What is in-process sampling and when is it used?

• A. Sampling after packaging
• B. No sampling
• C. Sampling during production to assess quality/safety at a CCP or process step; used to detect deviations early
• D. Sampling before production begins

Answer: (C)

In-process sampling means taking samples while the product is being made, at a point in the production steps where control can influence safety or quality. This approach provides real-time information about how the process is performing and whether the product meets preset criteria as it is formed. It is used to assess quality and safety at a critical control point or at a specific process step, so deviations can be detected early and corrective actions can be taken before the batch is finished. This helps keep the process within established limits, supports timely decisions about batch release, and strengthens overall product safety.

For context, this differs from sampling after packaging, which looks at the finished product only, and sampling before production, which doesn’t monitor how the process behaves as it runs. Some plans may also involve no sampling, but in-process sampling is specifically about active monitoring during production to catch issues early.
