Which bacteria is known for its ability to grow under refrigeration temperatures?

Yersinia is noteworthy for its ability to thrive at refrigeration temperatures, making it one of the few pathogens that can grow in these cooler environments. This characteristic is particularly concerning in food safety, as it means that typical storage methods intended to inhibit microbial growth may not effectively control this bacterium.

Yersinia enterocolitica, for instance, can be found in a variety of food sources, especially in undercooked pork and contaminated water. Understanding the growth temperature range of this bacterium is vital for food service operators to ensure proper food handling and storage practices. When food is improperly stored or left in the danger zone of temperature, Yersinia could multiply, posing a risk of foodborne illness to consumers.

The other bacteria listed have different growth requirements. For example, Escherichia coli typically requires warmer temperatures to thrive, while Salmonella and Campylobacter are also more active at temperatures above refrigeration levels. This highlights the importance of recognizing the characteristics of specific pathogens to maintain food safety effectively.
