an open can in the fridge may not provide an airtight seal, leading to the possibility of bacterial contamination. This can increase the risk of foodborne illnesses if the food is consumed later. Transferring the contents to a glass or plastic airtight container before refrigerating is recommended to maintain freshness, flavor, and safety. Furthermore, storing food in a proper container helps to prevent odors from spreading throughout the fridge, which can otherwise affect the flavors of other foods. By taking these precautions, you can ensure that your leftovers remain both safe to eat and enjoyable, while also promoting better food storage practices in your kitchen.

Today's cans are much safer than in decades past

If you grew up listening to warnings— or at least hearing about them— regarding the dangers of storing food in original cans due to fears of toxic metals leaching into your meals, it's because cans were manufactured quite differently in the past. Up until 1995, cans in the U.S. often contained lead in their seams. So, if your parents or grandparents cautioned you against keeping food in cans, they were not exaggerating. Fortunately, the U.S. has since prohibited the use of lead in cans, although some sources still highlight the presence of BPA and similar chemicals as reasons to opt for alternative storage containers.

Generally, canned food is very safe, convenient, and has a long shelf life, significantly transforming our shopping and eating habits. However, there are still some sensible storage guidelines to follow—both before and after opening the cans. By selecting cans that are free from dents or damage, storing them properly, and transferring leftovers into airtight containers, you can make delicious (and often just as nutritious as fresh options) canned foods a regular part of your kitchen.
