Building a mixed reefer load or filling a cold room? Add commodities — including meat, dairy & seafood — and this checks what spoils a shared load: temperature conflicts, ethylene producer-vs-sensitive clashes, odor transfer, and chilling-injury risk — then suggests the safe setpoint. For common produce it uses USDA's official Load Compatibility Groups; for flowers, nuts and exotics (not in those groups) it falls back to the storage data. Sources: USDA AH-66 + Transport by Truck.
Never set a reefer below a commodity's band — most fresh produce is damaged by freezing, and chilling-sensitive items are injured well above 0 °C. Group loads within one band.
