Final answer:
Taco Bell's temperature range for safe cold and hot ingredients should follow the guidelines for food safety. Cold ingredients should be stored below 4 degrees Celsius or 40 degrees Fahrenheit to inhibit bacterial growth, while hot ingredients should be cooked above 60 degrees Celsius or 140 degrees Fahrenheit to kill bacteria.
Step-by-step explanation:
Taco Bell's temperature range for safe cold and hot ingredients should follow the guidelines for food safety. The safe temperature range for cold ingredients is generally below 4 degrees Celsius or 40 degrees Fahrenheit, which inhibits bacterial growth in refrigerated foods.
On the other hand, the safe temperature range for hot ingredients is typically above 60 degrees Celsius or 140 degrees Fahrenheit, which helps kill bacteria during cooking.
