Food safety will be a major problem in Japan. Supermarket chains usually do not want to release any information about the origin of the food they sell. Addresses provided on the wrapping may indicate just an intermadiary company, e.g. a distributor, a subsidiary, or the packaging company.

Sooner or later consumer confidence will be destroyed because of radiation risks. It will be difficult for the food consumers to develop any trust in the food they can buy and eat. Chances are high that any domestic product will contain some ingredient that is contaminated. I expect gradual, hidden poisoning of the Japanese people even in uncontaminated areas.

Do you really consider it a fair competition: your brain against a device that has a sales price of $150?
