The bug that caused a group of Leicester City Council health inspectors to fall ill after a night out at a popular Indian restaurant was salmonella.
The Leicester Mercury reported that the council's food safety team took 49 samples from the kitchen at Kayal in Grandby Street, Leicester, after 19 people reported feeling unwell after eating there over a two-week period in November.
The restaurant, which has enjoyed a five-star score under the Food Hygiene Rating Scheme, closed pending the investigation.
It has since reopened.
The salmonella was present in only one sample, a chutney that is prepared fresh on the premises each day.
Owner Jaimon Thomas told the paper: "Because of the findings, we have stopped making fresh chutney in the way that we always have for the past eight years. Customer safety is our top priority.
"I want to thank all the customers who contacted me to give us support, and we are determined to restore our reputation."
