Some 160 employees are to be laid off at US kosher food manufacturer Manischewitz’s Newark, New Jersey, plant, which is to close.

The closure is scheduled for September. The company is shifting production to other plants in the state. A spokesperson was quoted in local reports as saying the closure is taking place during a “challenging time in the retail and grocery business”. 

Manischewitz describes itself as the largest manufacturer of processed kosher food products. It produces matzos, grape juice, macaroons, chicken broth amongst a wide array of kosher products. 

The Manischewitz factory in Newark opened its doors in 2006 as part of an initiative by then Mayor Cory Booker to bring more businesses into the city. 

The company began in Cincinnati, Ohio in 1888 as a matzoh bakery. Its second plant was opened in Jersey City in 1932.

In 2014, Sankaty Advisors, a private-equity arm of Bain Capital, purchased Manischewitz for an undisclosed amount. The previous owner of Manischewitz was Harbinger,  which lost money on its investment in the company,
