If you asked your team to trace an ingredient lot back to its source today, how long would it take? I would start answering that question by looking at the problems the operation already encounters. A wrong label or a damaged delivery can tell you something about how easily people can establish what arrived and follow its history. Then I would give the team a lot to trace, put a clock on the work and use what we learn to address gaps with our partners.

What to follow up
The supplier lot was found in 12 minutes. Ask the partner to demonstrate the still-unconfirmed connection from lot B-62 to its source.
Internal lookup took 35 of the 40 minutes. Review how the team found the delivery record and matched it to the supplier lot.
Getting partner information took 48 of the 60 minutes. Ask how that source link was retrieved and whether finding it was difficult.
Notice what ordinary problems reveal
If you are close enough to your team, you should have some sense of how they handle questions about the goods coming in. When something looks wrong, can they establish which batch arrived? Can they work backward to understand what happened? How difficult does that become?
These do not have to be major incidents. Take a delivery with the wrong label, or goods that arrive damaged. The immediate problem needs attention, but I would also pay attention to the work involved in following it back. The team’s experience of doing that is useful information for an operations leader.
If an ordinary question turns into a nightmare, I would take that seriously. A recall would put greater pressure on the same need to retrieve information. Struggling with a smaller problem gives us a reason to investigate before we face that pressure.
When the team says a delivery problem is resolved, I would ask how long it took to establish its history and whether retrieval was difficult. That helps show where a deliberate check would be useful.
Give the team a lot to trace, and time the exercise
A practical next step is to go to the person responsible for quality control, give them an ingredient lot and ask them to trace it all the way back. Put a clock on the exercise so we can see how long finding that information actually takes.
This gives us something concrete to discuss. We have asked the team to retrieve a particular lot’s history, and we can see whether they can do it within a time frame we consider acceptable. Having records available somewhere does not, by itself, answer that question. The exercise asks people to use them.
Research has also used timing to assess practical tracing performance. In their 2013 Journal of Food Science study, Tejas Bhatt and Jianrong (Janet) Zhang assessed tracing technologies through scenarios informed by industry data. They reported that “Time metrics were useful for evaluating the scalability and usability” of the technologies. Their work illustrates why elapsed time is useful alongside the ability to complete a trace; it does not establish a universal response time for our operation.
For our team, I would bring the discussion back to the exercise we have just done. Could we get all the way back? How long did it take? If finding the information was difficult, we now have something specific to follow up rather than a general feeling that tracing should work.
Depending on the ingredients and suppliers involved, it may make sense to repeat this once a month. The frequency needs to fit what we handle and who we depend on. I would consider a regular exercise because it gives us another opportunity to see how the team manages the task.
A successful backward trace gives us evidence about that part of our preparation. Other parts of a recall still need attention; this exercise does not establish that the entire response will work.
Bring the gaps into supplier and partner conversations
When the difficulty involves information from another business, the conversation needs to extend beyond our own team. I would go back to the relevant partner and explain the visibility we need. That might involve a supplier or another external business handling the goods. The point is to address the gap with whoever can help us follow the lot back.
That can become a serious commercial conversation. If we cannot get the information we need to trace our supply chain, we have to ask whether the relationship can provide it. If the gap cannot be addressed, we may need to work with a different partner. We do not want to discover that limitation when everyone is waiting for answers.
Reporting on FDA tabletop exercises in June 2026, Food Safety Magazine said that “proactive supply chain coordination drove the strongest results”. Those exercises examined readiness for the FDA’s traceability rule. The finding gives us a practical reason to look beyond the information held inside our own facility and ask what the businesses we depend on can retrieve.
I would also bring these questions into the conversation before taking on a new supplier. Ask how they would respond if we called about a particular ingredient lot from a delivery. How would they show us its history? What systems would they use to trace it back?
A specific lot question gives the supplier something concrete to explain. We can understand how they would handle our request and what they would be able to show us. That is useful to establish while we are deciding whether to work together, alongside learning from the difficulties we encounter with existing partners.
Start with what ordinary problems reveal, then give the team a lot and see how the backward trace works. Use the result to have a more informed conversation with the people and businesses involved. Confidence should grow from seeing the information retrieved and addressing the gaps that make it difficult.
