Watsonville, California, US: Investigators say they do not suspect arson was the cause of the fire at the Apple Growers Ice and Cold Store warehouse that caused around $10m (£6m) worth of damage.
The blaze lasted for several days and caused damage to the building and contents, mainly apples, sparkling cider and apple juice.
S Martinelli and Company was one of many companies that used the warehouse.
Fire crews brought in a tanker to offload ammonia that was kept outside the warehouse.
Investigators say there were eight to 10 potential ignition sources. They were looking at roofing work done on an attached shed just before the fire started, and at the electrical system and an evaporator that was part of the cooling system.
