2-minute video about health risks from gene-edited food:

Dr Michael Antoniou, warns that the risks from gene editing of food include the possibility of the presence of new toxins and or allergens.
With Dr Michael Antoniou, London based molecular geneticist
In the medical research community, it is not disputed that gene-editing techniques are genetic modification (GM) procedures that give rise to genetically modified organisms (GMOs). These procedures and their products carry risks that require strict regulation. In other words, contrary to GMO advocates' claims, the risks from gene-edited foods are far greater than from conventional breeding.

Dr Michael Antoniou 
These slides (see pdf) by Dr Michael Antoniou explain that gene editing technology is imprecise and causes widespread damage to the DNA of the organism.
This damage can alter gene function leading to a changed composition of a gene-edited crop plant, including the possibility of production of new toxins and allergens. He explores the flaws in the concept of agricultural genetic engineering.
