The European veterinarian says biological safety includes strong perimeter fences around pig farms, which are rare in Canada
RED DEER – African swine fever is unlikely to hit Canadian pig farms, but if a deadly disease occurs, it could be uncontrolled.
"Canada is no longer at risk than it has ever been," said Dr. John Carr, European Veterinary Specialist.
The greatest threat may be at the limits where security officials should be in charge. People were able to bring potentially infected flesh with them when they travel, he said at a workshop held at the World Technology Fair in Red Cap on October 24th.
Pigs can take a virus by eating contaminated foods, including sprays or saws, as well as direct contact with humans or other diseases-transmitting animals.
While the disease has been detected in wild pigs, the greater risk is the transport of contaminated meat and meat products, which spread the disease at long distances.
"The illness travels about five kilometers a year. Unfortunately, people travel 100 km-h," he said.
The Japanese found a virus that was smuggled from a swine fever from China, where the disease is a homeless farm.
It is suspected that the disease had landed in the Eurasian land of Georgia when a ship from Africa dumped the waste which pork horses finally consumed.
Truck drivers from Eastern Europe deliver goods across the continent and are theorized to carry food for personal use and throw unwanted parts. Wild boars then eat them and get sick.
China was badly hit, reporting on the first cases last August. The Chinese tried to hold an epidemic north of the Yangtze River, but failed to report cases reported in mid-October.
China kills all pigs within three kilometers of the infected farm.
"So if you do not have an infected case and your neighbor has an infected case, you'll lose your farm anyway," Carr said.
There is no vaccine and the disease is very contagious among domestic pigs and wild boar. It is endemic among pigs in sub-Saharan Africa and Sardinia.
The first sign is a high temperature of 40 C or more. Several surviving animals can continue to spill the virus, Kar said. Animals may show signs of painful joints, and patients may fall. There is a lot of bloody diarrhea in the final setting. Pigs break. Damaged pigs die quickly.
In the bar of one client, the Car saw 10 dead on Monday, 36 died on Wednesday, and 76 died on Friday.
Post-mortem results show an enlarged mucous membrane, a bleeding on the kidneys, and sometimes a heart.
There are some illnesses that look similar, such as the classical swine fever that appeared in the United Kingdom and the United States.
Serious biological safety is needed, including strong perimeter fences around the farm. Pigs can bury and jump fences.
"You need a perimeter fence. Nearly nobody in Canada has a perimeter fence," Car said.
"We have zero biological safety in this country against this pathogen."
Rabobank, in its quarterly pork report, said global pork markets are at risk because the disease disrupts traditional trade flows and raises concerns about biosecurity.
African swine fever found in wild boar in Belgium in September led to quarantine in the region, and 16 countries banned trade with it. These situations are forcing companies to review plans.
"With the eyes of great potential losses, both exporters and importers are reassessing the production needs of 2019," Rabobank said.
