Abstract :
The presence of Escherichia coli (E.coli) indicates a sign of poor
sanitation practices because Escherichia coli can be transferred from hand to
mouth or by passive transfer through food, water, milk, and other products. E.coli
bacteria found in food and beverages that enter the human body can cause
symptoms such as cholera, dysentery, gastroenteritis, diarrhea and various
digestive tract diseases. On the other hand, rujak is a food that has the potential
and high risk of microbial contamination because it is served in a non-hot and
watery state and in blending it is handled directly without using tongs or plastic
gloves. This study aims to determine the presence or absence of E.coli bacteria on
the palms of rujak traders.
The type of research used in this scientific paper is descriptive research.
This research was conducted at the Bacteriology Laboratory of the National
Health Sciences College and the time of the research was on 29 March - 6 April
2021. The sample of this study was the palm swab of a salad trader in Taman Jaya
Wijaya Mojosongo. The sampling technique is quota sampling.
From the examination at the National STIKES Bacteriology Laboratory,
of the 5 samples examined, no pathogenic bacteria (Proteus mirabilis and
Klebsiella pneumoniae) and non-pathogenic bacteria (Serratia marcescens) were
found.
Based on the research that I have done, by identifying the E.coli bacteria
using the Biochemical Test. It was concluded that no Escherichia coli bacteria
were found.
