More than 1,500 confirmed Shiga toxin-producing E. coli (STEC) infections were reported in England and Wales in 2018 and five people died, according to Public Health England data.
A total of 1,553 confirmed cases included 607 laboratory-confirmed cases of STEC serogroup O157 and 612 infections where a non-O157 serogroup was isolated. In 2017, 948 confirmed cases of STEC were reported.
For 334 cases, samples tested positive by Polymerase Chain Reaction (PCR) for Shiga toxin (stx) genes, but STEC was not cultured with more than 300 of these in England.
Four STEC outbreaks caused by O157 affecting 55 people were investigated in 2018. It was not possible to find the vehicle and/or source of infection for the two largest and national outbreaks were a foodborne source was suspected. In one of these, 26 people were ill with 10 needing hospital treatment. In the other, 17 people were sick and four were hospitalised. The other two smaller outbreaks involved a petting farm and an outdoor event.
