Fresh produce is one of the most demanding freight categories. Temperature, timing, palletization, and carrier selection all affect whether your product arrives in sellable condition. Here's the full playbook.

What It Means
Fresh produce transportation is a specialized category of temperature-controlled freight that demands precision at every step — from pre-cooling the trailer to specifying the correct temperature set point to managing transit time against the product's remaining shelf life. Unlike non-perishable freight, produce that arrives outside temperature specification or beyond the optimal delivery window may be unsaleable.
Canada's produce market relies on an extensive reefer carrier network moving fresh fruits, vegetables, and herbs from growing regions in BC, Ontario, and Quebec, as well as US imports through Windsor-Detroit, Fort Erie-Buffalo, and other border crossings. Harvest season — August through October — creates peak demand for reefer capacity that shippers who don't plan ahead pay for at peak rates.
Why It Matters
- Produce has near-zero tolerance for temperature deviation — a few degrees too warm accelerates ripening and decay rapidly
- Shelf life at delivery directly determines your buyer's ability to sell the product before spoilage
- Harvest season creates competitive reefer capacity demand — shippers who plan ahead secure equipment and rates; those who don't face premium spot pricing
- Carrier selection for produce goes beyond price — carriers must understand pre-cooling, airflow, and temperature monitoring
- Border crossing delays for cross-border produce imports can push transit time beyond product tolerance if not anticipated
How It Works
Temperature Requirements by Commodity
- Leafy greens and berries: 0°C to +2°C
- Stone fruit (peaches, cherries, plums): 0°C to +5°C
- Root vegetables (carrots, beets, turnips): 0°C to +5°C
- Apples and pears: -1°C to +4°C
- Citrus (oranges, lemons, grapefruit): +3°C to +8°C
- Tomatoes (ripe): +10°C to +13°C
- Tropical fruits (bananas, mangoes): +12°C to +15°C
Pre-Cooling
The trailer must be pre-cooled to the specified set point before loading begins. This is non-negotiable. A refrigeration unit is designed to maintain temperature in a pre-cooled trailer — not to rapidly cool a warm load during transit. Failure to pre-cool is the single most preventable cause of produce temperature damage.
Palletization and Airflow
Cold air from the refrigeration unit flows from the front of the trailer through floor channels and around the load. Pallets must be loaded to maintain these airflow channels. Blocking the channels — whether by tight palletization, floor-level product, or inconsistent pallet heights — creates warm spots that cause localized spoilage even when the overall trailer temperature reads correctly.
Temperature Logging and Documentation
Temperature loggers provide continuous temperature records throughout transit. For produce, these records are essential documentation for quality disputes at delivery. Many grocery retailers and distributors now require temperature records at receiving as a condition of acceptance.
Common Challenges
- Trailers not pre-cooled to set point at time of loading — most preventable failure
- Incorrect temperature specification — confirm commodity requirements with your QA team, not from memory
- Airflow restrictions from improper palletization creating warm spots in the load
- Border crossing delays extending transit time beyond produce tolerance for cross-border shipments
- Harvest season capacity shortages — shippers who don't book in advance face availability and rate problems simultaneously
Best Practices
- Know your commodity's exact temperature requirement — confirm with your QA team before specifying to the carrier
- Specify the pre-cool requirement explicitly when booking — write it into the booking confirmation
- Use temperature loggers on every produce load, particularly for high-value or long-transit moves
- During harvest season (August-October), book reefer capacity at least 48–72 hours in advance
- Communicate transit time requirements clearly — not just the delivery date, but the hours-of-transit tolerance
- Understand remaining shelf life at pickup and ensure transit time is within acceptable limits
- Review POD temperature logs at delivery and flag any deviation before signing off
When to Use This Service

Frequently Asked Questions
What is the most common cause of fresh produce loss during transportation?
The most common causes are temperature deviations (trailer not pre-cooled or incorrect set point specified), extended transit times that exceed the product's remaining shelf life, improper palletization that restricts airflow and creates warm spots, and border crossing delays for cross-border produce shipments.
How far in advance should I book reefer capacity during harvest season?
During BC, Ontario, and Quebec harvest seasons (August–October), book reefer capacity at least 48–72 hours in advance, and preferably further ahead for dedicated lanes or high-volume periods. Spot market reefer capacity during peak harvest commands significant rate premiums and is not always available.
Do I need a temperature logger on every produce load?
For high-value produce, long-transit moves, and any shipment where a quality dispute is possible, temperature logging is strongly recommended. Loggers provide the documentation needed to support or defend quality claims at delivery. Many grocery retailers and distributors now require temperature records at receiving as a condition of acceptance.
What happens if produce arrives outside temperature specification?
Produce arriving outside specification may be rejected, accepted with an allowance (price discount), or accepted subject to quality inspection. Temperature logs documenting a deviation during transit are essential to determine whether the carrier is responsible. Without logs, resolving the dispute is difficult and typically falls to the shipper.
