Investigations into E. coli outbreaks often fail to find the outbreak strain in food or environmental samples, according to a review.

Scientists used Shiga toxin-producing E. coli (STEC) as a model pathogen to investigate the success of outbreak strain isolation from food or environmental samples during investigations.

The main reasons

Scientists have detailed the process of linking a major E. coli outbreak in the United Kingdom to lettuce.

In May 2024, public health agencies and laboratories identified an increase in stool specimens submissions and patients testing positive for Shiga toxin-producing E. coli (STEC). Whole genome sequencing (WGS) identified serotype O145:H28
