Contrary to common misconceptions, canned food can be a healthy choice as it contains many valuable vitamins and minerals, sometimes even more than traditionally stored items. However, it's important to remember about the critical step before opening a can to avoid pathogen transmission.

Remember this essential step when opening canned food

A frequently overlooked error is not wiping the top of the can before opening. We should understand that canned goods travel a long journey before they reach our kitchens and retail shelves. Throughout their storage in warehouses and transportation via trucks or planes, they gather dust and dirt. Therefore, it is crucial to wash the can lids thoroughly before opening to minimize the risk of cross-contamination.

Cross-contamination is a risky process where pathogens are unintentionally transferred from one object or substance to another.

This advice is confirmed by Jamie Mok, a dietitian and spokesperson for the American Academy of Nutrition and Dietetics. Mok urges consumers always to wash and wipe can lids to reduce the spread of germs and bacteria and prevent the onset of foodborne infectious diseases. After all, the dust, grit, and pathogens collected on the lid could contaminate the food inside.

Tips for washing a can to prevent contamination

According to Jamie Mok, following the American Food and Drug Administration guidelines, consumers should thoroughly wash containers, including can lids, with soapy water for at least 20 seconds. Using a scrub brush to clean deep edges or crevices can also be beneficial.

During this process, inspect the can carefully for any signs of spoilage, such as bulges, dents, or rust on the packaging. If the can appears intact and undamaged, rinse it thoroughly with warm water, dry it, and then you can open it safely.

After opening, remember to store the canned food in the refrigerator in glass or plastic containers designed for food storage. Why is this necessary? One key reason is that an opened can may cause particles from the metal packaging to seep into the food.
