- I can see where people think that the new Pandemic Swine
Flu might be bioterrorism however, it appears that hogs are being infected
- Jeff, you and I both know how difficult it is to eradicate
viruses once they are established in animal populations. Bird Flu H5N1
is a perfect example.
- Wild birds brought H5N1 to new areas and different continents
via migrations, as well as poultry spreading the virus to other poultry
- I am afraid the Swine Flu, Pandemic Swine Flu, is here
to stay. As to mutation, we hope not, but it is already showing signs
- Date: Tue 28 Jul 2009 Alberta Farmer Express Quebec finds
pandemic (H1N1) in hog herd
- An isolated case of the pandemic strain of (H1N1) influenza
has been confirmed in a Quebec hog herd that has since "completely
- The provincial agriculture, food and fisheries ministry
(MAPAQ) said in a release Tuesday [28 Jul 2009] that the strain had been
identified Friday [24 Jul 2009] at the labs of the National Centre for
Foreign Animal Disease in Winnipeg. MAPAQ emphasized Tuesday that no other
case has been reported on any other hog farm in Quebec and no people have
caught the virus from the herd, saying "there is no human case related
to this situation." A MAPAQ spokesman said Tuesday that it's not known
how the hogs caught the virus.
- MAPAQ pathologist Dr Alain Laperle told the Quebec farmers'
newspaper La Terre de Chez Nous on Tuesday [28 Jul 2009] that no one in
the hog farmer's family, nor any of the hog farm's workers or visitors,
has been sickened by the virus. Laperle told the newspaper that the 1st
clinical signs of the flu were detected in the herd at the end of June
. Neither the newspaper nor the ag [MAPAQ] ministry gave the name
or location of the hog farm in question. La Terre also quoted Laperle as
saying that while the vector by which the disease came to the farm may
never be known, the "most probable hypothesis" is that it came
through a human carrier.
- The ministry in its release Tuesday [28 Jul 2009] also
emphasized that Quebec's pork supply is safe to consume and poses no human
- Tuesday's announcement follows a statement Friday [24
Jul 2009] from the Canadian Food Inspection Agency (CFIA) that it will
not quarantine hog herds found to carry (H1N1). The agency hasn't yet made
any official statement on the Quebec case.
- CFIA said Friday [24 Jul 2009] that affected animals
from now on "will be managed using the same veterinary management
and biosecurity practices employed for other swine influenza viruses."
That means "limiting opportunities for (H1N1) to spread to susceptible
animals," the agency said, noting pork slaughter plants have "multiple
inspection points to ensure that only healthy animals enter the food supply."
All herds in which (H1N1) is detected will be monitored to verify that
infected animals recover. As well, CFIA added, surveillance for the presence
of (H1N1) in swine will continue, so as "to detect any changes in
how the virus affects swine and to identify any changes in the structure
of the virus."
- CFIA's decision follows the quarantine it slapped on
a hog herd near Rocky Mountain House, [Alberta], earlier this spring .
The herd was believed to have caught the virus from a person, although
the visitor previously suspected of bringing the virus to the farm from
Mexico has since been ruled out as the carrier. None of the animals that
came down with (H1N1) died from it, but the federal quarantine dragged
on as positive tests continued to turn up within the herd. Faced with an
indefinite quarantine and overcrowded facilities, the hogs' owner, Arnold
Van Ginkel, eventually culled all of his 2000-plus animals last month [June
2009] for animal welfare reasons.
- The only other known case of the pandemic strain of (H1N1)
crossing over from humans to hogs was reported in Argentina earlier this
month [July 2009].
- Since the arrival of pandemic (H1N1) in Canada, the federal
Public Health Agency has reported 58 people have died from this specific
flu strain, as of Tuesday morning [24 Jul 2009]. In all, as of [18 Jul
2009], Canada has reported 10 449 lab-confirmed cases of pandemic (H1N1)
in people, including 1141 hospitalizations.
- Globally, the World Health Organization reports 816 lab-confirmed
deaths due to pandemic (H1N1), and a total of 134 503 lab-confirmed cases
of the virus in people as of Monday morning [27 Jul 2009]. However, the
WHO said in Monday's report, "given that countries are no longer required
to test and report individual cases, the number of cases reported actually
understates the real number of cases."

- This would confirm that the influenza pandemic (H1N1)
virus is essentially benign for pigs. But even so one can hope that the
CFIA investigators FedExed their diagnostic samples overnight to Winnipeg
and did not hand carry them by air; see ProMED-mail posting 20090723.2603.
