SINGAPORE - The National Environment Agency (NEA) is investigating the sighting of a rat at Junction 8's foodcourt.

"We will take the necessary enforcement actions against any parties found responsible for rat infestation, or creating conditions favourable for harbourage or proliferation of rats," NEA said on Wednesday (Sept 21), adding that it takes a serious view of the incident.

A rat was filmed roaming near a teppanyaki food stall at Food Junction in the Bishan mall on Saturday (Sept 17) evening.

The video, posted by website Mothership.sg, showed three diners having their meal at a teppanyaki counter while the rat crawled in front of the counter, unseen by them.

Junction 8 has stepped up pest control measures, its marketing communications manager Edith Lim said.

It is working with the foodcourt to prevent such lapses, she said.

"We are working closely with the foodcourt to prevent a repeat of such incidents, and have also reminded our other F&B tenants of the cleanliness guidelines and stepped up our checks on them," Ms Lim said.

She added that the mall has instituted tenant guidelines on "proper housekeeping and pest control".

NEA has conducted more than 70,000 inspections on food shops and supermarkets in the first half of 2016, according to its website.

It also audits the rat control measures at shopping malls.

"As of June 2016, NEA has taken more than 100 enforcement actions against errant premises owners," it said.
