What is unique about the bacteria Listeria?

Listeria is particularly noteworthy because it can grow at low temperatures, including those typically found in refrigerators. This ability allows it to thrive in environments where many other pathogenic bacteria may be inhibited or killed off. While most bacteria are unable to multiply at temperatures below 40°F (4°C), Listeria can still replicate, making it a significant concern for food safety, especially in ready-to-eat foods.

The fact that Listeria can grow at refrigerated temperatures is a crucial point for food safety management, as consumers often rely on refrigeration to prevent the growth of harmful microbes. Understanding this characteristic emphasizes the importance of proper food handling and regular monitoring of refrigerator temperatures to ensure food safety.
