Final answer:
The option that is not a principle of food protection from bacterias is d. Promote the locomotion of bacteria. The three principles are killing bacteria, preventing bacterial growth, and stopping the spread of bacteria.
Step-by-step explanation:
In response to the question, d. Promote the locomotion of bacteria is not one of the three principles of food protection from bacteria. The three main principles to protect food from bacterial contamination are to:
Kill bacteria, through methods such as cooking or pasteurization.
Stop bacteria from growing, by refrigerating or freezing food, and controlling the moisture and pH levels.
Keep bacteria from spreading, by using proper hygiene and sanitation practices, such as washing hands and using clean utensils and surfaces.
Promoting the locomotion of bacteria would be counterproductive, as it may lead to further spreading of pathogens rather than their control. In contrast, proper food handling and preparation methods are essential to avoid foodborne illnesses and ensure the safety of food consumed.
