Foodborne IllnessQuestion 5 of 240
Within the temperature danger zone, bacteria multiply fastest in a narrower band. According to NYC course material, which range allows the most rapid bacterial growth?
a.70°F to 125°F
b.32°F to 41°F
c.140°F to 165°F
d.0°F to 32°F
Explanation
While the danger zone spans 41°F to 140°F in NYC, bacteria reproduce most rapidly between about 70°F and 125°F, where a single cell can double roughly every 20 minutes. Below 41°F growth slows sharply, and at 140°F or above most bacteria stop growing or die. Keeping TCS food out of the 70°F to 125°F band during cooling and holding is critical.
