Who developed the method of pasteurisation to prevent spoilage of food by bacteria?

Appeared in: AIIMS Manglagiri NO - 2019

Explanation

Louis Pasteur developed the method of pasteurization, a process named after him.
Pasteurization involves heating liquids like milk and wine to a specific temperature for a set duration to kill harmful microorganisms such as bacteria, viruses, and molds.
This process is crucial for food safety as it prevents the transmission of foodborne illnesses and extends the shelf life of products without significantly altering their nutritional value or taste.

Option A: Edward Jenner's primary contribution was in the field of immunology, not food preservation. He is celebrated for developing the world's first vaccine, which was for smallpox.
Option C: Joseph Lister is known as the 'father of antiseptic surgery'. His work focused on preventing infections in surgical wounds by using chemical disinfectants like carbolic acid, not on preserving food.
Option D: Robert Koch was a founder of modern bacteriology who identified the specific bacteria causing diseases like tuberculosis, cholera, and anthrax. He established Koch's postulates to prove a specific microbe causes a specific disease.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Key Figures in the History of Microbiology as background academic context rather than a clinical decision trigger.
Pasteurization is a fundamental public health measure that prevents the transmission of diseases like tuberculosis, brucellosis, and listeriosis through contaminated milk and other food products.
The principles of microbial destruction by heat, established by Pasteur, are the foundation for modern sterilization techniques (e.g., autoclaving) used in hospitals to prevent healthcare-associated infections (HAIs).
Nurses educate patients and communities about the importance of consuming pasteurized dairy products to prevent infectious diseases.

How to Approach the Question

First, identify the key term in the question, which is 'pasteurisation'.
Recognize that the term 'pasteurisation' is an eponym, meaning it is named after a person.
Scan the options to find the name that closely matches the key term. 'Pasteur' in 'Louis Pasteur' directly corresponds to 'pasteurisation'.
Select this option as the most probable answer.
Briefly recall the contributions of the other scientists to confirm they are not related to this process (Jenner = vaccine, Lister = antiseptic, Koch = postulates/germ theory).
