For a single, wrapped sandwich, how long can it be refrigerated before it has to be thrown out?

A single, wrapped sandwich can typically be refrigerated safely for up to 7 days before it should be discarded. This timeframe is based on food safety guidelines that help prevent the growth of bacteria and the risk of foodborne illnesses.

When sandwiches are prepared, especially those containing perishable ingredients like deli meats, cheeses, or spreads, it's important to store them properly. Refrigeration slows down the growth of harmful pathogens; however, after a week, the risk increases as the food continues to age, losing both quality and safety.

In contrast, options suggesting longer storage times, such as 10 days, are outside the recommended safety practices for maintaining food hygiene and preventing potential health risks. Choosing a timeframe beyond 7 days would not align with safe food handling guidelines established by food safety organizations.
