Michigan Food Safety Management Practice Test

Which statement is true about the conditions of bacterial growth?

1. The Danger Zone is a range where bacteria do not grow

2. Pathogenic bacteria grow best in dry conditions

3. Pathogenic bacteria multiply roughly every 10-20 minutes under the right conditions

4. Most bacteria thrive at temperatures below 32°

The correct answer is: Pathogenic bacteria multiply roughly every 10-20 minutes under the right conditions

The statement regarding pathogenic bacteria multiplying roughly every 10-20 minutes under the right conditions is accurate. Bacteria thrive in warm temperatures, specifically when the environment is conducive, meaning it has the right moisture, nutrients, and suitable pH levels. The rapid multiplication rate allows pathogens to increase their numbers significantly in a short period, contributing to foodborne illnesses if food is not handled properly. This understanding is critical for food safety management because it emphasizes the importance of controlling conditions that promote bacterial growth, especially within the Danger Zone, which typically spans from 41°F to 135°F. This range is where bacteria can multiply rapidly. Thus, maintaining food outside these temperatures significantly reduces the risk of bacterial growth and contamination.
