Final answer:
In a cooler, the beef roast should be stored at the bottom, followed by halibut, lettuce, and then ground chicken, to ensure proper storage and prevent cross-contamination.
Step-by-step explanation:
In a cooler, food should be stored in the top to bottom order based on their required cooking temperatures.
- Since beef roast is a type of meat that requires a higher cooking temperature, it should be stored on the bottom of the cooler.
- Next, halibut should be stored in the cooler as it requires a lower cooking temperature than the beef roast.
- Then, lettuce can be stored in the cooler, as it does not require cooking.
- Lastly, the ground chicken should be stored on the top of the cooler as it is more susceptible to cross-contamination.
