Q:

What is the OU’s position regarding genetic engineering?

A:

There are two dimensions to this issue. First, there is the health concern. Is it safe to consume genetically altered foods? This question is presently a matter of great public debate. Where does the OU stand on this question?

In Jewish Kosher law, a person is not permitted to eat food that is detrimental to one’s health. Nonetheless, the OU views the determination of whether or not a particular substance poses a health danger to be outside of the realm of its expertise. This issue is not in the purview of a Kosher organization, and should be decided by responsible government agencies and health professionals. In practice, the OU would generally agree to certify a product that the USDA considers to be safe. The presence of an OU symbol on a product should not be misconstrued as an endorsement of the safe status of a product, since, as stated, we view this matter to be outside our domain.

The second issue is as follows. If non-Kosher genetic material is introduced into a Kosher product, does that render the genetically altered material as non-Kosher? For example, if a new strain of tomatoes is developed by introducing genetic material from a pig cell, is the tomato a Kosher entity?

In our opinion, the genetic engineering does not affect the Kosher status. This is the case for two reasons: Firstly, the genetic material is generally microscopic and is not significant enough to change the Kosher status. Secondly, the generic material is only introduced in the initial stage. Subsequently, the genetically altered item produces new offspring, which has not been the recipient of non-Kosher genetic material. The presence of a non-Kosher gene in a tomato does not render as non-Kosher all subsequent tomatoes that are “descendents” of the genetically altered tomato.
