Highlights, posted February 1, 2024


Public Health investigated an outbreak of salmonellosis (caused by Salmonella bacteria) associated with IHOP in Bellevue. The people who became sick reported eating a wide variety of breakfast foods at IHOP.


Three people from three separate households reported becoming sick. The people who became sick ranged in age from 20 to 70 years old. All three people developed one or more symptoms consistent with salmonellosis, including nausea, vomiting, abdominal cramps, diarrhea, bloody stool, and fever. We did not identify any ill employees.

Public Health actions

Public Health conducted interviews with the people who became sick to identify potential common exposures and identified that they all became sick after eating at IHOP in Bellevue. No specific food was identified.

Environmental Health Investigators requested source information and food receipts from the restaurants on January 11, 2024. Investigators visited the restaurant on January 16, 2024. Investigators reviewed the restaurant’s food preparation processes and did not identify factors that may have contributed to the outbreak. The facility conducted a thorough deep cleaning and reinforced food safety training with staff.

Laboratory testing

All three cases had testing that identified Salmonella infections via culture. Further testing found all three cases had the same strain of Salmonella based on genetic fingerprinting (whole genome sequencing or WGS) at the Washington State Public Health Laboratory.
