Services · Food & beverage
Produce, meat, dairy, frozen food, beverages and packaged food, plus pharmaceuticals and other cold chain freight. FSMA is one of my certifications: your load moves in clean, suitable equipment at the temperature you set, under the FDA’s Sanitary Transportation rule.

FSMA
The Food Safety Modernization Act’s Sanitary Transportation rule (21 CFR Part 1, Subpart O) covers how human and animal food moves by truck and rail. It requires vehicles and equipment that can be kept clean, temperature control where food safety depends on it, protection against contamination and cross-contact, trained carrier staff, and written procedures and records.
As the shipper, you tell the carrier in writing what the load needs: the temperature, pre-cooling, and any sanitary requirements such as prior-load restrictions. I make sure those instructions reach the truck and the driver.
Equipment
Temperature-sensitive food rides in a refrigerated trailer, shelf-stable food in a clean, food-grade dry van, and high-value cold chain freight with extra monitoring.

A clean, dry, odor-free van for shelf-stable food and beverages.
For high-value, temperature-sensitive freight: round-the-clock temperature monitoring and equipment tracking, thermal-mapped trailers, and quality processes built around pharmaceutical guidelines.

It’s an FDA rule under the Food Safety Modernization Act (21 CFR Part 1, Subpart O) that sets requirements for moving human and animal food by motor and rail vehicle: sanitary vehicles and equipment, temperature control, protection from contamination, carrier training and records.
You set it, based on the product. Frozen loads often run around 0°F or below and fresh chilled products in the mid-30s °F, but your set point and acceptable range go on the load instructions.
Yes. Shelf-stable food and beverages often move in clean, food-grade dry vans. Temperature-sensitive products need a refrigerated trailer.
Refrigeration units record temperatures during the trip, and the records can be requested when you need proof the load stayed in range. Tell me up front if you’ll need them.
Yes. Landstar’s cold chain service is built for temperature-sensitive, high-security freight such as pharmaceuticals, with 24-hour temperature monitoring and tracking, thermal-mapped equipment and quality processes that follow pharmaceutical guidelines. Tell me the temperature range and any validation or documentation requirements up front.
A washout is a cleaning of the trailer between loads. Some food shippers require a washout certificate before loading; let me know and I’ll book it.
FSMA requirements differ for shippers, loaders, carriers and receivers. This page is general information; your food safety plan decides what your loads need.
