What is it about?
Salmonella infections are often acquired through ingestion of contaminated food of animal origin and contact with infected animals or contaminated environments. Previous studies have identified some risk factors of paediatric salmonellosis due to different lifestyle, dietary habits and environmental condition at different geographical regions. Recognition of the principal source of transmission of Salmonella infection in children is important for public health advocacy to reduce salmonellosis burden.

Why is it important?
Our study show that consumption of food purchased from places other than a supermarket was the identified determinant factor for non-typhoidal Salmonella gastroenteritis in Hong Kong. Parents/caregivers should be alerted to this risk when choosing foods for their young children. The protective effect of playing in an indoor playroom could be confounded by socioeconomic factors and further investigation is required to better understand its potential implication. There was some support for person-to-person transmission and good family hygiene needs to be emphasised.
Perspectives
I hope the outcomes of this research can benefits our community especially children who are vulnerable to infectious diseases.
