Answer:
Leftover potato salad that has been out for four hours during a hot day should be thrown away, as it has been at an unsafe temperature and could harbor harmful bacteria, making it unsafe to eat. The correct option is (c).
Explanation:
The correct action to take with the leftover potato salad that has been sitting out for four hours on a hot sunny day is to throw away the leftovers because they have been at an unsafe temperature for too long. Foods meant to be eaten cold should be kept refrigerated until served to prevent the growth of harmful bacteria.
Perishable leftovers that have been left at a temperature between 4 and 60 degrees Celsius (40 and 140 degrees Fahrenheit) for more than two hours are considered unsafe and should be discarded to prevent the risk of foodborne illnesses.
Even though the salad might not show visible signs of spoilage or have a spoiled smell, it has been at an unsafe temperature which could promote the growth of pathogens such as Clostridium botulinum, which cannot be detected through smell or appearance and can produce a deadly neurotoxin. Therefore, the only safe and professional recommendation is to dispose of the potato salad to ensure no one risks getting sick from consuming it.
According to food safety guidelines, perishable leftovers that have been left at a temperature between 4 and 60 degrees Celsius (40 and 140 degrees Fahrenheit) for more than two hours should be thrown away. Since the potato salad has been sitting out for 4 hours on a hot sunny day, it is no longer safe to consume.
