Which method is used in sterilization to eliminate all disease-causing organisms?

• A. Pasteurization
• B. Sanitization
• C. Use of chemicals, heat, or pressure
• D. Cooling with refrigeration

Answer: (C)

The method that is used in sterilization to eliminate all disease-causing organisms is the use of chemicals, heat, or pressure. This approach encompasses a variety of techniques, such as autoclaving, which employs high-pressure steam to achieve temperatures that destroy all microbial life, including spores. Chemical sterilants can include substances like ethylene oxide or certain peracetic acid formulations, which are effective in killing a wide range of pathogens. In contrast, the other options do not fully achieve sterilization. Pasteurization, for example, is designed to reduce the number of viable pathogens in food and beverages but does not eliminate all microorganisms, hence it is not considered sterilization. Sanitization refers to reducing microbial contamination to safe levels but does not necessarily eliminate all pathogens. Cooling with refrigeration slows down the growth of microorganisms but does not kill them, so it cannot be classified as a sterilization method.
