Final answer:
A bag of fresh broccoli should be stored on the cooler, middle shelf to maintain freshness and prevent frost damage. Refrigeration slows bacterial growth but does not kill bacteria completely.
Step-by-step explanation:
The correct location for storing a bag of fresh broccoli would be in the cooler. The best practice would be to place it on the cooler, middle shelf, as fresh produce generally should be kept in a cool environment, but not so cold that it could be damaged or succumb to frost. The middle shelf of a refrigerator is usually at a consistent temperature, thus protecting the broccoli from temperature fluctuations that can occur closer to the top or bottom of the refrigerator or in the door shelves.
It is important to note that while refrigeration can slow the growth of bacteria, it does not completely kill bacteria. Therefore, it is also essential to maintain proper food safety practices, such as washing the broccoli before use and keeping it separate from raw meats to prevent cross-contamination.
