The Department of Agriculture is coming under fire for its “aggressive” ad campaign, including a 10-part series of Spanish-language “novelas,” to convince people to go on food stamps — at a time when one in seven are already enrolled.

The food stamp rolls have swelled since the recession, growing roughly 40 percent since 2009. As of April, more than 46 million people were in the program, which costs $80 billion a year. Yet the USDA is engaged in an ongoing ad campaign to convince those not on food stamps — but still technically eligible — to let down their pride and sign up.

Part of that campaign is the Spanish-language radio “novelas.” The translated scripts, provided to by the USDA, compose a 10-part miniseries called “Hope Park.” In it, the characters are shown persistently trying to convince “Diana” to go on food stamps — known these days as SNAP, or the Supplemental Nutrition Assistance Program — even though her husband works and she doesn’t think she needs it.
