In April 2026, public health officials in Ontario, Canada investigated an outbreak of Salmonella Enteritidis infections among patrons of Piper Arms restaurant located in Stoney Creek, Ontario. A total of 86 cases were identified. Twenty-nine cases were laboratory confirmed. Nine people were hospitalized.

Evidence from Hamilton Public Health's Food Safety investigation and epidemiological analysis of cases suggests cross-contamination contributed to transmission within the restaurant rather than a sole food item as the source of illnesses.

The officials reported that they found Salmonella in cheese and that they thought it had cross-contaminated other food, utensils and food contact surfaces
