Sanitizing is a critical process in food safety that aims to significantly reduce the number of microorganisms on surfaces to safe levels. The correct answer highlights the dual methods that can be utilized in sanitizing: heat and chemicals.

Using heat to sanitize typically involves applying high temperatures, such as through steam or boiling water, which can effectively kill or deactivate pathogens. This method is often employed in dishwashing and cooking processes, where the heat interacts with various types of microorganisms, ensuring they are destroyed or rendered inactive.

On the other hand, chemical sanitizers, such as chlorine, iodine, or quaternary ammonium compounds, are highly effective in disinfecting surfaces and utensils. These chemicals work by disrupting the cellular processes of microorganisms, leading to their elimination.

Both methods are valid and can be applied depending on the scenario and the type of surface being sanitized. For example, heat may be more suitable for surfaces that can withstand high temperatures, while chemicals might be more practical and efficient for surfaces that may be damaged by heat.

Overall, understanding that both heat and chemicals can play a role in the sanitizing process is essential for maintaining food safety standards and preventing foodborne illness.
