Three samples in China's Tianjin municipality showed traces of the coronavirus, possibly due to a combination of poor hygiene and cold storage temperatures.
The fire broke out in an area used to store faulty batteries and other waste products, the company said.
The explosion comes days after two huge blasts in Tianjin killed at least 121 people.
Suspicions that official corruption contributed to the disaster have been bolstered by recent revelations about the warehouse owners.
WHAT'S HAPPENING
“There has to be a link between the dead fish and the blast. What else could explain the death of so many?”
At least 10 people have been taken into custody following the deadly explosions last week.
The company that owns the warehouse did not have a license to store dangerous chemicals for over a year.
Rain could create further toxic gas.
The chemical explosion left over 100 people dead.
