A Salmonella outbreak at an IHOP restaurant in Bellevue, Washington, has health officials puzzled. The outbreak, which began in October 2023, has affected six individuals to date, with two requiring hospitalization. Fortunately, no deaths have been reported.
Salmonella is a bacterium that can cause severe gastrointestinal illness in humans. Symptoms typically include diarrhea, fever, and stomach cramps, appearing six hours to six days after exposure to the bacteria. While most people recover without specific treatment, the infection can be severe, especially for young children, the elderly, and individuals with weakened immune systems.
The King County Public Health Department has been actively investigating the situation since January 2024, when they were notified of the initial cases. The outbreak has proven challenging to contain, with new cases emerging even after multiple closures and deep cleaning efforts at the restaurant.
The affected individuals, ranging in age from 16 to 70, reported consuming various breakfast items at the IHOP located across Lake Washington in a suburb of Seattle. All experienced common Salmonella symptoms, including nausea, vomiting, abdominal cramps, diarrhea, and fever.
Public Health officials have taken several actions to address the outbreak. These include conducting environmental sampling, ordering multiple temporary closures of the restaurant, and mandating thorough cleaning and disinfection procedures. Despite these efforts, the outbreak has persisted, with the most recent case linked to a meal consumed on June 8, 2024, just one day after the restaurant had reopened following an extensive cleaning.
The investigation has faced challenges in identifying a specific food source responsible for the outbreak. Environmental samples taken from the restaurant in April 2024 tested positive for the outbreak strain of Salmonella, indicating potential ongoing contamination issues within the facility. However, samples taken on June 28, 2024, following the reported June 8 illness, were negative for the pathogen. The agency said that Salmonella may yet still exist within the restaurant. In response to the latest incident, IHOP was again required to perform a deep cleaning and disinfection and was allowed to reopen a week later.
Commenting on this article, one national Salmonella lawyer said, “These incidents show the importance of stringent food safety practices in restaurants as Salmonella can cause severe illness, especially in vulnerable populations. Although eliminating persistent bacterial contaminations can be challenging, it is nevertheless mandatory to ensure the health of the public.”
King County’s Public Health Department is closely monitoring the situation and has required the IHOP to maintain heightened cleaning and food safety protocols. They have urged the public to report any suspected foodborne illnesses promptly.
The investigation remains open and the agency said it will continue to provide updates as the probe into the source of the food poisonings progresses.
