Tattooed Fruit Is on Way

NYT reported A pear is just a pear, except when it is also a laser-coded information delivery system with advanced security clearance. And that is what pears - not to mention organic apples, waxy cucumbers and delicate peaches - are becoming in some supermarkets around the country. A new technology being used by produce distributors employs lasers to tattoo fruits and vegetables with their names, identifying numbers, countries of origin and other information that helps speed distribution. The marks are burned onto the outer layer of the skin and are visible to discerning consumers and befuddled cashiers alike.

If you burn through the outer layer, would that not expose the fruit inside to bacteria that might infect the fruit, and thus the person that eats it?

The process, government approved and called safe by the industry, may sound sinister. But it was designed with the consumer in mind: laser coding could mean the end of those tiny stubborn stickers that have to be picked, scraped or yanked off produce. Sticker-removal duty took Jean Lemeaux of Clarksville, Tex., half an hour one day last week. "I was picking all the little stickers from the Piggly Wiggly off my plums and my avocado pears and my peaches," said Ms. Lemeaux, 76. "Then I had to make fruit salad out of the ones that got hurt when I took the stickers off, and then I had to wash the glue off the other ones before I put them in the fruit bowl."

It is a good idea to wash the fruit anyway, to remove pesticides they may have been sprayed with.

"One time," she said, "I got up the next morning and looked in the mirror and there were two of them up in my hair." The stickerless technology has a broader purpose, too: it is part of the produce industry's latest effort to identify and track, whether for profit or for security, everything Americans eat. Since 9/11, the industry has been encouraged to develop "track and trace" technology to allow protection of the food supply at various stages of distribution. In addition, next year federal regulations will require all imported produce to be labeled with the country of origin.
