Nationwide outbreak of Salmonella enterica serotype Kedougou infection in infants linked to infant formula milk, Spain, 2008

On 5 August 2008, the National Reference Laboratory of Salmonella (NRLS) noted an increase in the number of isolates of Salmonella enterica serotype Kedougou.

As of 22 August, 29 isolates have been reported during 2008, which is ten times more than the average number of isolates identified by the NRLS during 2002-2007. All isolates have a typical, indistinguishable Pulse Field pattern (SALKEDXB-1, Spanish code) and are fully sensitive to the standard suite of antimicrobials.

Of the 29 patients with S. Kedougou, 12 were male. Twenty three patients were younger than one year while the remaining six were aged between seven and 76 years. From the available information we know that one of the adult patients is the father of one infant infected with S. Kedougou.

In the context of this outbreak we defined a case as an infant younger than one year old with clinical symptoms compatible with a salmonella infection and an isolate of S. Kedougou from stools, blood or urine, since 1 January 2008. As of 22 August, 23 cases fulfilling the case-definition were identified with the onset of symptoms between 4 February and 28 July 2008 (Figure).
