Question: 1 / 400

How often can some bacteria double under optimal conditions?

Every 30 minutes

Every 60 minutes

Every 20 minutes

Some bacteria can double in number approximately every 20 minutes under optimal growth conditions, which include the right temperature, pH, and nutrient availability. This rapid duplication process is indicative of their ability to thrive in favorable environments, reflecting their efficiency in utilizing resources for growth.

The ability of bacteria to double so quickly is crucial in food safety because it highlights how quickly food can become unsafe if not handled or stored properly. For example, in the right conditions, one bacterium could multiply to over a million in just a few hours, potentially leading to foodborne illness if consumed.

Other time frames mentioned in the incorrect options, such as 10, 30, or 60 minutes, are not representative of the fastest common bacterial replication rates in optimal conditions, making 20 minutes the most accurate choice.
