You should also label and date each container so that you can keep track of how long it has been stored. Additionally, store raw meat, poultry, and seafood in sealed containers to prevent cross-contamination with other foods. By following proper storage and handling practices, you can help extend the shelf life of your food and reduce the risk of spoilage.
Can I still eat food that has been stored in the refrigerator for a long time if it looks and smells fine?
Even if food looks and smells fine, it’s not always safe to eat if it has been stored in the refrigerator for a long time. The risk of foodborne illness increases with the length of time food is stored, even if it appears to be fresh. This is because some types of bacteria, like Listeria and Salmonella, can grow slowly on food even at refrigerated temperatures. These bacteria can cause foodborne illness, even if the food looks and smells fine.
To be safe, it’s best to follow the “use by” or “best by” dates on food packaging, and discard any food that has been stored for longer than the recommended time. If you’re unsure whether food is still safe to eat, it’s better to err on the side of caution and discard it. You should also be aware of any changes in the food’s texture, consistency, or appearance, as these can be indications of spoilage.
