Secretary for Culture, Sports and Tourism Kevin Yeung on Monday said the authorities will consider reopening the mammals section of the Zoological and Botanical Gardens when a health scare involving monkeys there comes to an end.

A De Brazza’s monkey, three common squirrel monkeys, four white-faced sakis and three cotton-top tamarins have died in the past week or so, with tests on some of them revealing they had melioidosis, an infectious disease caused by a type of bacteria in soil.

Officials said workers had dug up the ground near the monkey enclosure earlier this month and may have brought in contaminated soil on their shoes.

On a radio programme, Yeung said one monkey is still undergoing quarantine.

"When the situation is back to normal, we'll consider reopening the area. We've observed their behaviour and sometimes it was a little unusual compared to normal," he said.

"The condition of the monkey in quarantine fluctuates. Sometimes it is bad and sometimes it is good. It's receiving medical treatment."
