AHS investigating gastrointestinal illness outbreak at Calgary restaurant

CALGARY – Alberta Health Services (AHS) is investigating a gastrointestinal illness outbreak associated with Kinjo Sushi & Grill-Mahogany, located at #200, 7 Mahogany Plaza SE, Calgary, AB. 

Currently, there are four confirmed cases and two probable cases associated with the outbreak. All confirmed and probable cases reported eating food at the facility on or around Sept. 18, 2026. Based on current testing, the pathogen associated with the outbreak has been identified as Shiga toxin-producing Escherichia coli (STEC). Individuals who consumed food or beverages at the facility on or around Sept. 18 and 19 may have been exposed to STEC. 

What is STEC?

STEC is a type of bacteria that spreads when someone comes into contact with food or water contaminated by fecal matter. Person to person transmission may also occur when someone does not wash their hands after using the washroom. It often causes nausea, vomiting and diarrhea with stomach cramps and generally goes away without treatment. Dehydration, caused by diarrhea, is the most common complication. More information about STEC can be found on MyHealthAlberta.

What to do if you have STEC symptoms:

• If you have symptoms, call 811 or your primary care provider for medical assessment. A stool test may be ordered by your provider to check for STEC. Immunocompromised individuals should consider early medical assessment.
• Hydration is important for people with symptoms of gastrointestinal illness. You can find further information on caring for people with these symptoms on MyHealthAlberta.

To prevent spread of infection, we recommend the following:

• Frequently wash your hands with warm, soapy water, including after you go to the washroom, before you prepare food, after you touch raw meat, after changing diapers, and before you eat.
• Thoroughly wash all kitchen tools and surfaces before and after meal preparation.
• Do not share food, drink, or eating utensils with someone experiencing symptoms.
• Individuals who are unwell should stay home from work or school.
• If you have diarrhea, please do not enter any swimming pool, water spray park or other aquatic facility for at least two weeks after symptoms resolve.
• To help prevent the spread of infection, individuals with symptoms should limit close contact with people at higher risk of severe illness, including young children, older adults, and or immunocompromised individuals.

Public health officials are working to identify the source of the infection, assess any ongoing risk and prevent additional illnesses. A public health inspection conducted on Sept. 28, 2026, found no critical violations at the facility. There are no other reported cases of STEC linked to this facility at this time. The restaurant remains open while the investigation continues.

Anyone with questions or concerns can contact Health Link to speak to a registered nurse 24 hours a day, seven days a week, by dialing 811.
