It is one of the most potent antibiotics used by U.S. cattle and dairy farmers, the key component in the top-selling drug line of Zoetis, the world’s largest animal health company and is known as ceftiofu

But the strength of the antibiotic ceftiofur – and the frequency with which it’s being misused on farms across America – has created a threat to human health that may overshadow the drug’s effectiveness, a Reuters examination shows.

The U.S. Food and Drug Administration cautioned in 2012 that ceftiofur could pose a “high public health risk,” in part because the drug belongs to a class of antibiotics considered critically important in human medicine. The warning is the FDA’s strongest kind. The concern is that ceftiofur in animals could spawn antibiotic-resistant bacteria, superbugs that can infect people and defeat conventional medical treatment, even when the drug is used as directed.

I ask is this drug in the Candian Food chain and how are we dealing with is..testing I hope and not just assessing as per usual.
