Step 1: Understanding the Concept: Pasteurization is a controlled heat treatment process designed to destroy pathogenic microorganisms in certain foods and beverages like milk.
The classic Holder method involves heating milk to \(63^\circ\text{C}\) (\(145^\circ\text{F}\)) for 30 minutes.
Step 2: Key Formula or Approach: The approach requires identifying the thermal death point characteristics and heat resistance of various milk-borne pathogens.
Step 3: Detailed Explanation: Historically, pasteurization temperatures were designed primarily to kill Mycobacterium tuberculosis and Brucella abortus.
However, it was later discovered that Coxiella burnetii, the causative agent of Q fever, is significantly more heat-resistant and is the most heat-resistant non-spore-forming pathogen found in milk.
It is uniquely capable of surviving the classic Holder method of pasteurization.
To ensure the complete destruction of C. burnetii, pasteurization standards were revised worldwide, and higher temperatures (such as High-Temperature Short-Time, HTST, at \(72^\circ\text{C}\) for 15 seconds) are now commonly used.
Step 4: Final Answer: Coxiella burnetii is known to survive the traditional Holder pasteurization method.
