Vendors of live chickens are not adhering to a set of hygiene rules and guidelines aimed at reducing the risk of bird flu outbreaks, with many slaughtering chickens bare-handed and some keeping poultry in overcrowded cages.
This comes a day after the government said it would shelve a central slaughterhouse plan - once touted as essential to prevent bird flu - saying the risk of outbreaks had dropped.
The vendors are also breaching requirements to keep the organs of slaughtered birds in a refrigerator and to keep the cages at least 30 centimetres above ground.
The requirements - which vendors must observe to keep their licences - were put forward by the Food and Environmental Hygiene Department in 2001. There is also a set of hygiene guidelines vendors are advised to follow.
The department said that since 2001, eight wet market vendors had had their licences revoked for not meeting hygiene requirements.
Five appealed to the Municipal Services Appeals Board, which exercised discretion in three cases, allowing them to resume trading.
