New EU study on the epidemiology of non-typhoidal salmonella

A recently published, EU-funded multinational study led by the Netherlands confirms that non-typhoidal salmonellae remain among the most common zoonotic pathogens in the EU and the United Kingdom. Most human infections are caused by the serovars Salmonella Enteritidis and Salmonella Typhimurium. The study comparably analyzed the five most common Salmonella serovars in Europe using core-genome multilocus sequence typing and machine learning methods.

The results show that pets do not contribute significantly to the spread of the serovars studied. It also shows that salmonella infections in humans often occur in countries other than those from which the raw materials or food originate. This is attributed to the close international interconnection of European food chains.

Further information on salmonellosis is provided by the Robert Koch Institute, among others.
The BAV Institute offers specialized tests for salmonellae, even with large sample sizes, and supports companies with product safety issues.
