What type of bacteria will multiply between 32 and 95 degrees?

The correct choice, which indicates psychotrophs, is based on the specific temperature range in which these bacteria thrive. Psychotrophs are microorganisms that can grow at a wide range of temperatures, typically between 32°F (0°C) and 95°F (35°C). This adaptability allows them to survive in both refrigerated and relatively warm environments, making them particularly concerning in food safety, as they can spoil food even at temperatures that are not optimal for many other bacteria.

In food safety contexts, psychotrophs are often associated with food spoilage, especially in products stored in cool conditions that may not be cold enough to inhibit their growth, such as dairy products, meats, and ready-to-eat meals. Understanding that psychotrophs can thrive in this temperature range is crucial for maintaining proper food storage practices to prevent foodborne illnesses and ensure food quality.
