The recent outbreak of Foot-and-Mouth Disease in Europe has given a

whole new meaning to the term "biosecurity" on the farm.

Foot-and-Mouth Disease (FMD) virus is one of the most contagious

diseases of cloven-hoofed animals such as cattle, sheep, hogs, goats

and deer.

UW-River Falls/Extension veterinarian and animal health specialist

Dr. Larry Baumann said, "Most farmers in Wisconsin have never dealt

with an animal disease of this magnitude and severity, so it is very

important that everyone be extremely vigilant against this animal

disease entering the United States."

If you are planning a trip to Europe, especially to England,

Scotland, Wales, France or Belgium, or if you plan to host visitors

from these countries, precautions must be taken to help prevent the

spread of the disease. Farmers are being advised to close their

farms to visitors who have been in Europe within one week prior to

the farm visit.

Baumann recommends a one-week minimum quarantine period in which

travelers returning from Europe or European visitors arriving in

Wisconsin have absolutely no contact with domestic animals and stay

away from farms and zoos.

The virus can be spread by the wind, people, clothing, or on the

tires of vehicles, surviving for long periods on shoes and clothing.

It can also be spread by contaminated hay, water and manure. The

airborne virus can travel on prevailing winds for up to 40 miles,

making containment very difficult. The disease does not pose a health

threat to humans, although they can spread it on their clothing and

shoes. Disinfection or laundering is necessary to kill the virus.

Dr. Simon Peek, clinician with the UW-Madison School of Veterinary

Medicine said, "The predominant means of spread in any FMD outbreak

will be the movement of infected animals, feed, byproducts and the

vehicles used for their transport to sales, auctions and abattoirs."

"While any animal or animal product can carry the virus, it's easier

to control the movement of animals and animal products than to

control the movement of people," Baumann said. "It is theoretically

possible for a person to be on a farm in Europe one day and walk onto

a farm in Wisconsin the next day."

Efforts to control the spread of FMD include a British ban on moving

livestock. According to Peek, the outbreak has grown from 30 farms to

over 100 in the past week. The United Kingdom has closed public parks

and pathways and canceled horse races and other sporting events to

curb public use of the countryside. The European Union banned the

export of live animals, meat and dairy products.

"These temporary control measures are based on animal health, not

food safety," said Barbara Ingham, UW-Madison/Extension food science

specialist. "Meat, fresh milk and other food products may carry the

virus but are safe for human consumption."

If the FMD virus should spread to the U.S., the disease could spread

rapidly because of routine livestock movements. Its economic impact

would be widespread and the consequences for animal health would be

catastrophic. If the FMD virus occurred on a farm, all animals on the

farm and neighboring farms would be destroyed and burned immediately.

Since the Feb 20 FMD outbreak in Britain, 48,000 cattle have been

slaughtered and 37,000 are scheduled for slaughter with more cases

expected.

The U.S. has been free of Foot-and-Mouth Disease since 1929. The

disease is still found in parts of Africa, South America, Asia and

Europe. To learn more about the disease, visit the USDA Animal and
