Let's Talk Logistics

Shipping temperature-controlled freight can be a risky business even on the best of days, but when outside temperatures soar to record-breaking highs, (most recently putting 13 million Americans under a severe heat advisory), it is time to pay extra attention to your cold freight shipments.

The past month was the hottest June in North America on record. In recent days, California, Nevada, and Arizona all surpassed previous record temperatures. It has been so hot in the Pacific Northwest that roads are actually buckling. What does this mean for shippers and carriers?

Every produce shipping season is different, but 2021 has more than one extenuating circumstance that could make it one for the record books. Not only are we coming off of a volatile, high volume post-pandemic freight market, but we still are trying to recover after a week of bizarre winter weather in Texas and the deep South that devastated many winter crops.   

Melons, onions, lettuce, and broccoli were just some of the more than $600 million in damaged produce. According to Texas A&M Today, the estimated losses from weather-related storms are broken down by these categories:

• Citrus crops, at least $230 million
• Livestock, at least $228 million
• Vegetable crops, at least $150 million

Speculation about how much shipping costs will increase this year vary, but industry experts agree that rate hikes are inevitable, and soon.

The last year has tested the industry to its limits. Expecting the unexpected has become the norm because of COVID-19. It has stretched us like too little butter over too much bread, creating far-reaching consequences. Now that the pandemic threat may be winding down in many places, we are presented with one more thing to make us grind our teeth at night—more cost to our bottom line.

Tracking & Real-Time Visibility

Less than a decade ago, a shipment of frozen fish would leave a dock in California and possibly go through several different states and several different temperature zones before arriving at its destination. It also may have had several deliveries along the way. The shipper knew it was frozen when it left its place of origin, and the receiver made a notation that it was frozen upon arrival at its destination. But what about the four hours it sat in an open truck while other cargo was being unloaded on a hot 102°F day in the Southwest? Before GPS tracking and real-time visibility, there was no way of knowing what happened in between points A, B, C, and D.

Packaging, Palletizing, Staging and Pre-cooling

It may sound simple, but shipping refrigerated cargo successfully starts with proper packaging, palletizing, and loading of the product. Many claims relating to spoiled or damaged temperature-controlled cargo begin with poorly executed pre-loading procedures. 

These topics and others will be the focus of our upcoming webinar, "Refrigerated Shipping: Myths versus Facts." In the meantime, read on to learn some of the most important things shippers can do to keep their perishable freight safe.  

What’s the big deal about pulping?

Taking temperatures isn’t just something you should do for COVID-19. It is an essential part of shipping produce on refrigerated trucks. In the logistics industry the process is called pulping, and it is the act of taking the fruit’s or vegetable’s temperature during various stages of the shipment.

If God had written ten commandments for shipping produce, the first commandment would be, “Thou shalt not put a warm load of melons straight from the field into a pre-cooled truck and expect it to deliver on-temp.” Every cold chain shipper should know this.

Ready to hear some crazy statistics about America's food in the supply chain? Before I divulge any numbers, let's look at the big picture concerning the food we ship in this country.

The food we grow in the United States combined with the food we import is more than enough to sustain the population amply. That's the good news. The bad news is there are still more than 37 million starving people in the U.S., reports Feeding America—but the real kicker? Of all the food waste in this country, up to 40 percent occurs in the supply chain, according to the USDA's website. Do we have any control over this astronomical percentage? Well, let's just say we can do better.

It all started in a small underground bunker in Antarctica, with a French scientist, his two colleagues, and a glass of whiskey. After a long day of drilling through ice, a few ice chips from a core sample were precisely what his glass of amber-colored liquid needed. While staring at his drink, the ice emitted several bubbles that floated to the surface. It dawned on the scientist that the air (specifically the CO²) trapped in the bubbles if analyzed, might be able to tell a story.

When temperatures reach 98 – 100 degrees with heat indexes as high as 115, like last weekend in Maryland, everything cold gets warm incredibly fast! During these extreme temperatures, many shippers are requesting that even fresh loads run at 26 degrees instead of 28.
