Hot and cold holding for the SmartSense probe

The SmartSense Probe offers temperature readings between -4 4°F (-20°C) and 212°F (100 °C). When using the probe for hot or cold holding, it’s important for the reading to stabilize to ensure the temperature measurement is accurate.  

In the United States, most foods are in a safe threshold when the temperature measurement is above 135˚F (57˚C) for hot food items and below 41˚F (5˚C) for cold food items. When food items are within a safe threshold, this helps prevent bacteria growth, a critical part of preventing foodborne illnesses.

Before using the SmartSense probe, ensure it is cleaned and sanitized. Follow the standard practices for probe usage. You can learn more about this here.

Hot Holding

Hot holding (in most states) requires hot holding food items to remain above 135˚F (57˚C) to prevent disease-causing bacteria. In some cases, disease-causing bacteria die at 135˚F.  

If bacteria are dying off at these temperatures, it can make sense that the sensors don't last.  Due to these high temperatures, a probe is recommended for monitoring hot holding units.

Use the probe frequently (every 2-4 hours or as instructed by a manager) to ensure food does not need to be reheated or discarded.  

Food examples include:

• Rotisserie chicken in a warming unit
• Hot rice stored in a rice cooker
• Self-serve, ready-to-eat hot foods in a warming unit (hot dogs, pizza, breakfast sandwiches)

Cold Holding

Cold holding (in most states) requires the cold holding food items to remain below 41˚F (5˚C) to stop or slow the growth of disease-causing bacteria. Colder temperatures lead to longer shelf lives and better product quality.

Food examples include:

• Cold cuts in a deli case
• Shredded lettuce in a cold tray salad bar
• Dairy items such as yogurt and milk
• Raw meats and poultry
• Ready-to-eat items such as pre-made sandwiches, parfaits, fruit tarts, salads, etc.

Use the probe frequently (every 2-4 hours or as instructed by a manager) to ensure food does not need to be rechilled or discarded.

Note: Ensure the SmartSense Probe is accurately measuring temperatures by calibrating the probe, if necessary. You can learn more about this process here.
