The simple answer is no, you can’t. In food safety, the amount of time food spends at specific temperature ranges is cumulative. You can’t simply “reset the clock” by recooking it. The only way to slow down the clock is to keep food at a safe temperature, like freezing it.
Behind this idea is the truth that cooking doesn’t sterilize food. Proper cooking only reduces bacteria to a certain level, often around 1 in 100,000. Food safety agencies haven’t made models for bacterial growth after reheating potentially unsafe food. It’s quite possible that after reheating, the bacteria count might be higher than it was after the first cooking.

Even if the difference seems small, bacterial growth is exponential. A slight change in the initial conditions can lead to huge differences after just a few hours. This exponential growth poses a significant risk.
Furthermore, some bacteria produce toxins that are not destroyed by heat. These toxins can cause illness even if the bacteria themselves are killed during recooking. The presence of these toxins represents a serious health hazard.
It’s important to avoid inventing your own food safety methods. Bacterial growth is incredibly complex. Trying to predict the outcome using common sense and simple calculations is unreliable, much like trying to predict the weather a week in advance based on intuition. Instead, rely on the expertise of scientists with supercomputers and extensive scientific knowledge.
Therefore, when it comes to food safety, erring on the side of caution is crucial. If you have doubts about whether food is safe to eat, it’s always best to discard it rather than risk food poisoning. Trust in established food safety guidelines and avoid taking unnecessary chances with your health.
