A food worker at a catered event finds grilled shrimp that have been held at room temperature for the last four hours. What should she do with the shrimp?
Discard them
Cool them to 41’F (5°C) within two hours
Reheat them to 175°F(79°C) before serving to additional customers

The correct answer and explanation is :

The correct answer is: Discard them.

When handling food, particularly seafood, it is critical to follow food safety guidelines to prevent foodborne illness. Shrimp, like other perishable foods, should not be left at room temperature for extended periods because harmful bacteria can multiply rapidly within a few hours. According to food safety standards, foods that have been held at room temperature for more than two hours should be discarded to avoid the risk of contamination.

Why Discarding is the Best Option:

1. Temperature Danger Zone: The temperature danger zone for food is between 41°F (5°C) and 135°F (57°C), where bacteria grow most rapidly. Holding shrimp at room temperature (which is typically higher than 41°F or 5°C) for four hours places them firmly in this danger zone, allowing bacteria to multiply to potentially harmful levels. Even reheating shrimp to 175°F (79°C) will not ensure that any toxins produced by bacteria are eliminated, making the shrimp unsafe to eat.
2. Bacterial Growth: Shrimp and other seafood are particularly susceptible to bacterial contamination. Bacteria such as Vibrio, Salmonella, and Listeria can proliferate quickly when food is left out at improper temperatures. These pathogens can cause severe foodborne illnesses, especially in vulnerable populations such as the elderly, children, pregnant women, and individuals with weakened immune systems.
3. Food Safety Regulations: According to the U.S. Food and Drug Administration (FDA) and food safety guidelines, perishable foods should not be kept at room temperature for more than two hours. When foods are left out for longer than this, they should be discarded to avoid any risk of foodborne illness outbreaks.

Alternative Solutions for Safe Food Handling:

• If food cannot be served immediately, it should be refrigerated at 41°F (5°C) or lower to slow bacterial growth.
• If the shrimp were in a warm environment (above 90°F or 32°C), they should not be left out for more than one hour.

In this case, since the shrimp were held at room temperature for four hours, the safest course of action is to discard them to ensure the health and safety of those consuming the food.
