This is why it is vital that there is at least full-disclosure labelling, without which it will never be possible even to trace the source of a problem. However, it is clear that with the risks involved, even full-disclosure labelling does not go far enough. The long-term effects on health and the environment are currently almost completely ignored by government regulations. Under current regulations, most genetically modified foods will not be labelled. In particular, this includes processed foods.
Medicines often have to be withdrawn because the side-effects turn out to be too poisonous.
In each case, it takes time for the effects to come to light and be evaluated before action can be taken. Genetic engineering poses the greatest danger of any technology yet introduced. Safety testing will never be adequate, because organisms once introduced can never be recalled from the environment and their effects will spread without limit. If action is not taken now, virtually everyone in the world will soon be eating genetically engineered foods and will be at risk. Genetically engineered foods are being introduced without due regard for health, yet any damaging effects will be irreversible.
