Canada Confirms Second Mad Cow Case

WINNIPEG, Manitoba (Reuters) - A final laboratory test has confirmed an Alberta dairy cow had mad cow disease, the second case Canada has found in its herd, an industry source briefed by veterinary officials said on Sunday.

"It is positive," the industry source told Reuters after a briefing from the agency.

The animal did not enter the human food or animal feed supply and there was no risk to the public.

Canada's first home-grown case of mad cow disease was found in May 2003 and cost export-dependent farmers an estimated C$5 billion ($4.2 billion) as trade partners closed their borders to Canadian beef and cattle.

The first U.S. case, found in Washington state in December 2003, also affected a cow that had been born in Canada.

The most recent afflicted animal was born in October 1996, the industry source said.

"You've now got a grouping of three animals born very close together in time," the source said, adding the agency was investigating whether the animals shared a common contaminated feed source.

I'm not convinced the U.S. is going to keep the borders shut this time. As you may know, USDA last week announced they were going to reopen the borders.

Here's the message I received in my overnight emails regarding this issue. It came from an industry source:

BSE CONFIRMED IN SUSPECT ANIMAL, INVESTIGATIONS UNDERWAY
OTTAWA, January 2, 2005 - The Canadian Food Inspection Agency (CFIA) today confirmed that an older dairy cow from Alberta has tested positive for bovine spongiform encephalopathy (BSE). The infected animal was born in 1996, prior to the introduction of the 1997 feed ban. It is suspected that the animal became infected by contaminated feed before the feed ban.

No part of the animal entered the human food or animal feed systems. This finding does not indicate an increased risk to food safety.Canada's public health safeguards have been developed on the assumption that a low, declining level of BSE remains in North America. Canada requires the removal of specified risk material (SRM) from all animals entering the human food supply. SRM are tissues that, in infected cattle, contain the BSE agent. This measure is internationally recognized as the most effective means to protect public health from BSE.

Confirming BSE in this animal is not unexpected. Canada has in place a suite of risk mitigation measures to protect public and animal health, including the removal of SRM from the human food chain, the ruminant to ruminant feed ban, the national surveillance program and import restrictions. As a result, the United States continues to consider Canada as a minimal risk region. As stated in the United States Department of Agriculture press release of December 30th, 2004, the United States would not alter the implementation of its rule to resume trade with Canada.

The infected animal was detected through the recently enhanced national surveillance program. Additional cases may be found as testing of high-risk cattle continues. In 2004, the Government of Canada tested over 22,000 animals.

The CFIA is continuing its investigation and has determined the infected animal's farm of origin. Efforts are now underway to identify any other animals of similar risk. Specifically, the Agency is focusing on two categories of animals: recently born offspring of the infected animal and cattle born on the same farm within a year of the infected animal. This work is proceeding as quickly as possible.

The Agency has also launched a feed investigation to examine what the infected animal was fed early in its life, when infection was most likely to have occurred prior to the 1997 feed ban. Given the age of the animal, it may not be possible to definitively identify a particular feed source as the origin of infection. However, information gathered through investigations and analyses continues to suggest that the feed ban has limited the spread of BSE since its implementation.

In 1989, Canada banned further importation of cattle from the United Kingdom and traced all imported cattle to their Canadian farms of origin, where they were monitored and eventually destroyed. Before this time, when BSE had not emerged as a significant animal health threat, it is likely that some imported animals entered the North American feed system.

The CFIA will hold a technical briefing on January 3, 2005 at 11:00 EST. A media advisory will be issued with additional information.

The bad news is that there is that the cattle could have BSE, just not show any symptoms.

Only if the cattle grower was so unwise as to go against the feed ban restrictions. That's why this isn't terribly worrisome in such an old animal. A younger animal would be a different story and would point to violations of the feed ban.

The best thing on the N. American continent is that we have the land mass available to grow vegetable-based protein to add to animal feed such as soybeans. That wasn't the case in Europe and contributed to the widespread outbreaks of BSE there (again pre-ban of animal byproducts being added to feed). But here, we can grow enough alternative.
