The Bangkok Metropolitan Administration (BMA) will raid unauthorised pet markets throughout the city following Tuesday's fire at a pet market in Chatuchak district which killed more than 5,000 animals.
Governor Chadchart Sittipunt said Sri Somrat Market, located behind the JJ Mall shopping centre, caught fire at 4.08am and was extinguished at 4.37am.
At least 5,300 animals, including many exotic species, which were kept in 118 pet shops in an area covering 1,400 square metres, were reported to have died.
Sri Somrat Market has been running a pet business for at least two decades. The market's operating licence was renewed four years ago, Mr Chadchart said.
Mr Chadchart said the BMA would investigate other pet markets to see their business ventures and animal welfare conditions.
The governor said that, from now on, every pet shop is required to have two permits, one from the BMA and the other from the Department of Livestock Development.
