A pharma cold-storage tour and a food cold-storage tour look almost identical for the first ten minutes. Same insulated envelope, same racking, same dock doors, same hi-vis vests, same forklift trucks. By minute twenty the difference is obvious. The setpoint discipline, the SOP density, the audit posture, and the people running the room are not the same operation.
We run both at the Colden Mehsana facility. The room holds a GDP-validated pharma vault inside the same envelope as the food cold-storage operation. Two separate quality systems. Two separate SOP libraries. Two separate teams. Same operating model, very different operating discipline.
Here is what is actually different.
Setpoint discipline
Food cold storage runs to a window. Frozen food is "at or below -18 degrees C." Setpoints drift inside that window during defrost cycles and dock-door events. A 2 degree swing during a defrost is normal. A 90-minute door cycle that drifts the front of the room by a degree is fine.
Pharma cold storage runs to a setpoint, not a window. Frozen vault is -18 degrees C, plus or minus 1 degree. Defrost cycles are sequenced to avoid the temperature signature drifting outside the window. Door events are minimised by design. A pharma vault dock-door cycle that takes 8 minutes is a written incident.
If your food cold-storage team has never been inside a pharma vault, they will be surprised by how quietly the room runs.
SOP density
Food cold-storage operations might run on 40 SOPs covering receiving, putaway, picking, slotting, cycle counting, cycle counting variance, cycle counting reconciliation, and so on. BRCGS audits sample against those SOPs.
Pharma cold storage on a GDP standard runs on something closer to 140 SOPs. Every move has an SOP. Every alarm has an SOP. Every alarm response has an SOP. The deviation log has an SOP. The deviation log review has an SOP. The deviation log review escalation has an SOP. Customer audits sample exhaustively against the SOP library, and the operator has to be able to produce the SOP, the SOP revision history, and the training record per operator per SOP.
If your operations team has been trained on BRCGS, they will need additional training before they can work the pharma side.
Audit posture
Food cold-storage audits are scheduled. BRCGS runs annually. Customer audits come with notice. FSSAI inspectors are on-site for licence inspections but their scope is documented.
Pharma cold-storage audits arrive at any time. Customer quality teams audit on their own schedule, sometimes with two weeks notice, sometimes with two days. Regulatory audits (CDSCO, EMA inspections for export programmes) arrive without notice. The vault has to be audit-ready every shift, not audit-ready every quarter.
This is the change of posture that catches food operators when they move into pharma. Cleaning is not "before the audit." Cleaning is the schedule that lets the room pass an audit on any given day.
People
Pharma cold-storage operators are not failed food operators. They are a separate discipline. We hire pharma operators with quality system experience, train them on the GDP SOP library, and assign them only to the vault. Food operators do not rotate into the vault. Vault operators do not rotate to the food side. This is partly a quality control issue and partly a training-cost issue. Cross-training is expensive, and the cost of an excursion in the vault is too high to absorb that risk.
What this means for customers
If you are a pharma customer scoping cold-storage, the right questions are not about square footage or pallet positions. They are about the SOP library size, the deviation log frequency over the last 12 months, the customer audit pass rate, and the staff turnover in the pharma team. A vault with high turnover is a vault that will have an excursion. A vault with a thin SOP library will fail your next audit.
If you are a food customer scoping cold-storage, the operations questions still matter. BRCGS certificate, FSSAI licence, cycle count accuracy, dock-to-rack time, and debit note history. The operating model has to fit your category. Asking pharma-grade questions of a food operator is not going to help anybody.
A practical observation
The biggest mistake we see in this conversation is treating pharma cold storage as "food cold storage, but stricter." It is not. It is a different sport with overlapping rules. Operators who do not understand that build their pharma vault with the wrong people, the wrong SOPs, and the wrong reporting cadence, and they fail their first real customer audit.
We built the Mehsana vault as a separate operation from day one, with its own ops manager, its own quality lead, and its own training programme. The decision pays for itself every quarter.
