Outbreaks picThe European Centre for Disease Prevention and Control (ECDC) has issued an epidemiological update on a multinational outbreak of Salmonella Enteritidis infection that has affected junior ice-hockey players attending an event in Latvia.

The Finnish health authorities first reported an outbreak of salmonellosis among players attending the Riga Cup in April. Around 5,000 players from 19 countries attended the tournament from 27 March to 26 April. As of 22 May 42 teams have reported 187 cases from six different countries (Estonia, Finland, Lithuania, Norway, Sweden and the UK).

The outbreak strain of Salmonella Enteritidis has been characterised as Phage type 1 with a rare MLVA (Multiple-Locus Variable-Number Tandem Repeat Analysis) profile.

The teams affected stayed at four different hotels in Riga, but all ate organised meals at the four arenas where the tournament matches took place. A common source of exposure has not yet been identified, and microbiological tests by the Latvian health authorities have yielded negative results, but ECDC considers this to be a point source outbreak.

A preliminary investigation report has been published in the journal Eurosurveillance and can be found here.
