The Centre for Health Protection (CHP) of the Department of Health today (May 26) reminded people to observe good personal, food and environmental hygiene to prevent intestinal infection caused by E. Coli O157:H7 bacteria.
The appeal came after the confirmation by laboratory test today of a case of E. Coli O157:H7 infection involving an 18-month-old boy living in Kowloon City. This is the first case reported to the CHP this year.
CHP's investigations revealed that the child developed fever and vomiting on May 5. He was admitted to Queen Elizabeth Hospital on May 12 and was discharged on May 14. He had no travel history during the incubation period. All his home contacts were asymptomatic.
An investigation by CHP is in progress.
A CHP spokesman said that in general E. coli O157:H7 could be contracted through consumption of undercooked contaminated food or contaminated water, or transmitted from person to person through the faecal-oral route.
"However, the bacteria can be killed at a cooking temperature of around 75 degrees Celsius for two to three minutes," he added.
"People are advised to cook food thoroughly. The core temperature of food should reach 75 degrees Celsius for two to three minutes.
"People should observe good personal and environmental hygiene to avoid person-to-person transmission of the bacteria through faecal-oral route. They are advised to wash hands thoroughly particularly before handling food; before eating; after visiting toilet and after changing diapers for their babies," the spokesman said.
There was one case in 2006 and 2007 respectively. No cases were recorded in 2004 and 2005.
