Final answer:
Fresh fish should last three to five days when properly refrigerated at or below 4 degrees C (40 degrees F). Other items like eggs and beef roasts can last longer, while ground pork has a similar shelf life to fresh fish. Proper refrigeration and cooking to the right temperature are key to food safety.
Step-by-step explanation:
When properly refrigerated at or below 4 degrees C (40 degrees F), fresh fish is the food item that typically lasts between three to five days. Perishable foods like fresh fish should be stored correctly to prevent the growth of harmful bacteria. It's important to note that other foods mentioned like eggs, a beef roast, and ground pork generally have different refrigeration longevity. Eggs can last considerably longer, while a beef roast can last a bit longer than fresh fish when refrigerated. Ground pork should also be stored under refrigeration and consumed within a similar timeframe to fresh fish, depending on storage practices and whether the pork is raw or cooked.
Regularly monitoring the refrigerator's temperature can help ensure foods are stored safely. Additionally, meats such as ground beef and chicken should always be cooked to a 'well done' state to ensure that they are safe to eat, reaching an internal temperature of at least 74 degrees C (165 degrees F) to kill any bacteria present.
