Five European international locations have reported Salmonella infections with at least a couple of of them linked to tahini and halva from Syria.

Up to 80 of us could perchance presumably even have been affected since 2019 in Germany, Sweden, Norway, Denmark and the Netherlands with several forms of Salmonella being linked to the outbreak.

Primarily based fully on epidemiological recordsdata and entire genome sequencing (WGS) analyses, consultants from the Robert Koch Institut (RKI) in Germany urged Meals Security News that they give idea to circumstances with the Salmonella serovars Mbandaka, Havana, Amsterdam, and Orion to be share of the outbreak.

Germany has 51 sufferers, with 49 confirmed by WGS plus two with an epidemiological link to a WGS-confirmed case. This comprises 21 in 2019, 12 in 2020 and 18 in 2021.

RKI officers said they within the origin famed an amplify in Salmonella Havana case numbers in 2019 but were unable to title the source of an infection. These sufferers have been retrospectively linked to the unique outbreak primarily primarily based on WGS results. Whole genome sequencing provides so-called fingerprints of micro organism, figuring out fits between sufferers and particular pathogens.

Reported illness onset dates range from January 2019 to Would possibly 2021. There are a couple of imaginable of us in unlucky health with onset dates in June 2021, which could perchance presumably be no longer but WGS-confirmed. The age of circumstances ranges from 6 months to 69 years and 53 p.c are female. They live across Germany in 15 of 16 federal states.

Rob in Norway


Norway has two sufferers with Salmonella Mbandaka who reported drinking sesame seed merchandise. They’re 5 and 45 years extinct, every female and from varied regions of the country. Sampling dates of the isolates were March 2020 and June 2021.

Recalled merchandise in Norway

Sesame seed merchandise Al Burj Tahina and Al Burj Halwa from Syria and imported into Norway were recalled earlier this month. Absolute best sooner than dates range from June 2021 to January 2022.

The resolve on relies totally on detection of Salmonella in attempting out by Sweden and preliminary results from samples by Mattilsynet. Examinations are ongoing to gape if the recalled merchandise in Norway are rotten with Salmonella Mbandaka.

Sweden is investigating two clusters of Salmonella Mbandaka and Salmonella Havana with 11 circumstances every.

In entire, the 22 sufferers are spread across 10 varied regions with the first reported in Would possibly 2019 and the most contemporary in June 2021. The gender distribution is even and the age range is 0 to 77 years extinct, but 12 circumstances are formative years under the age of 5.

Investigating skill hyperlinks


Sharing of sequence recordsdata from Salmonella isolates on an EU contrivance for public well being consultants discover a connection to old outbreaks with a link to sesame primarily primarily based merchandise.

Rikard Dryselius, a microbiologist at Folkhälsomyndigheten (the Public Health Company of Sweden), said: “Sampling and diagnosis conducted by Livsmedelsverket (the Swedish Meals Company) has ended in findings of Salmonella in different merchandise of tahini and halva. The isolates of Salmonella are presently being sequenced to illustrate the serotypes and if there’s a connection to human circumstances. There are presumably additionally varied serotypes than Salmonella Havana and Salmonella Mbandaka gripping.”

Denmark has two circumstances of Salmonella Mbandaka that are connected to the outbreak. They’re from February 2021 and consist of one child and one grownup.

The Netherlands has identified one matching Salmonella Mbandaka case primarily primarily based on entire genome sequencing. The affected person is a 1.5 one year extinct child with the sample being taken on March 21 this one year.
