Hello, I'm an expert in food safety and nutrition. When it comes to consuming yogurt that has been left out overnight, there are a few factors to consider.

Firstly, the safety of yogurt depends on the temperature at which it was left out. Yogurt is a perishable food item that ideally should be stored at a temperature between 35°F and 41°F (2°C and 5°C). If yogurt is left out at room temperature, which is typically around 68°F to 77°F (20°C to 25°C), it can lead to the growth of bacteria, including harmful pathogens.

Secondly, the length of time the yogurt has been at room temperature is crucial. According to the USDA, perishable foods should not be left out for more than two hours at room temperature. If the temperature is above 90°F (32°C), the safe time frame is reduced to one hour.

Lastly, the appearance and smell of the yogurt are also indicators. If the yogurt has an off smell, mold, or an unusual texture, it should not be consumed.

In conclusion, if yogurt has been left out overnight at room temperature, it is generally not safe to eat due to the potential for bacterial growth. It's always better to err on the side of caution when it comes to food safety.
