Plumes of black smoke crossing Barossa Valley Way at Nuriootpa on Tuesday afternoon was the result of a rubbish burn off which had reignited.
Just before 3.30pm on November 5, the fire alarm was raised with two CFS appliances and police attending a property at Nuraip Road.
Barossa Police said the fire was the result of a reignited rubbish burn off, near a home, which was contained within the property.
"The only area affected was dry grass and some scrap metal/old car bodies in the year," a Barossa police spokesperson said.
The original rubbish burn off was held on a non fire ban/non fire season day, with police saying no offences reported.
A CFS media spokesperson added how "fire bombers were directed to the grass fire", however due to the nature of the blaze and firefighters response, a stop call was made.
Meanwhile, Barossa Police say those conducting burn-off or rubbish burning on non-fire ban days need to ensure the fire and all embers are fully extinguished using water and ensure there is a clear fire break around the burn off.
"We have now had a number of reignites across the area and they pose a significant risk because the reignition is unpredictable," the spokesperson said.
