Waterloo health officials are asking you to monitor for symptoms if you visited Algarve Restaurant between October 28 and November 4.
According to a press release, the location is linked to six positive COVID-19 cases so far.
Officials estimate that up to 175 people could have been exposed to the disease while visiting the restaurant.
Potential exposed guests
The food venue has voluntarily closed its doors as officials investigate.
"As a precaution, Public Health is advising anyone who attended during these times to monitor themselves for symptoms for 14 days after their last visit and to seek testing," wrote public health.
However, officials believe that this outbreak did not originate from the food joint.
Rather, it is believed that the cases first spread through a social gathering and was then brought to the restaurant.
If you have visited the location outside of the exposed dates, there is no risk of contracting COVID-19.
