When the drug company Merck Animal Health announced plans to suspend sales of its Zilmax feed additive last week, many observers were shocked.
Yet concern about Zilmax and the class of growth-promotion drugs called beta agonists has been building for some time.

It's back-to-school season for college students — and President Obama plans to be right there with them.
The president will spend the next two days on a bus tour of New York and Pennsylvania that includes stops at three colleges and a high school. At each stop, he'll be talking about ways to make college more affordable.
The president's big black bus will make its first stop at the University at Buffalo on Thursday — the same day incoming freshmen will be moving in, hauling suitcases and mini-refrigerators.
The president's education tour is part of a broader campaign aimed at boosting the fortunes of the middle class. A study out today shows just how widespread the nation's economic pain has been. It finds that over the past decade, wages have been flat or even declined for the bottom 70 percent of American workers. NPR's Jennifer Ludden has that story.
