Eating food, including bread, beyond its expiry date always comes with some risk. The expiry date on food products is determined based on the manufacturer's estimation of how long the product will retain its quality and safety under normal storage conditions. After the expiry date, the product may begin to degrade, and there is a higher likelihood of microbial growth, which could lead to foodborne illnesses.
Storing bread in the fridge can slow down the growth of molds and bacteria, extending its freshness compared to leaving it at room temperature. However, it's important to note that refrigeration does not guarantee that the bread will remain safe to eat after its expiry date.
Factors such as the initial quality of the bread, how it was handled, and the specific storage conditions in the fridge can all influence how quickly it degrades. Even in the fridge, the bread might become stale, develop off-flavors, or accumulate mold spores, which can be harmful if consumed.
If you're contemplating eating bread past its expiry date, it's essential to assess its appearance, smell, and texture. Discard it immediately if you notice any signs of mold, an off odor, or a significant change in texture, like excessive dryness or stickiness.
Ultimately, to ensure food safety, it's best to adhere to the expiry date guidelines provided by the manufacturer and consume bread before it expires. If you frequently find yourself with leftover bread that you can't consume before it expires, consider freezing it in portions to extend its shelf life.
