Every year, about 600 million people in the world get infected foodborne diseases and 420,000 people die each year due to these diseases.

This study was conducted to investigate a gastroenteritis outbreak in one military unit located in the northeast of Iran in May 2017. In order to determine the source of the disease, a line listing was prepared and completed by 296 staff of the unit. Then, the source of the outbreak was identified by calculating the relative risk for the meals consumed within 48 hours before the beginning of the outbreak and using the stratification method to adjust the confounding effect.

In this outbreak 323 people were infected. The disease attack rate was 22.4%. 51% of staff were infected. The most common symptoms of the disease were fever, diarrhea and headache, respectively. Only the relative risk of boiled eggs was significant and was identified as the source of the outbreak (RR = 2.4). The cause of the outbreak was Shigella and less likely Salmonella.

The long-time gap between the cooking of dinner and its distribution has been one of the underlying factors of the outbreak. It seems that the boiled eggs remain in the lukewarm water inside the pot for several hours before being distributed to the staff and the secondary contamination of the pot containing the eggs was the cause of this outbreak.

The publication of outbreak investigation reports is critical for disseminating lessons learned from outbreaks. While there are existing reporting guidelines for outbreak investigations, there is a gap in specific guidelines for reporting food-borne and water-borne outbreaks. This study aims to introduce a specific framework and reporting guideline for food and waterborne outbreak investigations in Iran.

The initial draft of the framework for reporting food and waterborne outbreaks was derived from existing general reporting guidelines for outbreak investigations. Additionally, a systematic review of studies reporting outbreaks of waterborne and foodborne diseases from 2010 to 2022 was conducted without language restrictions to extract relevant information. Expert opinions were then sought to finalize and adapt the reporting guideline.

The reporting guideline framework for outbreaks of waterborne and foodborne diseases consists of eight parts: title, abstract (background, methods, results, conclusion), introduction, methods (study characteristics, study type, variables under investigation), results (participant information, statistical results, laboratory results, environmental investigation results), discussion, conclusion, and conflict of interest.

This specific reporting guideline for food and waterborne outbreak investigations can be utilized by outbreak investigation teams, rapid response teams, and researchers to effectively report the results of outbreak investigations in this domain.
