The Chief Rabbinate is warning the public of lulavs that have been treated with acrylic glue to prevent opening. Its inspectors have found that a significant number of lulavs have undergone a process of being soaked in a bath containing "an acrylic adhesive”.

The Chief Rabbinate said that there are different opinions amongst religious authorities regarding whether lulavs that underwent this kind of "treatment" are kosher. Merchants that sell these lulavs are required to make "full disclosure" to the customer regarding the use of the glue.
