Ear tags and disease

Isn't it amazing that the Holstein Association is in favor of national animal ID?
(Well, no, it isn't all that surprising....They maintain a large and lucrative animal database. They make money by identifying animals. Why wouldn't they support it?) It aggravates me to see them pontificate like this no end though. They prey on the ignorance of the general public to make their point of view seem like the right one. I disagree. Pretty strongly, in fact. England has one of the most restrictive animal ID systems in existence. They still have outbreaks of horrific animal diseases. Ear tags don't stop them.

I defy the proponents of NAIS to explain to me how putting expensive ear tags in cows will stop the spread of foot and mouth disease should it come here to the USA. It blows on the wind, flows with the water, is spread by birds, animals, car tires, and people. You could ear tag every domestic animal in the country and it would still do the same thing. Oh, the government says they could find the animals quicker to "do something about it" (read kill cows...the Brits killed a number of herds that didn't even turn out to have the disease. Tough luck for the cows and farmers). Maybe they could find cows faster. However, ear tagging my cows wouldn't do a darned thing to stop the dozens of deer that ramble all over our farm..and the neighbors' farms...and the Amish farms. It won't stop the wind, or the water, the Thruway or the starlings. It won't stop the disease either.
