Re: Australia - Swine flu hits piggery
Testing feral pigs for swine flu unnecessary, veterinarian says

Feral pigs are unlikely to contract swine flu, according to a Charles Sturt University professor.
Associate Professor in Veterinary Pathobiology Shane Raidal was speaking after Opposition agriculture spokesperson John Cobb called for surveillance of wild pigs in the aftermath of pigs at a Dunedoo commercial piggery falling sick with the A H1 virus.
There are indications the disease had almost run its course at the piggery, according to Livestock Health and Pest Authorities acting health manager Dan Salmon.
?
The number of new cases is decreasing,? Mr Salmon said yesterday.
Mr Salmon said they hoped the pigs will be ?clinically healthy in the next day or so?.
The quarantined pigs will remain on the property until at least seven days after returning to full health.
But Mr Cobb said that should wild razorbacks contract the A H1 virus, it would be nearly impossible to eradicate, mutate and come back as a meaner, nastier, deadlier virus.
?No-one can predict what a disease can do,? Mr Cobb?s office said yesterday.
?Initially no-one believed it (flu) could jump from people to pigs.?
A NSW primary industries department spokesperson disagreed with Mr Cobb.
?It?s a beat-up, we?re not going to entertain John Cobb,? he said. ?Testing feral pigs is not required.?
Associate Professor Shane Raidal agreed testing was unnecessary.
?It would have to be a deliberate attempt by someone to infect a feral pig,? he said.
?Someone would have to deliberately plant something infected and then the pig would have to eat it.?
?There is such a small window of opportunity.?
Mr Raidal said it would be theoretically possible for feral pigs to catch the flu from sick commercial pigs.
?Feral pigs tend to stay away from commercial piggeries. They are smart animals and know they will be shot if they try to get close.
Mr Raidal said if a feral pig got the flu it would recover quickly, would not
spread throughout the feral population, and that it was rare for a free-living animal to catch the flu. 
?A pig would have to sit next to another pig all the time,? he said. :tiphat:
