How E. coli got into Calgary daycare meat may never be known: Alberta Health Services report

A report into a massive E. coli outbreak at Calgary child-care facilities that saw hundreds fall ill says it was likely tied to meat loaf at one meal.

A report into a massive E. coli outbreak at Calgary child-care facilities that saw hundreds fall ill says it was likely tied to meat loaf at one meal, but how it got there can’t be determined for sure.

The report released Monday by Alberta Health Services says it’s not possible to say if the bacteria came from a contaminated ingredient in the meat loaf or into the meat loaf from elsewhere on the menu or through an infected kitchen worker.

The E. coli outbreak, declared on Sept. 4, 2023, led to at least 448 infections.

There were 38 children and one adult hospitalized for severe illness.

Of the severe cases, 23 were diagnosed with hemolytic uremic syndrome, a condition that damages blood vessels and kidneys and can lead to life-threatening kidney failure.

Eight received peritoneal dialysis, which is done to remove waste products from the blood when the kidneys are failing.

Another 33 secondary cases have also been linked, including household contacts and children in other daycare facilities.

There were no deaths.
