I have been interested in this issue. I am very much against microchipping of livestock, and certainly wouldn't comply willingly with it for myself.
Most of the sites pull things out of the bill that might suggest a voluntary microchipping of some people with certain complex and high risk conditions. They also pull out parts that are talking about a federal registry of medical devices that indicate pacemakers, prosthetic joints, certain pumps. Those devices are already tracked by the manufacturers and I don't know about a government agency.
Anyway, I'm having trouble sorting through the information since most of the sites that are presenting have their own agendas and bias.
I am curious as to why you are against micro-chipping livestock? As I raise livestock, just putting a tag in their ear don't work! It' has greatly improved our ability to separate herds that tend to run together. Every year I have cattle that walk right thru a barbed wire fence in order to play with his/her partners next door.
I've had some try and tell me the smaller of two calves "must" belong to me! Sorry that turd don't fly! A micro in the ear identifies my investment.
When we had the Mad Cow scare, it sure made it a helluva lot easier to track cattle with a chip!!!!!!
So why the objection?
People is a whole nuther matter! Big Brother knows too much about me already!
ETA:
Most livestock intended for the dining room table don't live long enough to develop much in the way of cancer. Our Bulls have been genetically bred to all but eliminate it in our stock anyway. We don't grow that grass fed crap you buy outa Wally World or Safeway!
Oh yeah, as far as the cattle are concerned the chip is way more non-invasive than the tag the
punch thru their ear! It's more like giving them a shot, and believe me, they get plenty of those!
