How much prior notice should IPP give before collecting a sample?

• A. No more than 24 hours
• B. No more than 1 week
• C. Long enough to allow them to hold product, but not long enough to alter their processes
• D. Long enough to allow them to alter their production schedule, but not long enough to ship the product

Answer: (C)

Providing prior notice should strike a balance between isolating the sample and not giving the facility time to modify what they’re doing. The best approach is to notify enough to hold the specific product lot so the IPP can collect a representative sample, but not so much time that the facility could alter their production processes in anticipation of sampling. This preserves the sample’s integrity and ensures the inspection reflects normal operations. Giving too little time may hinder proper hold and sampling; too much time could allow changes that bias the results.
