Butter, cheese and biscuit dough were just some of the items lost in a Snowy Mountains truck fire in the early hours of this morning.
Emergency services were called about 2.40am to the Hume Highway, just north of the Snowy Mountains Highway intersection, at Mount Adrah.
A refrigerated Coles Supermarket b-double trailer, with mixed freight, was alight.
A Fire and Rescue NSW spokesperson said reports suggest that cooking oil was alight and leaking diesel fueled the fire.
"Thankfully, the driver was unharmed," the spokesperson said.
"Police said they could hear popping noises but they didn't know what was inside and kept distance, while waiting for us to arrive.
"We were on scene about 3.11am."
According to Live Traffic NSW, the truck fire closed the highway northbound, with traffic being diverted via the Snowy Mountains Highway, Gocup Road, Eagle and Cross streets.
One of two northbound lanes was reopened about 11.30am.
The FRNSW spokesperson said about four crews accompanied two Rural Fire Service teams on scene.
"The main trailer was detached ... with generic food, hazardous vegetable oil and butter inside," they said.
"Crews recovered 8000 litres of liquid."
A Riverina Police District Facebook post noted that the fire was extinguished about 4.50am.
