Several cases of gastroenteritis have been potentially linked to a stall at the Enlighten Night Noodle Markets in Canberra.

ACT Health issued a statement, saying several people reported becoming ill with diarrhoea about 10 to 13 hours after eating food from a stall at the festival.

"Environmental Health Officers have today inspected the premises that supplies the food for this stall," the ACT Health statement said.

"Potentially hazardous food found out of temperature control has been disposed of and the stall will not be able to sell the implicated food for the remainder of the festival."

A spokeswoman was not able to name the stall.

She said the stall was still in operation at the festival and the potentially hazardous food had been removed.

ACT Health said there was no longer any risk to public and the outbreak was now controlled.

An Events ACT spokeswoman said the organisation acted immediately after being made aware of the food poisoning cases.

"The issue was reported to Fairfax Events, who worked with ACT Health Protection Service to quickly identify any food safety issues and act accordingly," she said.

"A full assessment of the vendor site was conducted, with the site being deemed safe for service."

The popular market event has run each night since last Friday at Reconciliation Place in Canberra's south, in association with the Canberra Times Good Food Month.

ACT Health said anyone who suspected they had food poisoning should avoid school and work for 48 hours after diarrhoea or vomiting ceases, and see their doctor if the symptoms lasted longer than a few day.
