Update of the list of QPS‐recommended biological agents intentionally added to food or feeds as notified to EFSA

EFSA Journal, Volume 24, Issue 1, January 2026.
Abstract The qualified presumption of safety (QPS) process was developed to provide a harmonised safety assessment approach to support EFSA Scientific Panels and Units. The QPS approach assesses the taxonomic identity, body of relevant knowledge and safety concerns of microorganisms intentionally added to the food and feed chain.

Microbiological safety of ungulates meat intended to be frozen and defrosting of frozen ungulates meat

EFSA Journal, Volume 24, Issue 1, January 2026.
Abstract Based on the need for a scientific basis for existing requirements in EU legislation on freezing of meat or for its possible amendment, the opinion compares microbial growth of relevant pathogenic, spoilage and indicator microorganisms within five scenarios of chilling, storage and defrosting of bovine, ovine and porcine meat, using predictive

Replication of plasmids derived from Shiga toxinconverting bacteriophages in starved Escherichia coli [PDF]

, 2011
The pathogenicity of Shiga toxin-producing Escherichia coli (STEC) depends on the expression of stx genes that are located on lambdoid prophages. Effective toxin production occurs only after prophage induction, and one may presume that replication of the

Shiga Toxin–producing Escherichia coli Strains Negative for Locus of Enterocyte Effacement

Emerging Infectious Diseases, 2009
Most Shiga toxin–producing Escherichia coli (STEC) infections that are associated with severe sequelae such as hemolytic uremic syndrome (HUS) are caused by attaching and effacing pathogens that carry the locus of enterocyte effacement (LEE).

Data Warehouse, Bronze, Gold, STEC, Software [PDF]

Proceedings of the 2014 Workshop on the Use of Computational Methods in the Study of Endangered Languages, 2014
We are building an analytical data warehouse for linguistic data – primarily lexicons and phonological data – for languages in the Asia-Pacific region. This paper briefly outlines the project, making the point that the need for improved technology for endangered and low-density language data extends well beyond completion of fieldwork.

Emergence of Escherichia coli encoding Shiga toxin 2f in human Shiga toxin-producing E. coli (STEC) infections in the Netherlands, January 2008 to December 2011.

Euro surveillance : bulletin Europeen sur les maladies transmissibles = European communicable disease bulletin, 2014
The Shiga toxins of Shiga toxin-producing Escherichia coli (STEC) can be divided into Shiga toxin 1 (Stx1) and Shiga toxin 2 (Stx2) with several sub-variants.
