How quickly can bacteria double in number under optimal conditions?

Under optimal conditions, certain types of bacteria can double their numbers in as little as 15-20 minutes. This rapid reproduction is primarily due to the ideal environment that supports their growth, including optimal temperature, pH levels, and availability of nutrients. In the case of pathogens, this can lead to a significant increase in their population, potentially resulting in foodborne illnesses if food is not handled or stored properly. The ability to rapidly multiply is one of the reasons why it is crucial to practice good food safety techniques, such as maintaining proper refrigeration and cooking temperatures, to inhibit bacterial growth and ensure food safety.
