What is the main reason TCS foods must be held at safe refrigeration temperatures?

TCS (Temperature Controlled for Safety) foods require proper refrigeration to inhibit the growth of pathogenic bacteria, which can pose serious health risks if ingested. When TCS foods are not stored at safe refrigeration temperatures, they become conducive environments for bacteria to multiply rapidly, increasing the likelihood of foodborne illnesses. This risk is particularly relevant because some pathogens, such as Salmonella, E. coli, or Listeria, can thrive in these foods if they are kept in the temperature danger zone (between 41°F and 135°F).

While factors like preserving taste, preventing spoilage, and ensuring texture quality are important for the overall quality of food, the primary and critical reason for maintaining safe refrigeration temperatures is to inhibit the growth of harmful bacteria that can cause illness. Therefore, understanding proper refrigeration practices is essential for food safety in any food service operation.
