Who can break regulatory seals on an HTST system?

The correct answer indicates that only authorized personnel are permitted to break regulatory seals on an HTST (High-Temperature Short-Time) pasteurization system for necessary repairs. This is important because regulatory seals are there to maintain the integrity of the pasteurization process and ensure that safety and quality standards are met.

Authorized personnel are typically trained and knowledgeable about the requirements and protocols surrounding the safe operation and maintenance of the system. By limiting the ability to break seals to this group, it helps prevent unauthorized access and ensures that only those who understand the implications and risks involved may perform actions that might compromise the system's integrity.

The other choices would not provide this level of controlled access. For instance, allowing anyone on the production team or limiting this power to a single individual like the quality assurance manager or plant manager could lead to operational risks. It's essential for maintaining compliance with health regulations that only specific, qualified individuals handle such critical functions, which is why the correct answer focuses on those who are thoroughly trained and authorized for this task.
