A city social worker sold the personal information of her poor and homeless clients to an accomplice who used it to empty their food-stamp accounts, prosecutors say.

Human Resources Administration caseworker Tara Tisdale, 41, sold the names and phone numbers of the very people she was supposed to be helping for about $25 a pop, court papers state.

Tisdale admitted to detectives that she even copied the victims’ information from paperwork left on her co-workers’ desks, the papers state.

The destitute victims were called by someone posing as an HRA worker and tricked into revealing their food-stamp account numbers and the personal information necessary to change the PIN numbers on their accounts, court papers state.

Shameka Davis, 35, a scammer working with Tisdale, then used the information to steal the victims’ benefits right off their cards, blowing the dough mostly at BJ’s Wholesale Club stores on food and a television, according to court papers and prosecutors.

“Davis was the mastermind of this scheme to target people on food stamps, the poorest people in our society,” prosecutor Ron Carny said at the suspects’ arraignment Thursday.

“People lost their food budget for the entire month. These were people living in shelters with small children. They literally stole food off their table,” said Carny, who spent more than a year investigating the alleged scheme.

Tisdale was charged with misconduct and released on her own recognizance.

Davis, who also illegally collected welfare benefits although her husband is a Department of Sanitation worker raking in $100,000 a year, was held on $100,000 bail on grand-larceny and fraud charges.

Davis’ Facebook page shows her and her husband Kevin cavorting at vineyards on vacation.

The alleged scheme began in February 2012 and netted at least $13,000 from about 25 victims.

“Their calculated scheme cost many people — including some homeless — to go without their benefits for weeks,” Brooklyn District Attorney Ken Thompson told The Post. “These indictments will ensure that this crime against our most vulnerable will never be tolerated.”

Tisdale’s lawyer declined to comment. Davis’ lawyer, Robert DiDio said, “We’re working on a bail package, and we look forward to litigating the case.”
