The rate of total microbial death on four bronzes varied from within 50–270 minutes at 20 °C, and from 180 to 270 minutes at 4 °C. The kill rate of E. coli O157 on copper-nickel alloys increased with increasing copper content. Zero bacterial counts at room temperature were achieved after 105–360 minutes for five of the six alloys.
2005 South Wales E. coli O157 outbreak: E. coli O157: meat: local butcher: 157 [30] 1 [30] Largest E. coli outbreak in Wales. [30] Second largest E. coli outbreak in UK. [30] 2017: 2017 Valley Oak Nacho Cheese botulism outbreak: botulinum toxin: nacho cheese: gas station: 10: 1: A poorly maintained nacho cheese machine lead to the contamination ...
E. coli O157:H7 was believed to have contaminated Nestlé Toll House refrigerated cookie dough. Nestlé recalled its products after the FDA reported there was a possibility that the E. coli O157:H7 outbreak, which sickened at least 66 people in 28 states, might be a result of raw cookie dough consumption.

A deadly E. Coli outbreak linked to McDonald’s has spread to 10 states. See the full list of affected locations and what you need to know.
From 2002 to 2010, a team at the Hungarian Academy of Science created a strain of Escherichia coli called MDS42, which is now sold by Scarab Genomics of Madison, WI under the name of "Clean Genome E. coli", [123] where 15% of the genome of the parental strain (E. coli K-12 MG1655) were removed to aid in molecular biology efficiency, removing IS ...
Since 1993, some strains of E. coli have become resistant to multiple types of fluoroquinolone antibiotics. [citation needed] E. coli was identified as one of the six leading pathogens for deaths associated with resistance in 2019 and that year there were 829,000 deaths globally of people with drug-resistant infection from the pathogen.

Some E. coli strains contain a polyketide synthase genomic island (pks), which encodes a multi-enzymatic machinery that produces colibactin, a substance that damages DNA. About 20% of humans are colonized with E. coli that harbor the pks island. [42] Colibactin can cause cellular senescence [43] or cancer by damaging DNA. [44]
