10 Blind Spots in Cold Chain Risk Management You Might Not Know You Have

Most shippers, by this point, tend to believe they have visibility into their cold chain. What “visibility” truly covers, though, is often little more than surface-level location data.

The gap between knowing where a shipment is and knowing what happened to it along the way is where cold chain programs can come across some of their costliest failures, whether the cargo is a pallet of insulin or a truckload of frozen shrimp. The industries built around temperature-sensitive freight don’t talk to each other much.

Pharmaceutical logistics teams are managing global, multimodal shipments that can pass through dozens of handlers under enforceable federal regulation. Food and beverage teams are managing largely regional freight where a bad outcome typically results in spoilage on a relatively small scale.

The various types of cold-chain operations have their differences, but ultimately the failures are similar: unconnected data, alerts that arrive too late or too often to act on, and incidents that occur due to a combination of security and quality control lapses.

We asked specialists at Overhaul (which works across temperature control and cargo security applications in life sciences, food and beverage) to walk through where cold chain programs are exposed without realizing it. Often, it’s the assumptions you take for granted that can cause some of the most devastating issues. 1. Location isn’t the same as condition.

The most common cold chain “visibility” tool is a GPS ping, but location alone is insufficient, particularly when it comes to temperature-sensitive loads. “GPS tells you where a truck is. It does not tell you whether the product inside still meets the temperature spec,” said Todd Thompson, Director of Enterprise Sales at Overhaul.

Thompson works with food and beverage shippers and says that capturing, reporting, and reacting to ambient temperature, product temperatures, shock, and humidity allows for corrective actions to be applied while a shipment is still recoverable. A map pin doesn’t do that. 2. The custody record is unhelpful when it’s scattered.

Most companies aren’t missing chain-of-custody data, but they’re lacking a single place to find it. “Companies are compliant in capturing the data,” Thompson said. “The responsibility to provide this data is understood, but the problem is that the data is scattered in disparate systems and in different formats, therefore delaying responsiveness,” he said.

Pharmaceutical shipments compound the problem. A single drug delivery to a pharmacy can involve roughly 50 different handlers across the supply chain, according to Melita Marks, Cold Chain Market Advisor at Overhaul. 3. More alerts can lead to poorer visibility through fatigue.

Modern sensors can unfortunately generate a lot of noise, and pharma logistics teams are often leaner than they used to be. “They’re getting disjointed information, with too many alerts,” Marks said. That pushes decisions from proactive to reactive. Left unaddressed, that fatigue becomes its own risk.

“Pharma companies need smarter systems to pinpoint what to pay attention to,” Marks said, pointing to risk-scoring, shipment triage, and condition data with live events as the fix rather than simply adding more alerts. 4. Passing at the dock doesn’t mean nothing happened.

A shipment can drift out of range repeatedly in transit and still read clean on arrival because the product temperatures recovered before the receiving process started. Without the adequate temperature history combined with location information, it may be almost impossible to track down when and where a lapse occurred, if you’re even aware at all.

“On frozen, a partial thaw and refreeze on a case of fries does not fail at the dock, it fails in the fryer,” Thompson said. The temperature abuse can surface long after the fact as a shortened shelf life or a store/restaurant claim further down the supply chain. 5. Disruption response is a speed problem, not a lead-time problem.

Large, forecastable events like hurricanes give shippers time to plan around them. The harder cases are the sudden ones, as in a reefer failure or an unplanned closure. In those types of instances, the question isn’t whether to reroute, but how much product is still usable.

“In mature cold chain programs, there have been responses, corrective action decisions, and rerouting if needed, that have happened in minutes,” Thompson said. “More typically you are looking at a few hours from alert to action based on product category,” he said.

The constraint, he noted, is rarely the event itself, but instead in how fast and complete the condition data reaches the people who can act on it. 6. Entering a regulated lane is a financial decision before it’s a compliance one. Carriers who might be eyeing an expansion from general reefer freight into pharma often underestimate what it costs to get there.

Reefer trailers need to be temperature-mapped empty and loaded against seasonal extremes, and warehouses need
