Kosher diners are starting to think about what goes on behind the counters where they eat, according to the Orthodox ethics organization Uri L’Tzedek. Three Bergen County restaurants have thus far signed up for the organization’s year-old ethical kashrut seal and a fourth will be announced later this month.

Rabbi Shmuly Yanklowitz, then a student at Yeshivat Chovevei Torah in Riverdale, N.Y., founded Uri L’Tzedek in 2007. The organization unveiled the Tav HaYosher — the ethical seal — last year to reward businesses that recognize what its Website refers to as “The right to fair pay. The right to fair time. The right to a safe work environment.”

So far, 39 restaurants in New Jersey, New York, Maryland, Pennsylvania, and Illinois have signed up.

“It’s the next wave of 21st-century Jewish activism,” Yanklowitz said. “The simple act of a consumer choosing where to buy a sandwich is a matter of Jewish ethics. The act is so easy and the effect is so meaningful.”

Locally, Teaneck’s Noah’s Ark and Shelly’s Café and the frozen yogurt retailer 16 Handles at the Westfield Garden State Plaza in Paramus have signed up for the certification. A third Teaneck restaurant is expected to be announced next week, Yanklowitz said, adding he could not disclose any further details of its identity.

In addition to the businesses that have received its certification, Yanklowitz said Uri L’Tzedek has received commitments from synagogues, federations, schools, and other organizations and individuals to patronize only restaurants that have the seal. The recognition also sends a message to the non-Jewish community that watched the Agriprocessors scandal unfold in the media, he said.

“Many consumers have become disillusioned by the ethics of the kosher community,” Yanklowitz said. “By upholding the name yashrut, ethics, it expands the kosher clientele.”

When a restaurant signs up, a Tav Yosher compliance officer — one of some 60 volunteers — reviews the business’s payroll and other records and speaks privately with the employees. These inspectors are trained to review business ledgers and fluent in other languages to better communicate with non-English-speaking workers. The inspectors then return every two to three months to check the books and interview employees. The certification is free to businesses.

The Rabbinical Council of Bergen County, which oversees the kosher supervision of most of the area’s kosher restaurants, would allow restaurants to make their own decisions regarding the seal, said its president, Rabbi Larry Rothwachs of Teaneck’s Cong. Beth Aaron. Rothwachs declined further comment until he could learn more about the certification.

Calls to the manager of the 16 Handles Paramus branch, which received the Tav HaYosher last week, were not returned. The 16 Handles in Manhattan also carries the certification.

Noam Sokolow, owner of Noah’s Ark and Shelly’s, told this newspaper that the community was outraged by ethical violations uncovered in recent years and wanted reassurance about local establishments.

“We’ve always felt we want our restaurants to be on a level where everyone feels comfortable,” he said. “It was an opportunity for us to have an additional agency supervising an aspect we feel is important.”

Neither of his Teaneck restaurants nor his Manhattan Noah’s Ark restaurant, which also carries the certification, had to make any changes before Uri L’Tzedek awarded the Tav Yosher, he said. After the certificate appeared in his stores’ windows, however, customers began thanking the management, he added.

“They want to see people here locally are following the rules,” he said.

The Jewish community as a whole reacted very responsibly following the Agri fallout and has overcome the challenges it presented, he said.

“As long as we can move forward and do something constructive with the information that we have, we become better people,” Sokolow said. “It’s an evolution.”
