TO WHOM IT MAY CONCERN: Several decades ago the Agudath Harabonim issued an Issur (prohibition) on the so-called kosher departments of the treife factories. According to the Issur, if a factory of treife products has also a kosher department -even in separate quarters- at the factory or in proximity thereof, the products of the kosher department are also forbidden. In such a case supervision does not help.
 
We hereby inform the Jewish public that the said Issur is in in full force, and we urge our people to heed this prohibition in order to save themselves from the serious sin of treife. May all those who heed our warning be blessed.
