(STEC), can cause severe foodborne disease.
What is E. Coli?

4. ETYMOLOGY
E.coli bacteria were discovered in the human
colon with Latin genitive of colon "colon or large
intestine", in 1885 by German bacteriologist
Theodor Escherich.
Although E.coli bacteria were initially called
"Bacterium coli", the name was later changed to
"Escherichia coli" to honor its discoverer.

Escherichia coli (E. coli) is a Gram-
negative, rod-shaped, facultative
anaerobic bacterium. As they are
facultative anaerobic gram-negative
bacteria, so they belong to the class
"Gamma Proteobacteria".

6. How Does E. coli Make People Sick?
Some types of E. coli make toxins that lead to
diarrhea, UTIs, respiratory problems, and other
sicknesses.
How Does E. coli Make People Sick?
Consuming contaminated food, drinking

10. 1999- E. Coli in Lake Sebu, South Cotabato
Diarrhea has killed 70 people and left one infant
dead in a remote barangay in Lake Sebu town,
South Cotabato. The contaminated water was
the source of the diarrhea and other digestive
problems. Poor sanitation and insufficient
facilities for water treatment were highlighted
by the event.
OUTBREAK IN THE PHILIPPINES

11. In Pangasinan, 2019—E. coli epidemic. Water sources that
were tainted led to the outbreak of coli in Villasis,
Pangasinan. An increasing number of hospital admissions
resulted from the outbreak, as a large number of
inhabitants contracted gastroenteritis. In an effort to
reduce contamination and enhance sanitation and water
quality, the local administration implemented actions. As
per a report released by the Provincial Health Office
(PHO), two people in Pangasinan province passed away
due to severe gastroenteritis this January.

12. 2023 DUMAGUETE CITY – Over the weekend,
further cases of the E. coli (Escherichia coli)
bacteria that killed five people were recorded,
and at least nine water sources from various
places in Vallehermoso town, Negros Oriental
province, tested positive. Due to severe
dehydration from diarrhea, drinking water
infected with E. coli can be lethal.
