" Suspected poisoning case linked to Chinese medicinal herb
The Centre for Health Protection (CHP) of the Department of Health today (April 20) urged members of the public not to collect or consume any unknown plants from parks or the countryside as they may be poisonous.
The call followed CHP's investigation into a suspected poisoning report involving three members of a family, a 53-year-old father, a 54-year-old mother and their 19-year-old son. They developed dizziness, generalised weakness and heaviness of the eyelids one hour after taking broth containing a herb thought to be a Chinese medicinal herb, Cassytha Filiformis, that they collected while hiking in the neighbourhood of Luk Keng on April 12.
They sought medical treatment at Pamela Youde Nethersole Eastern Hospital the next day and were admitted to the hospital. The three were discharged on April 14 in stable condition.
Suspected poisoning related to consumption of puffer fish
The Centre for Health Protection (CHP) of the Department of Health today (April 20) called on people not to consume puffer fish following a report of suspected poisoning associated with the consumption of such fish.
The affected were a 57-year-old man and a 59-year-old woman, who developed weakness, limb numbness and dizziness about seven hours after consuming a puffer fish they bought from a wet market for dinner yesterday (April 19). They were admitted to Pamela Youde Nethersole Eastern Hospital on the same day and are now in stable condition.
A CHP spokesman said puffer fish contains tetrodotoxin, a heat-stable toxin which does not decompose with boiling or cooking."
