The number of minutes remaining in the poultry's temperature zone is; 3 hours and 45 minutes
<h3>How to find the temperature zone?</h3>
We are told that On the counter is poultry that has been left at a temperature of 17.5 °C for 15 minutes.
Converting 17.5°C into Fahrenheit equals 63.5 °F. This temperature in degrees Fahrenheit is within the danger zone. Now, hot food can be held in the danger zone for 4 hours. Due to the fact that the food has been on the counter for 15 minutes already, it means that it can be held on the counter for another 3 hours and 45 minutes before it becomes unsafe.
