Milking it: critics take aim at new environmental guidelines for dairy industry

The US dairy industry is outlining ways ranchers and producers can reduce their environmental impact. But do the new guidelines go far enough?

Brian Medeiros generally keeps the operation at Medeiros & Son simple and traditional. The Central California farm's 2,500 cows get milked three times a day and the resulting milk is shipped to area processors and turned into cheese and butter.

"We're not the newest, most fandangled-type facility," said Medeiros, a second-generation dairy farmer.
