The meat I buy doesn't have it.

butcher your own? Vegetarian? Farmer Market buyer? Special brand name? Organic only? Roadkill?

you can still find LOCAL ranchers/farmers who still offer "local-raised" beef/pork/chickens.

When we lived in Colorado, Kansas & New Mexico, we bought our beef by the hind-quarter. It was cut to our specifications and our ground beef was always 95/5 lean.. The places we chose usually ran "specials" too which (in NM) included several lbs of bacon..some chickens, and the best homemade sausage we ever ate)

It was packaged in perfect sizes for our family, and considering the waste & bones we had to trim away when buying at local grocery stores, was probably not all that much more expensive.

Yhese days we do not eat much meat, and our kids are grown, so it;s probably not in the cards for us, but for people with young families, this is still possible in a lot of places.

a web search for your area using the string "Locally raised meat for xxxx", with xxxx being where you live.

that beef has had a dose of antibiotics somewhere along its life. The question posed is, "How can you be really sure?". I would like to think that there is truth-in-labeling, but I gave up that naivite when I found out Tang wasn't 100% orange juice and the government wasn't spying on the ordinary citizen.
I would love to buy organic and grassfed, but am too cynical about being ripped off on a higher priced food that isn't truly organic and grassfed.

antibody free, steroid free, animal protein feed free meat. You just have to look. Also Costco is stocking more meat from such farmers. You just have to make an effort to look and be willing to pay a little more money.

What the Kos article is saying is that antimicrobials should not be used for production and should instead only be used therapeutically under the direction of a vet, which is absolutely correct.

I'd wager that wherever you are getting your meat from is still using antibiotics therapeutically, and if they aren't you should probably reconsider whether you want to buy from them or not. The use of antimicrobials even in healthy animals increases the yield. Some producers have abstained from using them solely to increase production which is the responsible thing to do. That doesn't mean they aren't using them therapeutically, and they should be.

Just because antimicrobials are given to livestock, doesn't mean any significant amount can be found in the end product. The government tests for antibiotic contamination and the standards are measured in parts per million unlike the dosage rates of prescription antibiotics which are measured in milligrams. The current violation rate of the standards is 0.1%, and again we're talking about parts per million vs the normal human therapeutic dosage rate which is not even in the same ballpark.

Its worth the few extra pennies.
