In what phase do bacteria adjust after being introduced to new food?

The lag phase is the correct answer because this is the stage where bacteria adapt to their new environment after being introduced to a new food source. During this phase, they do not immediately start reproducing. Instead, they are busy adjusting to the conditions of the new environment, which includes metabolizing nutrients and repairing any damage. The duration of the lag phase can vary based on factors like the type of bacteria, temperature, and the characteristics of the food itself.

As the bacteria acclimatize, they prepare for the subsequent log phase, where they begin exponential growth. Understanding the lag phase is crucial in food safety, as it highlights the importance of ensuring that food is maintained at safe temperatures to minimize the risk of bacteria multiplying.
