With eight current cases and as many deaths from bird flu in Vietnam observers might be forgiven for thinking poultry was definitely off the menu here.

But in a country where the authorities are ineffectual at best, eating chicken, duck and the custom of drinking raw poultry blood persist  particularly in the country side.

Laws continue to be flouted where the government has called for a cull of fowl livestock, while the disease is now being carried by wild birds and the WHO fears catastrophic human-to-human transmission is only a matter of time. Markets still sell live poultry and almost every family in Vietnam keeps two or three chickens despite warnings.
