Linezolid- and Multidrug-Resistant Enterococci in Raw Commercial Dog Food, Europe, 2019–2020


Ana R. Freitas, Liliana Finisterra, Ana P. Tedim, Bárbara Duarte, Carla Novais, Luísa Peixe, and from the ESCMID Study Group on Food- and Water-borne Infections (EFWISG)


We describe enterococci in raw-frozen dog food commercialized in Europe as a source of genes encoding resistance to the antibiotic drug linezolid and of strains and plasmids enriched in antibiotic-resistance and virulence genes in hospitalized patients. Whole-genome sequencing was fundamental to linking isolates from dog food to human cases across Europe.


This study has also been press-released by escmid and released yesterday in many places such as the guardian.

Congratulations to Andreia Rebelo et al. for their recent publication involving EFWISG members from different countries and showing the accretion of metal and antibiotic resistance in Enterococcusspp. during the last century.







Researchers from EFWISG contributed to the article "Event-based surveillance of food- and waterborne diseases in Europe: urgent inquiries (outbreak alerts) during 2008 to 2013"

Gossner CM, de Jong B, Hoebe CJ, Coulombier D, European Food and Waterborne Diseases Study Group. Euro Surveill. 2015; 20(25):pii=21166

The authors of the paper conclude that the platform to facilitate the timely exchange of information between countries has strengthened the role of the Food- and Waterborne Diseases and Zoonoses (FWD) network. Combined with outbreak data collected by the European Food Safety Authority (EFSA), the urgent inquiries give a good overview of the outbreaks’ characteristics. Their analysis, however, also showed that the coordination between the risk assessors and risk managers at the EU/EEA level has to improve, particularly when events are reported. They propose to develop cross-sectoral guidelines for outbreak reporting.
