* Verocytotoxin-producing isolates (data from PHE’s VTEC Enhanced Surveillance System).

** Data from PHE’s Second Generation Surveillance System (SGSS). These data include salmonella infections for which no serovar result is available (ie non-serotyped salmonella spp.) and which therefore are not directly comparable to data reported before 2015.
