What is the optimal temperature range for mesophilic bacteria to grow?

Mesophilic bacteria thrive in a temperature range that typically falls between 68°F and 113°F. This range is ideal for their growth because it provides the warmth necessary for optimal metabolic processes without being too hot, which would inhibit their development or kill them.

Mesophilic bacteria include many types of bacteria that are commonly found in foods, and their growth can lead to food spoilage if food is not kept at appropriate temperatures. Understanding this temperature range is crucial for food safety practices, especially when cooking, storing, and holding food, as it helps in preventing the growth of harmful bacteria that can cause foodborne illnesses.

The other ranges mentioned are either too cold or too hot for mesophilic bacteria. The lowest range, below 32°F, would significantly slow down or halt their growth, while the highest range over 122°F would generally be lethal for these types of bacteria. Thus, knowing that the prime growth temperature for mesophilic bacteria is within the 68°F to 113°F range is critical for anyone involved in food management or safety.
