A food worker checks the temperature of hot-held sautéed mushrooms.
Which temperature would be cause for concern?
a. 131°F (55°C)
b. 136°F (58°C)
c. 142°F (61°C)
d. 145°F (63°C)
The Correct Answer and Explanation is:
The correct answer is:
a. 131°F (55°C)
Explanation:
In food safety, maintaining appropriate temperatures for hot-held foods is critical to prevent the growth of harmful bacteria that can lead to foodborne illnesses. The recommended minimum hot-holding temperature for most cooked foods, including sautéed mushrooms, is 135°F (57°C). This temperature is set by the U.S. Food and Drug Administration (FDA) and other health agencies to limit the risk of bacterial growth in prepared foods that are kept out for serving or further use.
Why 131°F (55°C) is Concerning:
If sautéed mushrooms are held at 131°F, they are below the safe hot-holding temperature threshold of 135°F. When the temperature of hot-held food drops below 135°F, it enters the “temperature danger zone” (typically defined as 41°F to 135°F or 5°C to 57°C), where bacteria such as Salmonella, Staphylococcus aureus, and Clostridium perfringens can multiply rapidly. Bacterial growth in this temperature range doubles roughly every 20 minutes, increasing the potential for contamination and foodborne illness, especially if the food remains at an unsafe temperature for prolonged periods.
Other Temperatures in the Choices:
- 136°F (58°C), 142°F (61°C), and 145°F (63°C) are all above the safe minimum hot-holding temperature of 135°F and, therefore, would not be a cause for concern. These temperatures indicate that the sautéed mushrooms are safely above the threshold where bacterial growth slows significantly or halts, helping to ensure food safety.
Importance of Monitoring and Immediate Action:
Food workers must monitor temperatures frequently, especially in a buffet or food service setting, to ensure foods are consistently held at safe temperatures. If food is found to be below 135°F, corrective actions—such as reheating the food to the proper temperature or discarding it—must be taken to maintain food safety and protect consumers from the risk of illness.
In summary, holding sautéed mushrooms at 131°F would be cause for concern due to the increased risk of bacterial growth at this temperature.
