Shipping fresh produce presents one of the most challenging logistics problems in the supply chain industry. When you need to transport fruits and vegetables from farm to market, how do you ensure they arrive fresh and safe? With tight shelf lives, strict temperature requirements, and complex regulations, getting produce to its destination requires meticulous planning and expertise in transportation management.
The produce logistics landscape has evolved dramatically. In 1954, Swanson revolutionized the food industry by introducing frozen dinner kits. Initially, Swanson produced 5,000 TV dinners, expecting modest growth. Within a year, they had sold over 13 million TV dinners.
People were hungry for convenience, and the market listened by expanding their logistical operations with refrigeration technology. By 1959, American consumers spent over $2.7 billion annually on frozen foods. None of this would have been possible without a logistical shift in more reefer and refrigerated truck technology.
Today, times have changed again. Fresh fruits and vegetables are making a comeback due to several factors:
- More health-conscious consumers
- A global pandemic affecting every industry
- Higher obesity and heart disease levels
Many consumers are opting for organic, locally grown produce, and if you're shipping produce, you need to master several food and beverage logistics capabilities in an already precarious process. With the advent of HelloFresh and other meal delivery services, fresh produce has become "in" again.
When shipping produce, you must meticulously plan shipping routes and consider:
- Weather patterns
- FMSA regulations
- Proper packaging
- Produce origin and seasonality
- Truck temperatures
- Shelf life
In this blog post, we'll cover how shipping produce works and the many steps and requirements you have to consider to transport produce from farm to market.
Produce Shelf Life
When you ship produce across the country or internationally, you're racing against a strict clock called shelf life. The shelf life of produce determines how long fruits or vegetables stay fresh and this varies due to a variety of factors. One of these factors is food density. This term should not be confused with 'nutrient-dense foods' or anything related to nutrition or weight. The shipping industry classifies certain foods as high, medium, or light density based on their shelf life.
High-Density Foods
High-density foods have a shelf life of about seven days and are the most reliable for long-distance travel. Potatoes, Carrots, and Onions fall under this category, likely because they have tougher skin. Apples, Cabbages, Celery, and Garlic, are also high-density produce.
Medium-Density Foods
Medium-density foods have a shelf-life of 2-4 days and typically require colder temperatures when transported. Think of fruits like oranges, peaches, watermelons, or vegetables like broccoli, tomatoes, and spinach.
Light-Density Foods
Light-density foods have a shelf-life of 1-2 days, making these foods the most critical for refrigeration and quick delivery. These types of foods are excellent candidates to be locally sourced. Strawberries, grapes, cucumbers, and green beans are considered light-density foods.
Shelf life not only affects taste but also affects its appearance. As anyone who shops for produce can tell you, ugly vegetables fall to the bottom of the pile.
For this reason, you must work closely with truckers to ensure punctual deliveries along the way. Clear communication between you and your trucker can be the difference between a truckload of fresh produce or a million-dollar mistake.
Truck Temperatures
In the cold chain logistics world, not all cold temperature is created equal. With perishable foods, exact temperatures matter. Different produce requires a specific temperature range. Even a change of one or two degrees can potentially spoil produce. Reefer containers are ideal for moving produce because their temperatures can be manually adjusted to stay within a target range during transportation. Reefer containers also have multiple temperature zones to transport various produce types simultaneously.
You should take care to include the temperature on the Bill of Lading so the destination can coordinate with their trucker to have a dedicated trailer ready.
The following ranges highlight how different products require specific temperatures.
- 32-36℉ - apples, strawberries, salad greens, grapes
- 38-40℉ - avocados, cranberries
- 40-45℉ - green beans, honeydews, potatoes
- 45-50℉ - cucumbers, eggplants, lemons, watermelons, grapefruit from FL or TX
- 55-60℉ - young potatoes, bananas, tomatoes, grapefruits from AZ or CA
Another factor to consider is the outside temperature. If routes pass through states or countries with extreme weather, this may impact the reefer trailer's temperature. Sometimes, a truck may need to drive through winter weather and adjust the trailer temperature, so the range is warm enough. These instances have to be taken into account when traveling cross country or overseas.
FMSA Regulations
In 2011, President Obama signed the Food Modernization and Safety Act to regulate and set safety standards in handling all foodstuff. The Act took a stance to proactively prevent foodborne illness and diseases by laying down sanitary standards for transporting and handling produce. Among these standards, four major components arose.
Clean Vehicles
All vehicles handling produce must be thoroughly washed and sanitized before and after deliveries to prevent contamination of any kind.
Controlled Temperature
Drivers must acknowledge temperature requirements for their shipment and report the temperature before, during, and after delivery. They must manually adjust the temperature as needed to make sure the produce does not spoil and must report any irregularities or temperature shifts.
Compliance Documents
Specific documents must be provided to drivers before delivery and kept for recordkeeping purposes. These documents cover:
- Vehicle cleanliness
- The trailer's temperature
- Sanitation records
- Procedure records
You should look for FMSA-certified trucking companies that understand every required standard. Your truckers should also regularly communicate with you to provide updates and any stalls along the way.
Seasonality and Produce Origin
Seasonality is a significant component of produce logistics unless you live in California, where most fruits and vegetables grow all year. If that's not the case, you have to consider what season yields which fruits and vegetables. For example, Wisconsin produces cranberries from mid-September to mid-October. New Jersey's cranberry season lasts through mid-November.
When your client's final destination is on the East Coast, how do you decide where to source? It makes more sense to source your cranberries from New Jersey. Change the destination to the Midwest, and Wisconsin would be a better option.
Produce origin is also a critical factor regarding shelf life. Tighter shelf lives mean suppliers should be as close to the final destination as possible. If you have the option of sourcing strawberries from a local farm 4 hours away from the final destination versus a full day's trip, chances are you'd source your strawberries from the farm instead.
Produce origin is also another factor consumers consider when shopping. More and more buyers—especially in grocery retail—are looking for locally grown, organic vegetables. Sourcing your supplies from local farms can leverage your competitive edge with buyers.
Final Thoughts
This article is just the beginning of understanding produce logistics. With more consumers demanding fresh fruits and vegetables as part of their daily diet, produce logistics is at an all-time high. When you need expert guidance on shipping perishable goods, partnering with experienced supply chain solutions providers can help ensure your produce arrives fresh and on time.
