I think the Canadian requirement to use RFID tags came about because of the BSE outbreak that basically shut down the Canadian cattle industry for awhile. It makes sense to be able to track where a particular animal came from after an outbreak like that. might keep from having to destroy a large number of other unaffected cattle just because you were not sure where they came from or had been. Canada is also using rfid as a means of rebuilding world confidence in Canadian cattle.

I like RFID because it helps me in my operation. I have a premesis ID and don't mind at all that my cattle can be tracked back to me. There will come a day in the US also where all cattle are identified where they came from. Why worry about it if age/source verification brings a premium price?   Unless someone has something to hide. jmho.
