Food safety is a crucial aspect of maintaining good health, and the handling of cooked foods, particularly meats, can present significant risks if not done properly. Many of us have faced the situation where food, specifically cooked meat like steak, is inadvertently left out overnight. It's common for people to have differing opinions on whether it's safe to eat or not; some, like your husband, may think it's perfectly fine, while others might be hesitant.
The truth lies within the understanding of food safety guidelines and the science behind bacterial growth. It's important to have a clear understanding of what risks are involved and how to avoid potential food-borne illnesses.

Understanding the "Danger Zone" for Bacterial Growth
According to food safety guidelines, the temperature range in which bacteria can grow most rapidly is between 40°F and 140°F (4°C and 60°C). This range is commonly referred to as the "danger zone". Cooked meats, like steak, that are left out at room temperature for more than two hours should be considered risky to eat because they may fall within this danger zone, allowing harmful bacteria to multiply to dangerous levels. Here’s what you need to consider:
1. Time and Temperature
The bacteria that cause food poisoning multiply quickest in the "danger zone" temperature range. If steak is left out for more than two hours at room temperature, it should be discarded. This time is reduced to just one hour if the temperature is above 90°F (32°C), as can happen in hot summer months.
2. Types of Bacteria
Several types of bacteria, including Salmonella and E. coli, can grow on cooked meat that has been improperly stored. These bacteria can cause food poisoning, which might lead to symptoms like nausea, vomiting, diarrhea, and fever.
3. Perishable Nature of Cooked Steak
Cooked steak is considered a perishable item, which means it can spoil quickly. Once it's been cooked, its natural preservation barriers are broken down, making it more susceptible to bacterial growth.
4. Exceptions and Misconceptions
There might be some beliefs or traditional practices that suggest certain foods are safe to leave out, or that certain cooking methods can protect food for longer periods. However, these beliefs don't change the science behind bacterial growth.
5. Reheating Does Not Always Help
While reheating food to the proper temperature can kill some bacteria, it does not eliminate all toxins produced by the bacteria. Some of these toxins can be heat resistant and can still cause food poisoning even after reheating.
6. Good Food Safety Practices
To minimize risk, cooked food should be refrigerated within two hours of cooking. This practice significantly slows bacterial growth and extends the shelf life of the food safely.
7. Trust Your Senses
Even if you are unsure of how long a food item has been out, using your sight, smell, and taste to check for signs of spoilage can offer some indication, although this is not foolproof and harmful bacteria might not be detectable through these senses.

In conclusion, while there may be dissenting opinions in the household, the safest approach is to err on the side of caution. If cooked steak or any other perishable food has been left out overnight, it’s better to discard it rather than risk the health consequences of eating potentially spoiled food. Food safety is all about preventing illness and ensuring that what you eat contributes positively to your health, not detracts from it.
