How long after preparation can refrigerated food be sold or served if stored safely?

The correct answer is based on food safety guidelines that specify how long refrigerated food can be safely consumed after preparation. Refrigerated food, when stored at proper temperatures (below 40°F or 4°C), can generally be held for up to 7 days. This timeframe helps ensure that any potential bacterial growth is kept to a minimum, allowing the food to remain safe for consumption.

When food is prepared, it enters a critical time and temperature zone where it is most susceptible to contamination and spoilage. Consuming refrigerated food after 7 days increases the risk of foodborne illnesses due to the potential for bacterial growth that occurs despite being stored in the refrigerator. Hence, a 7-day limit is a widely accepted guideline among food safety authorities, including the USDA and the FDA, promoting safe food handling practices in order to protect public health.

The other choices reflect longer times which may pose safety risks, as food quality and safety can deteriorate beyond 7 days, leading to possible health hazards if consumed.
