DELANCO, N.J. — A massive fire that severely damaged a southern New Jersey food warehouse continued to burn Monday morning, nearly 24 hours after it broke out.

Dozens of firefighters were battling the 11-alarm blaze at the Dietz and Watson distribution plant in Delanco. Officials said about 50 percent of the fire had been contained, but their efforts were being hampered by water supply issues and the threat of electrocution due to the thousands of solar panels on the building's roof,

The fire started around 1:30 p.m. Sunday. It sent plumes of thick, black smoke billowing from the building and caused the roof to collapse a short time later.

No injuries were reported. The only people on the campus at the time were two security guards who manned a station outside the building.
