Scientific
name:
Puccinia horiana Henn.
Common name:
Chrysanthemum white rust
|
|
|
Native To: Asia
Images: Invasive.org and Google
Impact: Has become established
throughout most of the world. There have been several
outbreaks in the U.S., but the disease has been
eradicated each time. Fungus that infects and kills
chrysanthemum. If established
in the U.S., chrysanthemum white rust could have
significant impact on both greenhouse and outdoor
chrysanthemum plants.

Scientific name:
Family Flaviviridae, genus Pestivirus
Common name:
Classical swine fever, hog cholera
|
|
|
Native To: Origin unknown;
may have come from hogs imported from England or
the European continent.
Images: Google
Impact: Highly
contagious, viral disease of pigs that is usually
fatal. The virus is most often transmitted through
the ingestion of contaminated feed or garbage.
Used to be endemic to the U.S., but hog
cholera was eradicated 1978. The disease is still present
in many countries, so there is a risk that it could
become established in this country once again.
While classical swine fever does not cause foodborne
illness in people, economic losses to pork producers
would be severe if the disease were to become established
again in this country.

Scientific
name: Family Picornaviridae, genus Aphthovirus
Common name:
Foot and mouth disease, hoof-and-mouth disease
|
|
|
Native To: First observed
in 1514 in Italy.
Images: Google
Impact: Contagious
disease of cattle, swine, sheep, goats, deer, and
other cloven-hoofed animals. Nine Outbreaks of foot
and mouth disease occured in the U.S. between 1905
and 1929. It is widespread through
the world, but it was eradicated from the U.S. in
1929. Foot and mouth disease is considered to be
the most economically devastating livestock disease
in the world, and represents a worst-case scenario
for livestock diseases because of the variety of
species involved, rapid spread, and difficulty in
controlling outbreaks. The 2001 FMD outbreak in Great
Britain resulted in the slaughter of more than 6
million animals and an estimated economic loss of
20 billion dollars.
