Article on counterfeiting from latest Economist, for those interested. Mentions a competitor to DDT:

"The most foolproof technique for identifying genuine goods involves incorporating materials with special genetic markers into the packaging or product itself. Firms or officials can then literally check an items DNA to ensure that it is real. This is more expensive than other anti-counterfeiting measures, but companies with very valuable wares, such as the grandest wineries, are splurging on it. James Hayward, the boss of DNA Applied Sciences, which sells such technology, insists that new clients are knocking down our door, in spite of the recession."
