WASHINGTON — Imagine the Department of Education pushing an idea called “Teacherless Tuesday,” or the Department of Homeland Security suggesting “Fenceless Friday.” The Department of Agriculture, promoter of all things edible, had a plan this week in an in-house newsletter to promote “Meatless Mondays” in the vast bureaucracy’s employee cafeterias.

Meatless Monday is a global campaign backed by the Johns Hopkins Bloomberg School of Public Health and others to reduce the possible health risks of eating too much meat. The USDA plan was among efforts to “green” its headquarters by turning the cafeterias into “models for healthy eating” featuring locally grown foods.

“The production of meat, especially beef (and dairy as well) has a large environmental impact,” the newsletter said. Greenhouse gases and climate change are byproducts, it said, as well as wasted energy resources.

By the next day, the meat industry and its allies had herded the idea back into its pen, and before a single legume or piece of tofu could get a spritz of olive oil and a dusting of parsley and be labeled “entree,” the notion was history.

“USDA does not endorse Meatless Monday,” the department said in a statement. The information on its website “was posted without proper clearance and it has been removed.”

But not before the blogosphere and Twitterverse became thick with indignation.

“Heresy!” tweeted Republican Rep. Steve King of Iowa. “I will have the double rib-eye Mondays instead.”

The USDA is tasked with promoting the meat industry, from pigs to poultry and just about everything else edible on four legs or two wings and federally inspected in between. The industry adds nearly $1 trillion to the economy.
