Everything is bigger in Texas, even bird flu amongst cattle. But while there are concerns for Australian dairy farmers they say things are in a state of alert rather than alarm.

More than a dozen tigers were incinerated after the animals contracted bird flu at a zoo in southern Vietnam, officials said. State media VNExpress cited a caretaker at Vuon Xoai zoo in Bien Hoa city saying the animals were fed with raw chicken bought from nearby farms.

Two million Australian chickens have already been killed in the nation's bird flu outbreak — and that's before the deadliest strain of the virus hits our shores. A variant of H5N1, named clade 2.3.4.4b, has killed around 2 billion chickens since 2020.

The H5N1 strain first appeared in geese in 1996 and has caused bird outbreaks since then. Since 2020, a new variant of this virus has led to many deaths among wild birds and farm animals in several countries.
