Why would you ask an auditee this question rather than reviewing the records before the audit and then talking to the supervisor if there were a concern? I'm with Golfman25 on this one.
For example, if I pull a finished product that's sitting on a truck and about to be released for delivery, I'd grab all the tag info and then follow it all the way back to when the raw materials that went into that product were received. Or trace it back as much as possible - the people who worked on that product might not be working that day, but I can talk to their counterparts that are working, find out what they know and how they know it, look at their records, etc. I can also pull any QC data relevant to that final product originally grabbed...and make sure that processes are in place to show that it was okay and released for shipment accordingly. And so on.
Without knowing who you're going to be speaking with, there may be little alignment or context between the records and the people you're speaking (depends on the organization - if they operate 24 hours a day with rotating shifts, the records looked at might not be for those currently on shift).
