Final answer:
Milk can be safely received at 45 degrees Fahrenheit if it has been subjected to UHT pasteurization, which sterilizes the milk and allows for long-term storage without refrigeration.
Step-by-step explanation:
Milk can be received at 45 degrees Fahrenheit (7 degrees Celsius) provided it has undergone a process such as ultra-high-temperature (UHT) pasteurization, where milk is heated to 138 °C for 2 or more seconds. After this treatment, milk can be stored for long periods without refrigeration, as it effectively sterilizes the milk, allowing it to remain stable even at higher temperatures than typically recommended for milk storage. This method is especially useful in areas with limited access to refrigeration. However, if milk has not been treated with the UHT method, it should be stored at temperatures just above freezing to prevent rapid spoilage and to maintain food safety standards, as bacteria can quickly grow at warmer temperatures.
