What is the meaning of thermal sanitization in sanitation methods?

Thermal sanitization refers to the process of using steam or heat to eliminate microorganisms and pathogens from surfaces or objects. This method is effective because high temperatures can destroy harmful bacteria, viruses, and other pathogens, ensuring that items are safe for use. It is often used in settings where hygiene is critical, such as in food processing, healthcare, and equipment sanitization.

In contrast, other options do not fit the definition of thermal sanitization. Using chemical agents pertains to chemical sanitization, which involves applying disinfectants to clean surfaces. Washing hands frequently relates to personal hygiene practices rather than a specific sanitization method using heat. Implementing filtration systems is more aligned with removing contaminants from water or air rather than using heat as a means of sanitation. Thus, the focus on heat in the correct answer underscores the specific technique involved in thermal sanitization.
