Proof Mad Cow Not From Canada?
From Jean

Jeff - A brucellosis vaccination tag was found on the infected animal and suggests American origins because Canada eradicated that disease and stopped vaccinating for it in the mid-1980's.
Dr. Brian Evans is the chief veterinary officer of the Canadian Food Inspection Agency. Evans is the person who said "that the brucellosis vaccination tag that was apparently found on the infected animal suggests the possibility of American origins because Canada eradicated that disease and stopped vaccinating for that disease in the mid 1980s."

Brucellosis, a contagious disease caused by bacteria of the Brucella group, affects cattle, swine, sheep goats and man and some wildlife.
Canada's national cattle herd was declared Brucellosis-free on September 19, 1985, although monitoring continues. Eradication of this disease was acheived after extensive programs that dated back to the 1940's. At that time it was estimated that 11 % of cattle and 18 % of herds were infected with brucellosis. Efforts to control the disease by vaccination of calves with Strain 19 Brucella abortus vaccine reduced the incidence to 5% in 4 years. In 1957 a national test and slaughter program was introduced, resulting in elimination of the disease 28 years later. In cattle, brucellosis affects the reproductive organs and causes abortion in pregnant cows. It can be costly in terms of reduced milk yields and calf crops, reduced values of affected cattle, and the expense of replacing animals. Abortion of the fetus is the most obvious manifestation of the disease. This usually occurs in the firth to eighth month of pregnancy. Most infected cows abort once, but some may abort a second or third time. Some cows become temporarily sterile as a result of inflammation of the uterus caused by the disease. When an infected cow aborts or calves, vast numbers of Brucella organisms are shed with the fetus or placenta, or in vaginal discharges which may continue for several weeks. The infected material may be spread about the pasture, yards or stables, contaminating the feed and water and thereby spreading the disease to other cattle.
Bulls may contract brucellosis. When infection becomes localized in the testicles or adjeacent organs of the genital tract, the affected bull usually remains fertile, although fertility and libido may be reduced. Bulls may shed the bacteria in their semen if their genital organs are affected.
The disease in humans is known as undulant fever and may be contracted if a person drinks raw milk from an infected cow or comes into direct contact with infected material such as an aborted fetus or placenta.
