What type of bacteria can grow at refrigeration temperatures?

Listeria monocytogenes is a type of bacteria that can grow at refrigeration temperatures, making it particularly concerning in food service and safety. This bacterium is known for its ability to survive and even thrive in cool environments, such as those found in refrigerators, where many other bacteria would become dormant or die. This characteristic allows Listeria to multiply on ready-to-eat foods, deli meats, dairy products, and unpasteurized products, posing a significant risk, especially for vulnerable populations such as pregnant women, newborns, the elderly, and those with weakened immune systems.

Identifying Listeria's unique ability to grow in cold temperatures underscores the importance of maintaining strict food safety practices, including proper storage and monitoring of food at safe temperatures to prevent potential outbreaks.
