What is a noted limitation of boiling water sterilization?

Boiling water sterilization is commonly used for disinfecting items but has some limitations in effectiveness, particularly concerning certain types of microorganisms. One notable limitation is that to be effective, boiling water must be maintained at the appropriate temperature for a sufficient duration, generally considered to be at least 10 minutes. This duration ensures that most pathogens are killed; however, it does not guarantee complete sterilization.

While boiling water is effective against many bacteria and viruses, it does not reliably kill bacterial spores, which are much more resistant to heat. Therefore, relying solely on boiling water for the sterilization of all surgical instruments is not advisable, as it may not ensure the destruction of all forms of microorganisms that could pose a risk in a surgical setting.

Furthermore, practical considerations must also be noted—boiling water may not be suitable for all surgical instruments, particularly those that may be damaged by high heat or those that require special sterilization processes. Thus, the time required for boiling is critical in assessing its limitations alongside the effectiveness against spores and its applicability across all types of instruments.
