Nanotechnology in food

Following on from genetic engineering, nanotechnology represents the latest high technology attempt to infiltrate our food supply. Senior scientists have warned that nanotechnology, the manipulation of matter at the scale of atoms and molecules, introduces serious new risks to human and environmental health. Yet in the absence of public debate, or oversight from regulators, unlabelled foods manufactured using nanotechnology have begun to appear on our supermarket shelves
Nanotechnology is a powerful new technology for taking apart and reconstructing nature at the atomic and molecular level. Nanotechnology embodies the dream that scientists can remake the world from the atom up, using atomic level manipulation to transform and construct a wide range of new materials, devices, living organisms and technological systems.

Nanotechnology will take the genetic engineering of agriculture to the next level down – atomic engineering. Atomic engineering could enable the DNA of seeds to be rearranged in order to obtain different plant properties including colour, growth season, yield etc. Highly potent atomically engineered fertilisers and pesticides will be used to maintain plant growth. Nano-sensors will enable plant growth, pH levels, the presence of nutrients, moisture, pests or disease to be monitored from far away, significantly reducing the need for on-farm labour inputs. The concerned organisation, The Action Group on Erosion, Technology and Concentration (ETC) warns in its seminal report “Down on the Farm” in a nanotechnology shaped future, “the farm will be a wide area biofactory that can be monitored and managed from a laptop and food will be crafted from designer substances delivering nutrients efficiently to the body”.

When it comes to matter, size matters. The properties of materials that we notice - color, hardness, conductivity, and so on -- all depend on the nature and structure of the constituent atoms and molecules. With increasing ability to design and build on an atomic and molecular scale -- a reasonable definition of "nanotechnology" -- we are becoming better and better at developing materials with entirely new properties. Those materials, in turn, become the building blocks for more complex systems and entirely new products.

Nanotechnology -- the new threat to food

Following on from genetic engineering, nanotechnology represents the latest high technology attempt to infiltrate our food supply. Senior scientists have warned that nanotechnology, the manipulation of matter at the scale of atoms and molecules, introduces serious new risks to human and environmental health. Yet in the absence of public debate, or oversight from regulators, unlabelled foods manufactured using nanotechnology have begun to appear on our supermarket shelves.

Now, nanotechnology introduces a new wave of assaults on our foods. Nanotechnology is the high technology, atomically processed antithesis to organic agriculture, which values the natural health-giving properties of fresh, unprocessed wholefoods. It further transforms the farm into an automated extension of the high technology factory production line, using patented products that will inevitably concentrate corporate control. It also introduces serious new risks for human health and the environment.

The food and agriculture industries have been investing billions of dollars into nanotechnology research, with an unknown number of unlabeled nano food products already on the market. In the absence of mandatory product labelling anywhere in the world, it is impossible to tell how many commercial food products now contain nano ingredients. The Helmut Kaiser Consultancy Group, a pro-nanotechnology analyst, suggests that there are now over 300 nano food products available on the market worldwide. It estimates that the global nano food market was worth US$5.3 billion in 2005 and will rise to US$20.4 billion by 2010. It predicts that nanotechnology will be used in 40% of the food industries by 2015.
