Identify the temperature danger zone for bacterial growth, which is between 4\(\degree\) C and 60\(\degree\) C. This range is where bacteria can multiply rapidly and potentially cause foodborne illness.
Examine each food item's temperature and compare it to the danger zone: Milk at 2\(\degree\) C, Potato salad at 25\(\degree\) C, Chicken soup at 65\(\degree\) C, and Frozen shrimp at -18\(\degree\) C.
Determine if the temperature of each food falls within the danger zone: 2\(\degree\) C is below 4\(\degree\) C, so milk is outside the danger zone; 25\(\degree\) C is within 4\(\degree\) C to 60\(\degree\) C, so potato salad is inside the danger zone; 65\(\degree\) C is above 60\(\degree\) C, so chicken soup is outside the danger zone; -18\(\degree\) C is well below 4\(\degree\) C, so frozen shrimp is outside the danger zone.
Conclude that the food item at a temperature that allows bacteria to grow well is the one held at 25\(\degree\) C, which is the potato salad on the buffet table.
Understand that keeping food either below 4\(\degree\) C or above 60\(\degree\) C helps prevent bacterial growth and reduces the risk of foodborne illness.
