associated with leafy greens has been the source of ongoing enteric illness since late 2016, according to research published in a Centers for Disease Control and Prevention journal.
"We typically think of foodborne illness as either part of an outbreak or not," Chen told The Washington Post."In 2019 we switched to using whole genome sequencing to look at the DNA of a strain and track the bacteria which cause foodborne illness. With this tool we can see if multiple outbreaks are caused by the same strain, and link related illnesses over months and years. We call strains that recur, are emerging or persisting over time REP strains of bacteria.
This transmission electron micrograph from Jan. 1, 1995, revealed some of the ultrastructural morphology of a flagellated Escherichia coli O157:H7 bacterium.environmental sources have also been the source of outbreaks, the authors noted. "More recently, contaminated leafy greens have been recognized as a major source of E. coli O157:H7 illnesses and outbreaks. In foodborne illness attribution estimates for 2020 based on outbreak data, 58.1% of E.
