After processing, pasteurized milk should be cooled to refrigeration temperatures within a short time frame per plant SOPs. Which option best captures this guidance?

• A. To room temperature for a long time.
• B. To refrigeration temperatures within a short time frame per plant SOPs.
• C. To freezing temperatures.
• D. To body temperature.

Answer: (B)

Cooling pasteurized milk promptly to refrigeration temperatures is essential because pasteurization reduces pathogens, but warmth can let any surviving microbes multiply and degrade quality. The goal is to reach cold storage temperatures quickly, within the specific timeframe outlined by the plant’s SOPs, to minimize growth and protect safety and quality. Reaching refrigeration temperatures (typically around 4°C or lower) slows microbial growth and helps maintain product integrity during storage and distribution. Letting milk sit at room temperature would allow rapid bacterial growth, while freezing is not the standard immediate post-pasteurization step for routinely processed milk. Bringing milk to body temperature would create an unsafe window for microbial growth.
