Temperature control is the single most important variable in frozen meat logistics. Once the chain breaks — even briefly — bacterial growth resumes, ice crystals damage muscle fibres, and product quality degrades irreversibly.
The cold-chain timeline
A typical export shipment moves through five stages, each with its own temperature risk:
- Blast freezing — product is frozen to -18 °C (or below) within hours of slaughter and cutting.
- Cold storage — maintained at -18 °C at the packing plant until shipment.
- Inland transport — refrigerated trucks move containers from plant to port.
- Port staging — the container waits at the terminal, plugged into shore power.
- Ocean transit — reefer containers maintain set-point temperature for 20–45 days depending on route.
Where breaks happen
The two highest-risk moments are:
- Loading dock transfers — when product moves between cold storage and the truck or container. Dock seals and rapid loading minimize warm-air ingress.
- Port power gaps — if a container is unplugged between inland delivery and vessel loading. Reputable ports maintain uninterrupted reefer power.
What importers should ask
- What is the blast-freeze protocol? (Target core temperature and time)
- Are temperature data loggers included in every container?
- What is the port plug-in SLA?
- Can you provide a temperature chart for the full transit?
Reefer container specs
Standard 40' high-cube reefers hold roughly 26–28 tonnes of frozen meat. They maintain set-point accuracy to ±0.5 °C and record temperature at intervals throughout the voyage. The data log is available to the receiver upon arrival.
Choosing an exporter with vertically integrated logistics — from their own cold stores to port — reduces the number of handoffs and the risk of temperature excursions.
