The blaze at the former Burry's Biscuits warehouse in Elizabeth broke out last Wednesday, spewing black smoke that could be seen for miles.
The fire was contained over the weekend, but safety concerns about the building's stability have kept firefighters from fully attacking the fire.
Fire personnel say a demolition company could be on the scene as early as Tuesday to assess the best way to penetrate the building and put out the remaining fire.
On Monday, a faint trail of white smoke could be seen coming out of the top of the building. The windows along the front and side of the massive structure were gone and revealed a blackened interior.
Authorities aren't sure what sparked the blaze, though it's believed that it started with a car fire inside a body shop in the warehouse.
No injuries have been reported.
