Abstract

Escherichia coli O157:H7 is a strain of E.coli which has ability to produce toxin known as shiga-liketoxin. Shiga like toxin can cause colitis haemorrhagic and hemolytic uremic syndrome in human.

The type of captive floor, which made from cementwas higher risk than cattle that was raised in captive floor which were made from non cement with oddsratio value 6.22.
